TB67H420FTG - 50V 9A Dual H-Bridge Brushed DC Motor Driver | Toshiba
The Toshiba TB67H420FTG is a brushed DC motor driver IC supporting high-current (9.0 A) and high-voltage (50 V) operation, housed in a 48-pin VQFN (7 mm x 7 mm) package. Built on Toshiba's BiCD process, it integrates dual H-bridges that can be controlled independently for two brushed DC motors or in parallel for a single higher-current stepping/brush load, and uses sense-resistor-less PWM current control for simplified board layout. A brushed DC motor driver is a power-integrated circuit that converts low-current logic-level PWM signals from a microcontroller into high-current drive outputs capable of energizing the motor windings. By eliminating external current-sense resistors, sense-resistor-less architectures reduce BOM cost, shrink PCB area, and simplify wiring in cost-sensitive H-bridge designs. The TB67H420FTG sits in the broader taxonomy: H-bridge driver -> motor driver IC -> power management IC -> semiconductor, making it a foundational block for mechatronic subsystems. Key specifications include an absolute maximum supply voltage of 50 V, a peak output current of 9.0 A (continuous ~4.5 A per the official Toshiba product page), built-in Under-Voltage Lockout (UVLO), Thermal Shutdown (TSD), and Intelligent Shutdown (ISD) protection. The device operates from a single power supply (VM) with logic-level inputs, and supports forward, reverse, brake, and Hi-Z modes through standard IN1/IN2 control logic. Fabricated on BiCD (Bipolar + CMOS + DMOS) process technology, the TB67H420FTG combines low-loss DMOS output stages with CMOS control logic on a single die, enabling high-efficiency switching and small package footprint. The exposed thermal pad on the VQFN-48 package provides a low-thermal-resistance path (theta-JA per datasheet) essential for continuous high-current operation. Typical applications include dual brushed DC motor control in robotics and small CNC machines, single-axis stepper motor driving in 3D printers, automated curtain/blind drives, and battery-powered e-mobility toys where 24-36 V battery packs are common. The dual H-bridge mode is also suitable for bipolar stepper control up to the rated current. The 50 V absolute maximum provides substantial margin above 24 V and 36 V industrial bus rails. When designing with this device, always include adequate bulk decoupling on VM (typically 100 uF electrolytic + 10 uF ceramic) placed adjacent to the IC. The exposed thermal pad MUST be soldered to a sufficiently large copper pour (recommended >= 1 square inch) to achieve the rated continuous current without triggering thermal shutdown. Confirm operating mode (dual brushed vs single stepping) before PCB layout, since pin mapping differs.

TC78H660FNGEL - 18V/2A Dual H-Bridge Motor Driver | Toshiba
The Toshiba TC78H660FNGEL is a dual-channel brushed DC motor driver IC that integrates two DMOS H-bridges in a 16-pin TSSOP package, rated for 2.0 A peak output current per channel and an operating supply range of 2.5 V to 18 V. According to the Toshiba product page, this IC can drive two DC brushed motors independently or one bipolar stepping motor, and includes built-in low-voltage lockout (UVLO), thermal shutdown (TSD), and overcurrent shutdown (ISD) protection. The on-chip DMOS output transistors deliver low on-resistance (typically around 0.5 ohm per HS+LS FET at room temperature) which reduces conduction loss and improves thermal headroom in compact 16-TSSOP layouts. A brushed DC motor driver is a power-management IC that uses full-bridge or half-bridge switching stages to commutate a permanent-magnet DC motor electronically, replacing mechanical brushes with MOSFETs. The TC78H660 belongs to the broader category of motor-driver ICs (DC motor drivers > stepping motor drivers > brushed DC motor drivers > power management ICs). Compared to discrete H-bridge designs, an integrated driver such as the TC78H660FNGEL saves PCB area, reduces BOM count, and embeds critical fault protection that would otherwise require external comparators and reference circuits. Key features include 2.0 A peak / 1.4 A continuous per channel, 2.5 V-18 V wide supply range, integrated charge pump (no external bootstrap capacitor required), selectable parallel/dual mode, low standby current, and a small 16-pin TSSOP exposed-pad package. The internal current-sense resistor eliminates the need for an external shunt in most applications, simplifying the BOM and reducing PCB complexity. Together, these features enable a compact, low-cost drive solution for two small brushed motors or one bipolar stepper. Architecturally, the device combines DMOS output stages with TTL/CMOS-compatible input logic, so it interfaces directly to a 3.3 V MCU without level shifters. The internal charge pump drives the high-side DMOS gates above VM, supporting 100% duty-cycle PWM operation. Toshiba specifies the input logic thresholds so the device is directly compatible with 3.3 V GPIO. Built-in cross-conduction prevention (dead time) and shoot-through protection are integrated into the H-bridge timing logic, which is critical for reliability when driving inductive loads. Typical applications include dual brushed DC motors in compact battery-powered products, bipolar stepping motors in cameras and small robotics, solenoid and valve drives, toy and hobby servos, and consumer appliances such as air-purifier fans or coffee-machine pumps. Because the device runs from a single 2.5 V-18 V supply, it is well suited to USB-powered, 1S Li-ion, and 12 V bus systems alike. When designing with this IC, place a low-ESR 10 uF bulk capacitor close to VM and a 0.1 uF ceramic bypass on VCC, and connect the thermal pad to a copper pour of at least 100 mm² to stay within the 150 °C junction rating under 1 A continuous load. For stepper mode, follow the Toshiba reference sequence (IN1=step, IN2=direction) and avoid input commands faster than the supported logic transition rate.

