The Infineon TLE8082ESXUMA1 is an Engine Management Power Management IC (PMIC) housed in a PG-TSDSO-24 (24-pin TSSOP with exposed pad) package. It integrates a 5 V supply output, four low-side drivers, and an SPI control interface for small-engine and motorcycle ECU applications. According to Infineon's product page, the device accepts a wide 6 V to 40 V input voltage range, making it suitable for 12 V and 24 V automotive battery systems. Engine management PMICs are highly integrated power and driver ICs that combine a microcontroller-compatible supply rail, multiple low-side switches, communication interfaces, and protection features in a single package. They sit at the top of the small-engine ECU power tree, replacing discrete regulators plus discrete MOSFETs and reducing BOM count, PCB area, and quiescent losses. The TLE8082ES family is positioned in Infineon's TLE808x small-engine PMIC lineup. Key features include integrated 5 V linear or switching supply, four low-side driver outputs for injector or relay control, SPI-configurable diagnostics, and built-in protection such as thermal shutdown, overcurrent limiting, and reverse-battery robustness. The PG-TSDSO-24 exposed pad provides a thermal resistance path that supports sustained operation of the integrated drivers at engine ambient temperatures up to the AEC-Q100 automotive qualification envelope. Architecturally, the TLE8082ESXUMA1 combines an internal bandgap reference, a pre-regulator, a 5 V post-regulator, four gate drivers for low-side N-channel MOSFETs, and an SPI slave for microcontroller communication. This integration lets a small 32-bit MCU control fuel injection, ignition, and sensor power without auxiliary driver ICs. Typical applications include small-engine ECUs for motorcycles, scooters, mopeds, marine outboards, generators, and handheld power equipment. The wide VIN range and integrated drivers are tailored to single-cylinder and small-displacement powertrains where PCB area and BOM cost dominate the design. When designing with this part, ensure the exposed pad is soldered to a sufficient copper pour for thermal relief; sustained low-side driver currents can dissipate significant power. Use the SPI watchdog to detect MCU lockup, and follow Infineon's small-engine reference design for injector flyback sizing. This page synthesizes distributor stock, parametric specifications, design considerations, and drop-in alternatives that supplement the manufacturer datasheet.

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.

It belongs to Infineon's automotive-grade OPTIREG power management family and is offered in three variants: fixed 5.0 V (TLE8366EV50), fixed 3.3 V (TLE8366EV33), and adjustable 0.6 V to 16 V output (TLE8366EV, this part). The exposed thermal pad PG-DSO-8 (3.90 mm body width) provides low thermal resistance for sustained 1.8 A operation. A buck converter (also called step-down switching regulator) is a switched-mode power supply topology that uses an inductor, a synchronous or asynchronous switch, and a control loop to convert a higher DC input voltage into a lower, well-regulated DC output voltage with efficiencies typically above 90 %. Within the power management hierarchy, the TLE8366 sits between a high-voltage battery or bus rail and downstream point-of-load regulators, providing an isolated, regulated intermediate rail for analog, microcontroller, or sensor subsystems. Key features of this variant include 4.75 V to 45 V wide input range (suitable for 12 V and 24 V automotive buses with load-dump transients), adjustable output from 0.6 V to 16 V via external resistor divider, integrated 1.8 A power switch, PWM current-mode control, cycle-by-cycle current limiting, over-temperature shutdown, input undervoltage lockout, and an enable pin that drops quiescent current below 2 µA in shutdown. The switching frequency is fixed, allowing predictable EMI filter design. The TLE8366 uses current-mode control with internal slope compensation, providing excellent line and load transient response. The exposed thermal pad allows direct PCB heat-sinking, supporting continuous 1.8 A output across the automotive -40 °C to +150 °C junction temperature range with proper board layout. Typical applications include automotive ECUs, body control modules, instrument clusters, HVAC controllers, sensor power supplies, industrial 24 V bus systems, and any point-of-load regulation downstream of a noisy or wide-ranging input rail. The wide input voltage range also makes it suitable for battery-powered equipment with deeply discharged cells. When designing with this device, choose the inductor, output capacitor, and bootstrap capacitor per the manufacturer datasheet's reference design values. Place the input ceramic capacitor as close as possible to the VIN and PGND pins to minimize switching-node ringing, and use sufficient copper area on the exposed pad for thermal dissipation at maximum load. This page synthesizes Infineon product-page data, distributor pricing, parametric cross-references, and practical design considerations to give engineers a single, citable reference that complements the manufacturer datasheet.

It operates from a 4.75 V to 45 V input range, drives an external N-channel MOSFET in a step-up (boost) topology, and supports an adjustable switching frequency from 100 kHz to 700 kHz that can be synchronized to an external clock source. A boost controller is a DC-DC switching controller that regulates an output voltage higher than the input by cycling an external power inductor through a low-side switch. The TLE83862ELXUMA1 belongs to the Infineon TLE8386 family of automotive-grade boost controllers, positioned within the broader power management IC hierarchy as a switching controller -> DC-DC controller -> voltage regulator -> power management IC -> semiconductor. Key features include 700 kHz adjustable switching frequency, 4.75 V to 45 V wide input range, low-side current sensing for simplified ground-referenced feedback, external synchronization capability, integrated protection such as overcurrent, overvoltage, and thermal shutdown, and AEC-Q100 automotive qualification. The exposed thermal pad on the PG-SSOP-14-EP package supports efficient heat removal from the controller IC, which is critical when operating at the upper end of the input range. The TLE83862ELXUMA1 uses a peak-current-mode control architecture with a low-side shunt resistor for current sensing, enabling cycle-by-cycle overcurrent protection and good transient response. The switching frequency is set by a single resistor at the RT pin, providing flexibility to optimize efficiency versus component size. The device integrates a high-side gate driver capable of driving logic-level N-channel MOSFETs in boost configurations for input voltages up to 45 V. Typical applications include automotive LED headlight boost converters, pre-boost supplies for downstream buck regulators in 12 V / 24 V automotive systems, USB-PD / Type-C adapter power stages, industrial 24 V to higher voltage rails, and battery-backed boost converters. The AEC-Q100 qualification makes it especially suited for harsh automotive environments subject to load-dump and cold-crank transients. When designing with this part, ensure the input capacitor is sized to handle the pulsating current of the boost topology, and route the low-side current-sense traces as a Kelvin connection to the shunt resistor to preserve current-mode control accuracy. The exposed pad must be soldered to a sufficiently large copper pour to keep junction temperature within the -40 C to +125 C operating range during load-dump events.

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.
TLE8458GXUMA2 - 5V LIN Transceiver with Vreg | Infineon
The Infineon TLE8458GXUMA2 is an automotive LIN bus transceiver with an integrated 5 V voltage regulator, a 10.4 kBd nominal LIN data rate, and an 8-pin PG-DSO-8-16 package. It combines a LIN physical-layer transceiver with a low-dropout regulator intended to power a local microcontroller while the same device communicates over a LIN subnet. The part is offered as a 1/1 transceiver in a tape-and-reel automotive ordering configuration. A LIN transceiver is a physical-layer interface within the broader automotive networking hierarchy. LIN, meaning Local Interconnect Network, is a low-cost serial bus used for distributed vehicle functions such as body electronics, climate-control modules, door controls, lighting, seat controls, and sensor interfaces. A LIN physical-layer transceiver converts logic-level serial data into a bus signal, provides receiver discrimination and fault-tolerant bus behavior, and works with the vehicle's 12 V electrical environment. The TLE8458GXUMA2's principal headline specifications are its integrated 5 V regulator, 10.4 kBd LIN communication rate, and 8-pin DSO package. Integrating the regulator and transceiver can reduce the number of discrete power-supply components near a LIN-connected controller. The regulator output is intended to support the local electronic control unit, while the transceiver provides the connection to the LIN bus. Its integrated architecture also helps keep the power and communication interfaces within one compact device. The device belongs to Infineon's TLE8458Gx family, whose described derivatives include TLE8458GV33, TLE8458GU, and TLE8458GUV33. The available TLE8458Gx family information also identifies compatibility with standalone LIN transceiver functions associated with TLE7259-2GE, although exact package-body equivalence and every electrical limit must be checked before treating that relationship as a PCB drop-in replacement. Typical applications include LIN-connected automotive body-control modules, door and window control units, climate-control panels, ambient-light sensors, seat and roof controllers, switch and actuator modules, and other low-bandwidth vehicle subsystems. These applications benefit from the combination of a local 5 V supply and a LIN bus interface when the module contains a microcontroller requiring both regulated power and vehicle-network communication. A key design consideration is that the LIN bus side operates in an automotive environment while the regulator serves sensitive electronics. Designers should follow the manufacturer's recommended input, output, transceiver, decoupling, grounding, and protection requirements from the official datasheet. Because the supplied verified data does not include complete absolute maximum ratings or detailed pin assignments, those values must not be inferred from generic LIN-transceiver families. This page consolidates verified distributor classifications, family derivatives, package information, and application-oriented engineering guidance. It distinguishes confirmed drop-in family variants from unverified cross-brand equivalents and identifies missing electrical, pricing, pinout, and compliance data transparently rather than estimating values that could compromise an automotive design.