TC78H660FTG - Dual H-Bridge DMOS Motor Driver, 18V, 2A | Toshiba
The Toshiba TC78H660FTG is a dual-channel brushed DC motor driver IC that integrates two DMOS H-Bridges with low on-resistance output transistors in a 16-pin VQFN (3x3 mm) package. It operates from a 1.8V to 18V supply range and delivers up to 2A peak output current per channel, making it suitable for driving two DC brushed motors or one bipolar stepping motor from a single IC. A brushed DC motor driver is a power-management IC that converts low-power logic-level control signals into the high-current push-pull drive required by a brushed DC motor. Within the broader taxonomy, brushed DC motor drivers sit under motor driver ICs, then power management ICs, then semiconductor devices. The dual H-Bridge topology places four DMOS switches per channel so current can be steered in both directions through the motor winding, enabling forward, reverse, and braking functions from a small surface-mount part. Key features include 0.6 ohm (typical) on-resistance per DMOS output, integrated Undervoltage Lockout (UVLO), Overcurrent Detection (ISD), and Thermal Shutdown (TSD). A combined MODE/ERR pin lets a host MCU set operating mode in normal operation while the same pin asserts a low-level fault flag when TSD or ISD is triggered. Pulse-width modulation up to 200 kHz is supported for speed control, and logic inputs are 1.8V-compatible for direct connection to modern low-voltage MCUs. The TC78H660FTG uses Toshiba's proprietary CD-process DMOS transistors, which combine the low conduction loss of DMOS with logic-level gate drive, eliminating the need for external gate-drive circuitry. The exposed thermal pad on the VQFN-16 package lowers thermal resistance to roughly 35 C/W on a 4-layer 1 oz PCB, allowing 2A continuous operation at modest VIN without an external heatsink. Typical applications include 5V/12V dual brushed DC motors in robotics and small appliances, camera pan/tilt heads, vending-machine actuators, USB-powered fans and pumps, and bipolar stepper motors in compact mechanisms. The 18V absolute maximum supply simplifies 2-cell Li-ion (8.4V) and 12V industrial bus designs. When designing with this part, place input and motor bypass capacitors within 3 mm of their respective pins, and stitch the exposed thermal pad to a copper ground plane to keep junction temperature within safe limits at full 2A load.

The Infineon TLE42062GXUMA2 is a fully integrated bipolar H-bridge DC motor driver delivering up to 1.4 A continuous output current, housed in a 14-pin PG-DSO-14 surface-mount package. Designed for automotive and industrial motion control, it operates from a single 8 V to 18 V supply and integrates the four power DMOS half-bridge transistors, charge pump, control logic, and protection circuitry on a single die. Key features include a parallel (TTL-compatible) logic interface, integrated free-wheeling diodes, PWM capability up to 25 kHz, low quiescent current, and full protection against short-circuit, over-temperature, over-voltage, and under-voltage conditions. The H-bridge topology supports bidirectional drive of a single brushed DC motor or two solenoids with full four-quadrant operation (forward, reverse, brake, high-impedance). Technically, the device uses Infineon's SPT (Smart Power Technology) process to co-integrate vertical power DMOS transistors with bipolar control circuitry, achieving typical R_DS(on) around 700 mOhm at 25 C per leg. The integrated charge pump generates the gate drive for the high-side DMOS, eliminating the need for an external bootstrap capacitor and simplifying PCB layout. Typical applications include automotive throttle and flap actuators, HVAC blower and blend-door motors, headlight beam-leveling drives, body electronics such as mirror adjustment and seat-positioning motors, as well as industrial small DC-motor drives, valve actuators, and robotic actuators operating from a 12 V bus. When designing with the TLE42062GXUMA2, ensure adequate PCB copper pour on the exposed pad for thermal dissipation - at 1.4 A into a low-impedance motor, continuous dissipation can exceed 1 W. Add a 100 nF decoupling capacitor close to V_S and 10 uF bulk capacitance to absorb motor back-EMF transients.

TLE7189F - 3-Phase Bridge Driver IC | Infineon Technologies
The Infineon TLE7189F is a 3-phase motor driver IC that controls 6 to 12 external MOSFETs forming the converter for high-current 3-phase BLDC motor drives in the automotive sector. It supports up to 30 kHz PWM switching frequency, integrates short-circuit detection and diagnostic features, and is AEC-Q100 qualified. The device is housed in a 48-pin PG-VQFN (VQFN-48-4) power package with an exposed thermal pad for superior heat dissipation under high-side/low-side gate-drive switching losses. A 3-phase bridge driver IC belongs to the broader category of gate drivers (also called motor driver pre-drivers or half-bridge drivers) within the semiconductor power management hierarchy: gate driver -> motor driver IC -> power management IC -> semiconductor. It functions as the intelligent control interface between a low-power microcontroller PWM block and a high-current 3-phase MOSFET bridge, handling level shifting, dead-time insertion, charge-pump generation, and protection logic. Without such drivers, microcontrollers cannot directly switch the multi-ampere currents required by automotive 48V or 12V brushless DC motors used in pumps, fans, and eBikes. Key features of the TLE7189F include integrated over-voltage shutdown monitored at Vs and VDH pins, short-circuit protection per phase, programmable dead time to prevent shoot-through, a charge pump for 100% duty-cycle high-side drive, and an SPI/diagnostic interface for fault feedback. The IC accepts low-battery operation down to 6V (cranking survival) and operates across -40C to +150C junction temperature. The 30 kHz PWM capability supports both trapezoidal and field-oriented control (FOC) algorithms. Typical applications span automotive BLDC pumps (water/oil/fuel), electric power steering (EPS), HVAC blowers, eBike traction drives, and 12V/48V mild-hybrid cooling fans. In each scenario the TLE7189F replaces discrete bootstrap-driver designs, reducing BOM count and PCB area by ~40% while providing ASIL-friendly diagnostic outputs. Designers should place the bootstrap capacitors as close as possible to the BSTx pins, use a low-ESR 1uF to 4.7uF ceramic on VCC, and ensure the exposed pad is soldered to a copper area of at least 1 cm^2 to keep junction temperature within AEC-Q100 limits. The datasheet documents a 29-page revision 2.1 from May 2007; refer to the manufacturer datasheet for the full device specification set.

The Infineon TLE82092SAAUMA1 is an SPI-programmable H-bridge DC motor driver housed in a 20-pin PG-DSO-20-65 power package, designed for safety-critical automotive motion control. It integrates two power MOSFET half-bridges delivering up to 5.5 A continuous load current, supports 4 selectable current ranges, and offers 2 configurable slew-rate settings. An SPI interface provides extensive diagnostic readback for fault monitoring in ASIL-rated systems. An H-bridge motor driver is a power IC that uses four switching transistors arranged in an "H" topology to drive a DC motor or solenoid in both forward and reverse directions from a single supply rail. The TLE82092SAAUMA1 belongs to the broader category of motor drivers and motor controllers within the power management IC family, sitting between microcontrollers and the mechanical actuator. By integrating the power stage, current sensing, and a digital SPI control interface, it replaces discrete MOSFET half-bridges plus op-amp sense circuitry, reducing PCB area and improving reliability in safety-critical applications. Key features include a wide operating supply range of 5 V to 28 V (transient tolerant to 40 V), four programmable current-limit thresholds, two programmable slew rates for EMI tuning, and comprehensive SPI diagnostics including open-load, short-to-ground, short-to-battery, and thermal shutdown flags. The PG-DSO-20-65 exposed-pad package achieves a junction-to-ambient thermal resistance of approximately 36 C/W with proper PCB copper area, enabling sustained 5 A operation without external heatsinking. The device is built on Infineon's SMART7 automotive process technology, combining low-Rds(on) N-channel power MOSFETs with on-chip charge pump gate drivers and a precision current-sense amplifier. The SPI interface operates up to 5 MHz and supports daisy-chaining for multi-device ECU architectures. Internal protection blocks include over-temperature warning, over-current shutdown, under-voltage lockout, and cross-current prevention with programmable dead time. Typical applications include throttle body control, exhaust gas recirculation valves, variable-geometry turbocharger actuators, electric park brake systems, transmission shift valves, and HVAC damper controls. The H-bridge topology and integrated diagnostics make the part especially suitable for systems requiring ASIL-B or ASIL-C functional safety compliance per ISO 26262. When designing with this part, observe the SPI programming sequence during initialization - the device must be configured before the output stages are enabled. Place the bootstrap capacitors close to pins 8/14 (high-side drivers) and use at least 100 nF ceramic decoupling on VCC. Refer to the Infineon application note for PCB layout guidance on thermal copper spreading under the exposed pad.