A Li-Ion battery monitoring and balancing IC is a category of analog/mixed-signal semiconductor that continuously measures each cell's voltage and temperature inside a stacked battery pack, balances the state-of-charge across cells, and reports diagnostics to the Battery Management System (BMS) master controller. Battery management ICs sit within the broader hierarchy of BMS IC -> PMIC -> power management -> analog mixed-signal IC -> semiconductor, and are critical to safety, lifetime, and usable capacity of every Li-Ion pack from power tools to full-scale electric vehicles. Key features of the TLE9012AQUXUMA1 include: integrated 5.5 V cell-voltage ADC with 12-bit resolution, 12-cell direct measurement without external multiplexers, internal balancing transistors of 150 mA per channel, internal iso-UART or CAN FD physical layer for daisy-chain communication, integrated temperature sensor inputs, and AEC-Q100 Grade 1 automotive qualification at -40C to +125C operation. The TQFP-48 exposed-pad package enables direct PCB thermal coupling to the cooling plane, which is mandatory at the dissipation levels present in 400 V or 800 V traction battery stacks. Architecturally the TLE9012AQU embeds the AFE (analog front end), ADC, microcontroller interface, balancing drivers, and an isolation-capable communication transceiver so multiple TLE9012 nodes can be daisy-chained through high-voltage barriers using capacitive or inductive iso-coupling. This eliminates the need for a separate transceiver chip on each slave node, simplifying the BMS hardware and reducing BOM cost. Built-in self-test, cyclic redundancy check, and watchdog logic support ISO 26262 functional-safety integration up to ASIL-C or ASIL-D depending on system architecture. Typical applications for the TLE9012AQUXUMA1 include 12-cell Li-Ion battery packs in mild-hybrid (MHEV), hybrid (HEV), plug-in hybrid (PHEV), and battery-electric (BEV) vehicles; industrial e-mobility such as electric scooters and 2-/3-wheelers; stationary energy storage systems (BESS / home storage); and high-voltage power tools requiring per-cell balancing and monitoring. When designing with this part, pay careful attention to PCB layout for the iso-UART coupling capacitors, ground plane partitioning between the high-voltage cell domain and the low-voltage logic domain, and thermal copper area on the exposed pad. Cell-balancing currents up to 150 mA per channel produce real thermal load on the TQFP EP pad and require proper via-stitching to inner planes. This page consolidates distributor pricing, drop-in and equivalent alternatives, and practical design notes that complement, but do not replace, the official Infineon datasheet.

It features a 16-bit Serial Peripheral Interface (SPI) for control, diagnosis, and configuration, plus comprehensive protection including over-current, over-temperature, over-voltage, and open-load detection. A multi-channel low-side driver IC is an integrated circuit that switches multiple resistive or inductive loads to ground using internal MOSFETs, controlled by a digital logic interface. Low-side drivers sit at the bottom of the load path (load connected to supply, switch to ground) and belong to the broader family of power distribution switches, motor/valve drivers, and powertrain switches used in automotive body and engine ECUs. Key features of the TLE9104SHXUMA1 include a 4.5 V to 28 V supply range, very low R_DS(on) per channel for high-efficiency switching, parallel-channel operation up to ~12 A, SPI-configurable dV/dt slew-rate control, and a 5 V VIO logic reference compatible with 3.3 V microcontrollers. The PG-DSO-20-88 exposed-pad package achieves a junction-to-ambient thermal resistance suitable for continuous 3 A per-channel operation with proper PCB copper area. The device is built on Infineon's SMART7 power technology with embedded protection state machine, providing deterministic fault handling required for ASIL-rated systems.

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.

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.