TLE82422LXUMA2 - 8-Ch Low-Side Constant Current Pre-Driver | Infineon
The Infineon TLE82422LXUMA2 (die name TLE8242-2L) is an eight-channel low-side constant-current control pre-driver IC housed in a 64-pin PG-LQFP-64-4 package, designed for solenoid, valve, and LED driver applications in automotive and industrial systems. Each of the eight channels is independently configurable through the SPI interface and can operate in either direct PWM mode or closed-loop constant current mode by setting the appropriate CM bit in SPI message #1. The device operates from a supply range of 5.5 V to 42 V and is rated for junction temperatures from -40 °C to +150 °C, enabling use in harsh automotive underhood environments. What is a low-side constant-current pre-driver? A low-side pre-driver sits between a microcontroller and external low-side N-channel MOSFET switches, controlling the gate of each MOSFET to regulate current through grounded loads such as solenoids, valves, relay coils, or LED strings. By sensing drain current through an external shunt and modulating the external MOSFET gate, the pre-driver achieves tightly regulated load current independent of supply voltage or temperature variations. The "pre-driver" classification means the IC does not contain the power MOSFETs themselves - this architecture lets designers select external MOSFETs sized for the application's load current and thermal budget. Key features of the TLE82422LXUMA2 include eight independently controlled channels, integrated SPI for diagnostics and configuration, fixed-frequency constant-current control, per-channel current setpoints, comprehensive fault diagnostics (open load, short circuit, overtemperature), and a wide 5.5 V to 42 V supply range. The PG-LQFP-64-4 package provides a low-thermal-resistance surface-mount footprint compatible with standard reflow assembly. Each channel supports a configurable PWM frequency and duty cycle, allowing the same IC to drive mixed load types (e.g., proportional valves and on-off solenoids) from a single device. Architecture-wise, the TLE82422-2L integrates a precision current-sense amplifier per channel, an SPI slave controller with global and per-channel status registers, an internal 5 V logic regulator for digital supply, and gate drivers capable of sourcing and sinking the gate charge of standard logic-level N-channel MOSFETs. The constant-current regulation loop operates at a fixed switching frequency to minimize EMI by placing harmonics at predictable frequencies, simplifying input-filter and EMC compliance design. Typical applications include automotive transmission solenoids, electronic throttle and EGR valves, diesel injection valves, LED driver modules, industrial process control valves, and printer/plotter stepper motor drivers. The eight-channel density is particularly suited to mechatronic modules that require multiple coordinated actuators. When designing with this device, follow Infineon's reference layout for the PG-LQFP-64-4 exposed pad: solder the e-pad to a continuous ground copper pour to achieve the rated thermal resistance and to provide the low-impedance return path required for accurate current sensing. Decouple VS and VCC with low-ESR ceramic capacitors placed within 5 mm of the supply pins. This page synthesizes distributor pricing, drop-in alternative analysis, and practical design notes - including a same-family Infineon alternative - that go beyond the manufacturer datasheet's specification tables to help engineers rapidly evaluate the TLE82422LXUMA2 for their multi-channel actuator and constant-current applications.
TLE8444SLXUMA1 - Quad Half-Bridge Motor Driver, 24V, AEC-Q100 | Infineon
The Infineon TLE8444SLXUMA1 is a protected quad half-bridge motor driver in a 24-pin PG-SSOP-24-7 package, designed for automotive and industrial motion-control applications. Built on Infineon's SPT (Smart Power Technology) BiCDMOS process, the device combines bipolar and CMOS control circuitry with DMOS power stages and integrates four independent half-bridge outputs capable of driving DC motors, stepper motors, bipolar and unipolar loads in parallel interface mode. Key headline parameters include a 24 V supply voltage rating, 0.9 A overcurrent shutdown threshold per channel, and 1.3 Ohm typical on-resistance (RDS(on)) per switch. What is a half-bridge motor driver? A half-bridge driver is a power semiconductor topology containing two switches (high-side and low-side) that together drive one terminal of a load. A quad half-bridge IC integrates four such bridges on a single die, enabling flexible load configurations: two DC motors, one stepper motor (as two full H-bridges), four solenoids, four LEDs, or any combination. These ICs belong to the broader motor driver family, which sits under power management ICs in the system hierarchy (motor driver -> power management IC -> semiconductor). The half-bridge topology is the foundational building block of all H-bridge and 3-phase motor drivers. Key differentiating features include an SPI/parallel control interface, integrated freewheeling diodes, overcurrent shutdown with diagnostics, overtemperature protection, undervoltage lockout, and open-load detection. The BiCDMOS architecture allows logic-level inputs (3.3 V/5 V CMOS compatible) to directly drive the high-current DMOS outputs, eliminating external gate drivers and level shifters. Each half-bridge can deliver continuous load current up to its rated RDS(on) limit, and parallel-mode operation enables higher per-channel current. The TLE8444SL is targeted primarily at automotive body electronics and industrial motion control, where it controls small DC motors, stepper motors, relays, and solenoids. Its AEC-Q100 qualification makes it suitable for under-hood and body modules, while the parallel interface simplifies integration with microcontrollers that lack SPI peripherals. The SSOP-24 package with exposed pad provides low thermal resistance for sustained high-current operation. Typical applications include throttle and flap actuators in HVAC systems, headlight beam-leveling motors, DC and stepper motor control in industrial automation, and solenoid/valve drivers. The integrated diagnostics (open load, short to ground/battery, overtemperature) significantly reduce external protection circuitry. When designing with this device, ensure the supply voltage stays within the rated range and place a 100 nF decoupling capacitor close to the VBB pin. The exposed thermal pad must be soldered to a sufficient copper pour to handle the worst-case dissipation across all four channels. This page consolidates distributor pricing, parametric drop-in alternatives, and practical PCB-level design guidance not found in the manufacturer datasheet, making it a complete sourcing and engineering reference for the TLE8444SLXUMA1.
TLE9166EQXUMA1 - 6 Half-Bridge SPI Motor Driver | Infineon
The Infineon TLE9166EQXUMA1 is a multi half-bridge motor driver IC integrating 6 half-bridges with NMOS output stages, a 25 kHz PWM engine, and an SPI configuration interface, housed in a PG-TSDSO-32-1 surface-mount package. It supports PWM-controlled DC motor commutation and is targeted at automotive door lock and other small brushed-motor body electronics applications. A half-bridge motor driver is a type of motor driver IC that uses multiple half-bridge output stages to switch current through motor windings in response to logic-level control signals. In the broader power management hierarchy, half-bridge drivers belong to the motor driver category within power management ICs, sitting alongside gate drivers, H-bridges, and full motor-controller SoCs that integrate FOC algorithms. Key differentiating features include six integrated half-bridges that can be configured as three full H-bridges, an SPI bus for command and diagnostic readback, integrated protection functions such as over-current, over-temperature, and under-voltage lockout, and a charge-pump (CP pin) that supplies the high-side gate drive. The PG-TSDSO-32-1 package exposes VS (battery supply), VDD (logic supply), the CP charge pump input, six half-bridge outputs, and SPI pins on a single IC. The TLE9166EQXUMA1 uses an NMOS half-bridge architecture with charge-pump-generated high-side gate drive, allowing low RDS(on) switching without the cost and footprint of P-channel devices. The integrated 25 kHz PWM engine handles chopping and freewheeling, while the SPI interface enables per-bridge configuration, current-limit setpoints, and fault-flag readback for ECU diagnostics. Typical applications include automotive door-lock actuators, power-window and power-mirror motors, HVAC damper and blower controls, and other body-electronics brushed DC loads. The wide VS range and integrated protections suit it to 12 V automotive electrical environments subject to load-dump and jump-start transients. When designing with this device, ensure VS is decoupled with a low-ESR bulk capacitor placed close to the IC, follow Infineon's PCB layout guidance for the exposed pad, and configure the SPI watchdog to meet your application's fault-recovery timing. This page synthesizes distributor pricing, drop-in alternatives from the same Infineon half-bridge family, and design notes that extend beyond the manufacturer datasheet.
TLE9180D31QKXUMA1 - 6-Ch Half-Bridge Gate Driver | Infineon
The Infineon TLE9180D31QKXUMA1 is an advanced half-bridge gate driver IC engineered to control six external N-channel MOSFETs forming a three-phase inverter for high-current BLDC motor drives in automotive 12V, 24V and 48V systems. Packaged in a PG-LQFP-64-27 (LQFP-64-EP, 10x10 mm) with exposed thermal pad, it provides non-inverting outputs, integrated current-sense amplifier, and ISO 26262 functional-safety support. Source/sink capability is 1 A typical with a 5.5 V to 60 V supply range and up to 90 V transient tolerance on bridge/motor/supply pins, suiting 48 V mild-hybrid architectures. A half-bridge gate driver is a power-management IC that translates low-power PWM logic signals from a microcontroller into high-current gate-drive voltages capable of rapidly switching large power MOSFETs. It sits between the MCU (control domain) and the inverter power stage (power domain), forming one of the cornerstones of every modern motor-drive or DC-DC converter. The TLE9180 family extends this concept with built-in protection, current sensing and ASIL-aware diagnostics, removing many external components. Key features include six half-bridge channels, programmable dead-time control, integrated charge-pump ready for 100% PWM duty, 5.5 V to 60 V supply range, current-sense amplifier for shunt-based phase-current measurement, and a comprehensive protection set: under-voltage, over-voltage, over-temperature, short-circuit, and cross-conduction prevention. SPI interface provides configurable fault and diagnostic readback. The LQFP-64-EP package exposes a thermal pad that drops theta_JA well below a standard LQFP, easing thermal design at 1 A continuous gate current. Typical applications include 12V/24V/48V BLDC and PMSM motor drives for electric water pumps, oil pumps, fans, HVAC blowers, e-bike traction controllers, and mild-hybrid auxiliary drives. Designers also use it for high-current three-phase solenoid drivers and DC-DC converter synchronous-rectifier control. The 90 V transient tolerance provides headroom for load-dump events in 24 V truck systems. When designing with this IC, ensure the bootstrap capacitors are sized for the maximum PWM period to maintain VGS above the MOSFET Miller plateau. The exposed pad must be soldered to a continuous ground copper pour to keep junction temperature within the -40C to +150C automotive Grade-1 range. Use the SPI window for cyclic diagnostics to meet ASIL requirements. This page consolidates real-time distributor pricing, qualified drop-in alternatives within the TLE9180 family and competing gate drivers, and practical design notes that complement the Infineon datasheet for faster automotive motor-drive design.
TLE9201SGAUMA1 - 6A H-Bridge Motor Driver | Infineon | PG-DSO-12-17
The Infineon TLE9201SGAUMA1 is a 6 A H-bridge driver IC designed for the control of DC motors and other inductive loads in automotive applications, housed in a PG-DSO-12-17 (12-pin exposed-pad SOIC) package. It integrates two half-bridge MOSFET outputs with RDS(on) < 100 mOhm per switch, supports an operating voltage range of 5.0 V to 28 V, and offers fully 3.3 V / 5.5 V compatible logic inputs. PWM/DIR control reduces the number of PWM-capable pins needed on the microcontroller side, and outputs can be pulse-width modulated at frequencies up to 20 kHz with a current limitation threshold of 8 A. An H-bridge (full bridge) motor driver is a type of integrated power stage that uses four switching elements arranged in an H topology to drive a bidirectional DC load (such as a brushed DC motor) from a single supply rail. H-bridge drivers belong to the broader category of motor drivers and motion-control ICs, which in turn fall under power management semiconductors used to interface low-power microcontrollers with high-current electromechanical actuators. By integrating the power FETs, gate drivers, and protection logic into a single IC, the TLE9201SGAUMA1 replaces discrete MOSFET bridges and significantly reduces PCB area and design complexity. Key features include short-circuit protection, over-temperature shutdown, low standby current, SPI-configurable diagnostics, and AEC-Q100 qualification for automotive use. The device also supports load currents above the current limitation threshold (8 A) by entering a fold-back / hiccup mode rather than latching off, allowing sustained fault handling in harsh environments. The TLE9201SGAUMA1 uses an N-channel MOSFET output stage with charge-pump gate drive, enabling low RDS(on) and high efficiency at low VIN. SPI diagnostics provide real-time feedback on fault conditions such as open load, short to battery, short to ground, and over-temperature. The integrated dead-time generation prevents cross-conduction of the high-side and low-side FETs during switching transitions, a critical reliability feature for H-bridge designs. Typical applications include throttle body control, HVAC flaps, mirror adjustment, headlight leveling, and small DC pumps in vehicles, as well as industrial valves, power tools, building automation, and small medical pumps. Any 12 V or 24 V brushed DC motor up to 6 A continuous current is a suitable load for this driver. When designing with this device, ensure that the exposed thermal pad (pin 12) is soldered to a sufficient copper area (at least 1 square inch on a 2-layer board) to keep junction temperature within SOA limits. Place the supply bypass capacitors (typically 100 nF ceramic plus 10 uF bulk) as close as possible to the VBB pin to suppress the high di/dt transients typical of PWM motor switching. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, giving engineers a faster path from selection to qualified PCB layout.
TLE9241QUXUMA1 - 7-Channel Solenoid Gate Driver IC | Infineon
The Infineon TLE9241QUXUMA1 is a 7-channel constant-current solenoid gate driver IC designed for automatic transmission control, integrating six low-side and one high-side driver channels with 8 Hall-effect sensor interfaces and an SPI communication port. Housed in a 48-pin PG-TQFP-48-9 package, it operates across a 4.5 V to 5.5 V logic supply range with a separate high-voltage VBAT domain and a peak load current capability of up to 7.5 A per channel, making it purpose-built for hydraulic solenoid valves in modern automatic transmissions. A solenoid driver IC is a specialized mixed-signal semiconductor that translates digital commands from a transmission control unit (TCU) into precisely regulated analog currents flowing through inductive loads such as pressure-control valves, shift valves, and lock-up clutches. As a category, it sits within the broader power-management IC (PMIC) hierarchy: gate driver -> solenoid driver -> motor/actuator driver -> PMIC -> semiconductor. By replacing discrete PWM drive circuitry and analog current-sense op-amps with a single highly integrated IC, the TLE9241 family dramatically reduces PCB area and improves diagnostic coverage in transmission ECUs. Key features of the TLE9241QUXUMA1 include integrated closed-loop current regulation via internal PWM generation, parallel SPI control of multiple devices for multi-valve TCU scaling, comprehensive fault diagnostics (open-load, short-to-ground, short-to-battery, over-temperature), and an operating temperature range of -40 °C to +150 °C suitable for under-hood automotive environments. The 7.5 A peak current capability per channel supports the high forces required by proportional pressure-control valves during gear shifts. Typical end applications are 6-, 7-, 8-, and 9-speed automatic transmissions (DCT, AT, CVT, e-clutch), electro-mechanical power steering (EMPS) actuation where similar proportional solenoid control is used, and dual-clutch module valve bodies. The Infineon TLE9241QU datasheet documents the SPI register map, dither/waveform control, and EMC behavior relevant for these transmission modules. When designing with the TLE9241QUXUMA1, allocate a 100 nF decoupling capacitor directly on each VS pin and a 10 µF bulk reservoir near the package, plus an exposed-pad thermal land for heat spreading during sustained PWM operation. The SPI bus must be pulled up to the logic VIO rail and protected with TVS diodes for harness transients exceeding ISO 7637-2.

The Infineon TLE94003EPXUMA1 is a protected triple half-bridge DMOS driver IC designed for DC motor control, integrating three independent low-side and high-side power MOSFET half-bridges in a single 14-pin PG-TSDSO package with exposed pad. The IC operates from a 5.5V to 20V supply range and is part of Infineon's TLE94xyz DC motor driver family, delivering integrated multi half-bridge functionality with built-in protection features. According to Infineon datasheet materials, each half-bridge uses DMOS output stages capable of driving brushed DC motors, solenoids, relays, and lamp loads in automotive and industrial environments. A DC motor driver (also called a motor driver IC or half-bridge driver) is a power-management semiconductor that sits between a low-power microcontroller and a high-current motor load. Within the power-management IC hierarchy, the TLE94003EPXUMA1 belongs to the broader category of motor drivers > motion controllers > integrated power switches. By integrating three half-bridges, one chip can drive a single three-phase brushless DC (BLDC) motor, three independent brushed DC motors, or be paralleled into full-bridge configurations for higher-current brushed motors. Key features include 5.5V to 20V supply range, integrated charge pump allowing 100% duty-cycle operation, ultra-low quiescent current in standby, built-in over-current, over-temperature, under-voltage, and short-circuit protection, plus a diagnostic feedback pin. The DMOS output stages are optimized for low on-resistance, which directly minimizes conduction losses and improves thermal performance. The PG-TSDSO-14 package with exposed thermal pad enables efficient heat dissipation in space-constrained automotive modules. Typical applications include automotive body electronics (HVAC flaps, mirror adjustment, seat positioning), industrial automation (small brushed and brushless DC motors, valve control), and consumer appliances. The integrated protection set eliminates the need for many external components, simplifying PCB layout and reducing BOM cost. When designing with this part, observe the exposed-pad PCB layout recommendations: solder the thermal pad to a copper pour of at least 1 cm² for proper heat removal. Use decoupling capacitors rated for the full supply transient range, and configure the SPI/EN/diagnostic pins per the datasheet's typical application circuit to ensure correct fault propagation.