Housed in a PG-LQFP-64-27 (LQFP-64 with exposed pad) package, the part uses a high-voltage Smart Power technology that lets bridge, motor and supply pins withstand up to 90 V, while motor pins tolerate negative transients typical of inductive switching. The IC integrates three half-bridge drivers plus a charge pump, current-sense amplifier, and SPI diagnostics, making it a near-complete solution for 3-phase BLDC motor control. A gate driver IC (also called a MOSFET driver or predriver) is a power-management building block that translates low-current logic-level control signals from an MCU into the high peak currents required to rapidly charge and discharge a power MOSFET gate. In the system hierarchy, gate drivers sit between the microcontroller and the power stage: MCU -> gate driver -> power MOSFETs -> motor. Compared with discrete bootstrap drivers, an integrated multi-channel gate driver such as the MOTIX TLE9180D-32QK dramatically reduces BOM count, improves timing skew between high-side and low-side channels, and centralizes protection functions. Key features of this part include support for battery voltages from 5.5 V to 72 V, programmable gate drive currents up to 1 A source/sink, integrated current-shunt amplifier with adjustable gain, and ASIL-C functional safety support per ISO 26262.

Typical applications are automotive electric water pumps, oil pumps, e-bike and e-scooter traction drives, 48 V mild-hybrid auxiliary drives, BLDC fans and blowers for HVAC, and small industrial 3-phase pumps. The wide input range allows a single PCB design to support both 12 V passenger-vehicle platforms and 48 V commercial-vehicle or mild-hybrid systems, reducing platform SKU count for tier-1 suppliers.
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.

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. This page synthesizes current distributor stock levels, parametric drop-in alternatives, SPI register guidance, and EMC layout considerations that go beyond the manufacturer datasheet, giving transmission engineers a single point of reference for sourcing and design-in.

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.

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.

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.

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.
TLE94112ESXUMA1 - 12-Fold Half-Bridge DC Motor Driver | Infineon
The Infineon TLE94112ESXUMA1 is a protected twelve-fold half-bridge driver designed for automotive motion-control applications, packaged in a PG-TSDSO-24 (exposed-pad) surface-mount housing.

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 architecture uses a high-side DMOS power switch for the 5 V LDO, a low-quiescent linear regulator for the 3.3 V rail, and a differential CAN transceiver compliant with ISO 11898-2. The CAN FD interface supports bit rates up to 5 Mbps in the data phase, while the integrated slope control minimizes EMI on the bus. Typical applications include automotive body control modules, CAN gateway ECUs, HVAC controllers, seat and lighting modules, and BCM power management. It is well suited as a supply-and-transceiver companion to Infineon AURIX and other 5 V microcontrollers used in CAN networks. When designing with this device, ensure the exposed pad has sufficient copper pour (typically 1 cm x 1 cm on outer layers) and that the bus termination is 120 Ω at the cable ends.

What is a Lite SBC? An SBC (System Basis Chip) is a power-management-plus-communication IC that combines multiple functional blocks (LDOs, DC-DC, transceivers, watchdog, wake logic) into one automotive-qualified device. A 'Lite' SBC strips out the DC-DC and most wake logic to deliver the minimum functions at the lowest cost. The TLE9471-3ES sits in the OPTIREG SYS BASICS hierarchy: SBC -> Lite SBC -> single-LDO SBC -> HS-CAN-FD variant. Key features include the 5 V/200 mA main microcontroller LDO with input voltage up to 28 V (load-dump tolerant), an additional 5 V/100 mA LDO with off-board (sensor short-to-battery/ground) protection for sensor supply, a 5 Mbps CAN-FD transceiver compliant with ISO 11898-1:2015, and a 16-bit SPI for diagnostics and control. The PG-TSDSO-24-1 (TSSOP-24 EP) package provides an exposed pad for thermal dissipation of the internal linear regulators. Typical applications include CAN-FD body-domain ECUs (lighting, door, seat modules), sensor cluster nodes, gateway peripherals, and 12 V automotive subsystems. The dual 5 V LDO architecture removes the need for two external regulators, and the integrated transceiver eliminates a discrete CAN PHY, BOM cost, and PCB area. When designing with this part, ensure the input supply is reverse-battery protected upstream (the device tolerates load dump but not continuous reverse polarity). Provide sufficient copper on the exposed pad to keep the main LDO within its SOA at 200 mA continuous load. Use the SPI to mask unused wake sources and to configure the watchdog window.