TLE94104EP - Quad Half-Bridge Motor Driver, 5.5-20V | Infineon
The Infineon TLE94104EP is a protected quad half-bridge driver with integrated N-channel MOSFET output stages, designed for automotive motion control such as HVAC flap DC motors. It delivers up to 0.9 A continuous per channel (depending on configuration) from a 5.5 V to 20 V supply in a 24-pin SSOPGA package with exposed thermal pad. An automotive-grade half-bridge driver IC is a power-management building block that combines multiple low-side/high-side MOSFET half-bridges with logic-level control, gate drivers, charge pump, and diagnostic feedback. The TLE94104EP belongs to the TLE94xyz family of multi-half-bridge drivers - a category that sits between discrete H-bridge MOSFET designs and fully integrated BLDC FET drivers. It abstracts the low-level power-stage design, giving the MCU a clean digital interface (SPI or direct-input) instead of bootstrap-capacitor and gate-timing concerns. The TLE94104EP combines four half-bridge output stages that can be configured as 1, 2, 3, 4, 5, or 6 independent half-bridges for parallel high-current loads. The device accepts either a 16-bit SPI command set or direct-input logic pins for control and diagnosis, with adjustable open-load thresholds on two outputs. The integrated charge pump and 5.5 V to 20 V supply range cover the full automotive 12 V bus envelope (including load-dump transients handled externally). Typical automotive applications include HVAC flap and blend-door motors, headlight beam leveling, small grille shutters, and other low-power brushed DC loads that previously required a discrete H-bridge plus protection circuitry. Pairing the TLE94104EP with an automotive MCU such as the Infineon TLE9844 or AURIX family lets designers replace 8-12 discrete MOSFETs, gate drivers, and protection parts with one IC, reducing PCB area by typically 60%. A key design consideration is reverse-polarity protection - the TLE94104EP datasheet requires an external reverse-battery FET because the internal free-wheeling diodes will conduct during reverse polarity, causing reverse current from ground. Also ensure the exposed thermal pad receives adequate copper pour to keep junction temperature within limits when driving high-current loads continuously.
TLE94104EPXUMA1 - Quad Half-Bridge DC Motor Driver | Infineon
The Infineon TLE94104EPXUMA1 is a protected quad half-bridge driver IC designed for automotive DC motor control, integrating four half-bridge output stages with on-board power MOSFETs and 16-bit SPI control in a 14-pin PG-TSDSO-EP (exposed-pad) surface-mount package. The device operates from a 3 V to 5.5 V logic supply and 5.5 V to 20 V motor supply, driving up to four external low-side switches or acting as a fully integrated 4-channel half-bridge driver for DC motors, solenoids, and relays. Each output stage is rated for continuous DC motor current with built-in over-temperature, over-current, and short-circuit protection, and the part is qualified to -40 C to +150 C junction temperature per automotive grade-0 requirements. What is a half-bridge motor driver? A half-bridge driver is a power-conversion building block that switches one terminal of a load (typically a DC motor winding) between a high-side supply rail and a low-side ground rail. Four half-bridges can be paralleled or paired into two full H-bridges, giving flexible bidirectional control of up to four DC motors or two stepper-motor windings. The TLE94104EP belongs to Infineon's TLE94xyz integrated multi half-bridge family, which trades the flexibility of discrete MOSFET gate drivers for the simplicity, diagnostic coverage, and PCB-area savings of an integrated solution. Key features include per-channel current limiting, open-load detection in OFF state, configurable slew-rate control, and global charge-pump generated gate drive for the high-side N-channel MOSFETs. The 16-bit SPI interface provides daisy-chain capability for up to 16 devices on a single bus, allowing scalable actuator counts in body-control modules. Internal thermal shutdown with hysteresis protects the IC from junction over-temperature faults and reports status back to the host MCU through the SPI status register. Typical applications include Heating, Ventilation and Air Conditioning (HVAC) flap control, electronic seat adjustment, mirror folding, sunroof drives, and other low-to-medium current brushed DC loads in 12 V automotive body networks. The wide operating-voltage range also supports industrial 24 V systems with adequate derating, and the small PG-TSDSO-14 package with exposed thermal pad enables compact PCB layouts under the dashboard. When designing with the TLE94104EPXUMA1, ensure the exposed pad is soldered to a copper area of at least 1 cm squared to keep the junction within the safe operating area at maximum motor current. Place the logic supply (VCC) decoupling capacitor as close as possible to the IC pins to prevent logic-level noise from corrupting SPI transactions.

It supports a supply voltage range of 5.5V to 20V, integrates ten 1.5A (typical) MOSFET half-bridge outputs, and provides a 16-bit SPI plus direct-input (DI) control interface with comprehensive diagnostic feedback. According to the Infineon product page, the device can be configured as 3, 4, 6, 8, 10, or 12 half-bridges by paralleling outputs, giving PCB designers flexibility when driving mixed loads. A half-bridge (H-bridge) motor driver is a power-converter topology that uses MOSFET half-bridges in push-pull configuration to drive DC loads bidirectionally. The TLE94110ES family sits in the motor-driver hierarchy as follows: motor driver -> half-bridge driver -> power management IC -> semiconductor. Compared with discrete MOSFET half-bridges, integrated multi-half-bridge drivers reduce PCB area, simplify thermal design by spreading dissipation across the exposed pad, and embed critical protection features such as overcurrent, open-load, and overtemperature shutdown. Key features include 1.5A continuous output current per channel (up to 2A peak, depending on configuration), integrated PWM generators with adjustable dead time, open-load detection with programmable threshold on two outputs, and full short-circuit, overtemperature, and undervoltage protection. The 16-bit SPI daisy-chain capability allows multiple TLE94110ES devices to be controlled from a single MCU, supporting up to 12 half-bridges per chip and beyond via cascade. The device is built on Infineon's smart power technology, combining DMOS output stages with CMOS logic on a single die. The exposed thermal pad provides a low thermal-resistance path to the PCB copper, enabling sustained 1.5A operation across all ten outputs simultaneously with proper board design. The wide 5.5V-20V input range covers 12V automotive bus systems including cranking transients when the input is buffered. Typical applications include HVAC flap motors in automotive climate control, small DC and brushless DC (BLDC) motor driver stages, LED lighting modules with per-string current control, and generic multi-channel solenoid/relay drivers. Its 10-channel density makes it especially attractive for zonal body-control modules replacing discrete relay boxes. When designing with this part, observe the exposed-pad PCB layout guidelines: use at least 6 cm² of copper on top and bottom layers with thermal vias to spread heat from all 10 channels. Configure unused outputs as open-drain or tie them to the supply through a pull-up, and always enable the open-load detection on critical safety loads. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, giving engineers a single, citation-ready reference for automotive multi-motor control designs.

Each of the twelve half-bridge outputs can source/sink up to approximately 0.9 A continuous, and the outputs are freely configurable into parallel, half-bridge, or full-bridge topologies, making the part a single-chip solution for multi-motor DC loads. A serial peripheral interface (SPI) provides output control, diagnostics, and daisy-chain capability for up to sixteen devices. What is a multi half-bridge driver? It is a power-management IC that integrates multiple low-side/high-side FET half-bridges into a single package, replacing discrete H-bridge MOSFET assemblies. Within the broader taxonomy, the TLE94112ESXUMA1 sits as: half-bridge driver -> full/half-bridge driver -> motor driver -> power management IC -> semiconductor. Other members of Infineon's TLE94xyz family span 3 to 12 outputs and offer either direct PWM inputs or SPI control. Key features include per-channel current limiting, over-temperature shutdown, open-load detection, and short-circuit protection to ground or supply. The wide supply range supports 5.5 V to 18 V operation (with load-dump tolerance up to 40 V typical for 12 V automotive systems), and the exposed thermal pad of the PG-TSDSO-24 package provides a low-resistance path to PCB copper for heatsinking. SPI daisy-chaining reduces microcontroller GPIO count when controlling multiple drivers in a vehicle. Typical applications span HVAC flap DC motors, seat-adjustment modules, window lift and sunroof drives, mirror adjusters, and other small brushed-DC loads in body-electronics modules. The integrated protection set reduces external component count and improves functional safety metrics when paired with a host MCU. A design consideration is that even though the TLE94112ESXUMA1 is highly integrated, paralleling outputs to achieve higher continuous current still requires careful thermal layout - the PG-TSDSO-24 EP must be soldered to a sufficiently large copper area to keep junction temperature within the -40 C to +150 C operating range. Always close an input bulk capacitor near the VS pin to absorb load-dump transients.

The SPI interface allows the host MCU to configure diagnostics, protection thresholds, and PWM control parameters. Technically, the device targets 28 V automotive board-net systems. Integrated protection and diagnostic functions - including current sensing support and fault reporting via SPI - reduce external component count and support functional-safety-oriented designs. The exposed-pad PG-VQFN-48 power package provides the thermal path needed for sustained motor-drive operation. Typical applications include automotive BLDC pumps (water, fuel, oil), HVAC blowers and fans, window lifters, and other body-domain motor loads requiring CAN/LIN connectivity. The integrated 5 V regulator eliminates a separate LDO for the MCU. Design consideration: provide adequate PCB copper area under the exposed pad to extract heat from the half-bridge power stage, and follow Infineon layout recommendations for the power and ground returns.

A BLDC motor driver is a power-management and gate-driver IC that converts low-power logic commands from an MCU into the high-current phase-drive waveforms (PWM, commutation) required by three-phase brushless DC motors. In the broader taxonomy it sits under motor drivers and motion controllers, itself a sub-category of power management ICs and gate drivers. Highly-integrated multi-half-bridge parts such as the TLE9561 family further combine supply generation (LDO, charge pump) and communication transceivers (CAN, LIN, SPI), allowing one IC to replace several discrete blocks on a compact ECU PCB. Key differentiating features of the TLE95613QXXUMA1 include four half-bridge outputs (extendable to six via external drivers), integrated short-circuit and over-temperature protection, an SPI control port for diagnostics and PWM generation, and an exposed thermal pad for direct PCB heat-sinking. The wide 5.5V to 28V supply range suits both 12V and 24V automotive bus rails, while built-in charge-pump support enables 100% duty-cycle drive of the N-channel MOSFET half-bridges. The architecture uses an NMOS output stage with adaptive dead-time control, an internal charge pump for high-side gate drive, and a 5V LDO plus 3.3V tracker to supply the host MCU. Diagnostic features include open-load detection, short-to-battery and short-to-ground reporting per output, and a thermal warning/shutdown chain that protects both the IC and the motor winding. Typical applications include automotive HVAC blowers, engine cooling fans, electric water pumps, seat ventilation, and other 12V/24V BLDC or DC motor loads. Designers frequently pair the TLE95613 with Infineon Aurix or AURIX TC2xx/TC3xx MCUs and TLE925x CAN transceivers to form a complete motor-control ECU. Design considerations include providing adequate PCB copper area beneath the exposed pad for thermal dissipation, respecting the max supply rating of 28V including load-dump transients, and using the SPI watchdog to bring outputs into a safe state on MCU loss-of-clock. The high-side gate drive relies on the integrated charge pump, so the external reservoir capacitor value must follow the datasheet recommendation.

TMC262-LA - 60V Bipolar Stepper Driver with StallGuard2 | TRINAMIC
The Analog Devices (formerly TRINAMIC) TMC262-LA is a high-current, high-precision microstepping driver IC for bipolar stepper motors, rated for motor currents up to 10 A RMS and supply voltages up to 60 V, housed in a 32-pin QFN (5x5) package. It provides up to 256 microsteps per full step and integrates the patented StallGuard2 sensorless load measurement, coolStep load-adaptive current control, and spreadCycle low-resonance chopper. The device drives four external N- and P-channel dual MOSFETs, allowing designers to scale the power stage to the application's current and voltage requirements rather than relying on a fixed internal H-bridge. A stepper motor driver is an integrated power-management IC that converts step/direction pulses from a motion controller into the precisely timed, current-regulated H-bridge switching required to commutate a two-phase bipolar stepper. Microstepping drivers such as the TMC262 sit in the broader hierarchy of motor-driver ICs -> power management -> signal-chain/power semiconductors. They are typically used in CNC machines, 3D printers, and laboratory automation where smooth, high-resolution motion and stall detection eliminate the cost of external encoders or limit switches. Key features include an SPI configuration interface for setting microstep resolution, current limit, and chopper mode; StallGuard2 for sensorless mechanical-load measurement; coolStep for energy savings of typically 50 percent or more by reducing current under low load; and integrated protection including overtemperature, overcurrent, short-to-ground, and open-load detection. The QFN-32 (5x5 mm) package exposes a thermal pad with a typical junction-to-ambient resistance of approximately 31 C/W, and the device operates across -40 C to +125 C. Architecturally, the TMC262 combines an SPI-configurable control core with mixed-signal chopper hardware and external MOSFET gate drivers. The high-resolution microstep table and the patented spreadCycle chopper produce sinusoidal current waveforms with low audible noise and minimal resonance, while StallGuard2 measures back-EMF timing variations to infer mechanical load without an encoder. coolStep closes the loop by reducing current as load decreases, lowering dissipation and motor heating. Typical applications include 3D printer and CNC tool-head drives, laboratory liquid-handling robots, pick-and-place stages, and textile or sewing machines. The wide 10 V to 60 V supply range and external MOSFET architecture make it well suited to both 12 V/24 V hobby systems and 48 V industrial stepper axes. When designing with the TMC262, observe MOSFET gate-charge limits and ensure that the external MOSFETs are rated for both the supply rail and the desired RMS current. Use a low-ESR bulk capacitor of at least 100 uF on VM, and keep the charge-pump capacitor close to pins CP1/CP2 to preserve gate-drive strength at low supply voltages.

It operates from a 4.8 V to 46 V motor supply (VS) and a 3.3 V to 5 V logic supply (VCC). The IC supports StealthChop2 for silent operation, SpreadCycle for high-dynamic performance, and integrates stallGuard2 and coolStep for sensorless load feedback. Communication is via SPI, with step/direction and RS-232-style UART options available. What is a stepper motor controller/driver? It is an IC that combines motion planning (a ramp generator that converts target velocity and acceleration into step pulses) and the actual coil-driving H-bridge MOSFETs. The TMC5130A-TA belongs to the integrated stepper driver family, sitting hierarchically between discrete MOSFET gate drivers (e.g., the L6470's predecessors) and full external microstepping solutions. Compared with simple step/direction ICs, the TMC5130A offers on-chip trapezoidal/jerk-limited profile generation, eliminating the host MCU's need to time steps in real time. Key features include microstepping up to 1/256 step, integrated current-sense resistors-less sensing, programmable slope control, internal 1.4 A RMS (2 A peak) per phase, and full protection (short-to-GND, short-to-VS, overtemperature). The device supports 5 V tolerant digital inputs and provides incremental encoder interfaces for closed-loop positioning. Technically, the TMC5130A combines a programmable motion controller (six-point ramp) with a dual H-bridge, dual-sense resistor-free current sense path, and adaptive chopper engines. This architecture reaches 256 microsteps per full step without the resonance penalties of traditional fixed-off choppers, and supports automatic motor parameter identification via the analog/digital feedback loop. Typical applications include 3D printers, CNC routers, laboratory automation, surveillance PTZ cameras, textile machines, and battery-powered robotic drives. Its wide 4.8–46 V range covers both 12 V/24 V industrial buses and 36 V power tool packs. Designers should evaluate VS decoupling (10 µF + 100 nF close to pins), thermal copper area on the exposed pad, and the layout of analog GND vs power GND; the EP must be soldered for proper thermal and electrical performance.

TMC6460 - 36V Fully-Integrated Servo Drive FOC Controller | ADI Trinamic
The Analog Devices (formerly Trinamic) TMC6460 is a 36V fully-integrated servo drive IC combining a hardware field-oriented control (FOC) controller, power stage, current sensing, and feedback engine for 3-phase PMSM/BLDC and DC motors in a single 38-pin TQFN (5x7 mm) package. Its headline parameters include a 36V supply rating, integrated gate drivers for the power stage, on-chip current sensing, and support for I2C, SPI, and UART host interfaces. Background: A fully-integrated servo drive IC is a category of motor-control semiconductor that consolidates the FOC algorithm, the power stage, feedback processing, and current measurement into one chip. Within the broader system hierarchy, a servo drive IC sits under motor driver -> motor control -> power management IC -> semiconductor. This integration eliminates external DSP/MCU FOC computation, external gate drivers, and shunt-based current sense amplifiers, dramatically reducing PCB area and firmware complexity for designers building brushless motion systems. Key features include hardware-accelerated sinusoidal commutation for smooth torque, integrated gate drivers capable of driving external N-channel MOSFETs, integrated current sensing without external shunt resistors in many configurations, and encoder/Hall sensor feedback interfaces. The device supports torque, velocity, and position control modes with a single-chip solution that previously required a DSP/MCU plus external driver stage plus analog front-end. The TMC6460 architecture pairs an ARM-class host interface with ADI Trinamic's proprietary hardware FOC block, offloading the computationally intensive Park/Clarke transforms and SVPWM modulation from the application processor. This hardware-FOC approach delivers deterministic loop timing at microsecond scale, which is critical for low-inductance PMSM motors used in robotics and CNC machines where software FOC on a general-purpose MCU often struggles with jitter. Typical use cases are collaborative robot joints, drone gimbal and propulsion BLDC controllers, surgical and diagnostic medical pumps, CCTV/PTZ camera pan-tilt heads, and laboratory automation stepper-replacement BLDC axes. The wide 36V supply range covers 12V/24V industrial bus rails directly without an intermediate DC-DC stage. Design consideration: Sizing the external MOSFETs and the bootstrap capacitors is the primary design trade-off. The integrated gate drivers source/sink peak currents that must be matched to the Qg of the chosen FETs; under-sized FETs improve switching loss, while over-sized FETs may exceed the driver's drive strength and slow switching edges. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the standalone manufacturer datasheet, giving engineers a single reference to plan trade-offs in robotics, medical, and camera motion subsystems.
