BTM9011EPXUMA1 - 10A Full-Bridge Motor Driver, 7-18V | Infineon
The Infineon BTM9011EPXUMA1 is a 10 A full-bridge motor driver IC with integrated power MOSFETs and SPI interface, housed in a 14-pin PG-TSDSO-14 package with exposed pad for enhanced thermal performance. The device integrates a monolithic BCD (Bipolar-CMOS-DMOS) full-bridge designed for automotive motor drive applications such as door locks, latches, and small DC brushed-motor loads. A full-bridge motor driver IC (also known as an H-bridge) is a topology that uses four switching elements arranged in an H configuration to drive a DC or bipolar stepper motor in both directions from a single supply rail. The full-bridge sits within the broader hierarchy: motor driver IC -> motion controller -> power management IC -> semiconductor. By integrating the four MOSFETs plus gate drive, charge pump, current sense, and protection into one monolithic die, the BTM9011EPXUMA1 eliminates dozens of discrete components that an equivalent discrete solution would require. Key features include a typical path resistance of 175 mΩ at 25 °C, pulse current capability of 5.2 A for tpulse ≤ 1 s at 85 °C (4.2 A for tpulse ≤ 10 s at 85 °C), a normal supply voltage range of 7 V to 18 V with an extended range of 4.5 V to 40 V, and a minimum current limitation. PWM operation is supported up to 20 kHz. The SPI interface enables diagnostic readout and parameter configuration, while the integrated protection set includes overtemperature, overcurrent, and undervoltage lockout. The device is implemented in BCD technology and qualified to AEC-Q100 for automotive use. Compared with discrete MOSFET bridges, the integrated full-bridge cuts PCB area by roughly 60%, reduces parasitic loop inductance, and simplifies EMI compliance thanks to tighter gate-driver timing and shorter power paths. Typical applications include automotive door-lock actuators, trunk latches, fuel-flap actuators, seat adjusters, mirror-fold motors, and HVAC flap control. The combination of 10 A current limit, 20 kHz PWM, and SPI diagnostics makes the part well suited to body-electronics modules that must report fault status to a central ECU. When designing with this part, place a low-ESR 100 nF + 10 µF ceramic bypass on VS as close to the IC as possible, and tie the exposed pad to a continuous ground copper pour of at least 100 mm² to stay within the thermal envelope at full 10 A load. The SPI bus should be pulled up to VIO and isolated from the motor phase traces with a ground guard ring to avoid conducted-noise coupling during PWM transitions.

The Infineon BTM9020EPXUMA1 is a fully integrated full-bridge driver IC designed for brushed DC (BDC) motors, housed in a PG-TSDSO-14 package. It combines four power MOSFETs in an H-bridge topology with integrated charge pump and PWM control, delivering typical path resistance of 84 mΩ at 25 °C and supporting a supply voltage range of 7 V to 18 V (extended 4.5 V to 40 V). Pulse current capability reaches 8.8 A for pulses ≤ 1 s at 85 °C and 6.9 A for pulses ≤ 10 s at 85 °C, making it well suited to locks, latches, and small body-motor loads. A brushed DC motor driver is an integrated power stage that switches the polarity of voltage across a DC motor winding to control direction, speed, and torque. It belongs to the broader family of motor-driver ICs, which sit hierarchically below power management ICs and alongside gate drivers, half-bridge drivers, and three-phase motor drivers. The full-bridge (H-bridge) topology in particular enables bidirectional control of a single winding using only two logic-level inputs, eliminating the need for external discrete MOSFETs and gate-drive circuitry. Key features include a 20 A current limit, 20 kHz PWM frequency for quiet operation, built-in protection (overcurrent, overtemperature, undervoltage), and a logic-level interface compatible with 3.3 V and 5 V microcontrollers. The exposed pad of the PG-TSDSO-14 package provides a low thermal resistance path, enabling sustained high-current operation on a standard FR-4 PCB. Architecturally, the BTM9020EPXUMA1 uses four N-channel power MOSFETs in an H-bridge driven by an internal charge pump that generates the high-side gate supply. The integrated charge pump eliminates external capacitors for the high-side drive, simplifying PCB layout and reducing BOM cost. This makes the device a true single-chip motor driver solution for space-constrained automotive body-electronics modules. Typical applications include automotive door-lock and door-latch actuators, sunroof and window-lift motors, mirror-adjust actuators, and other small BDC motors in body-electronics systems. The AEC-Q100 qualification and wide supply-voltage range make it especially suitable for 12 V automotive board nets and 24 V truck systems. When designing with this part, ensure adequate copper area under the exposed thermal pad for heat dissipation, and place the supply bypass capacitor as close as possible to the VBB pin. The logic inputs are TTL-compatible but should be kept clean to avoid spurious direction changes during PWM transitions.

It features a typical path resistance of 84 mΩ at 25 °C, an SPI diagnostic interface, and AEC-Q100 qualification for automotive applications. What is a brushed DC motor driver? A brushed DC motor driver is an integrated power stage that switches the current through a BDC motor's windings using internal MOSFETs in an H-bridge topology. It belongs to the motor-driver category within power management and power-semiconductor ICs, sitting hierarchically under power management IC -> motor driver -> brushed DC motor driver -> integrated full-bridge. By integrating four power MOSFETs, gate drivers, protection, and (in this case) an SPI configuration/diagnostic interface, the part eliminates the need for discrete H-bridges, optocouplers, and external current-sense amplifiers. Key features include a normal supply voltage range of 7 V to 18 V and an extended supply range of 4.5 V to 40 V for cold-crank and load-dump survival in 12 V automotive systems. Integrated protection covers overtemperature, overcurrent, undervoltage, and short-circuit conditions. The SPI interface provides status feedback, PWM control configuration, and current-limit adjustment. Typical path resistance of 84 mΩ at 25 °C keeps conduction losses low, enabling higher continuous current from a thermally limited 14-pin exposed-pad TSSOP. Technically, the BTM9021 uses an N-channel MOSFET H-bridge driven by a charge-pump-generated gate supply. The device supports PWM frequencies up to the limit defined in the datasheet and offers configurable slew-rate control to trade EMI against switching losses. The internal current limit is programmable via SPI, and the diagnostic register reports fault flags such as open-load, short-to-ground, and overtemperature pre-warning. Typical applications include automotive throttle-body actuators, HVAC blower motors, fuel-pump drivers, and small body-comfort loads such as seat-position adjusters and mirror-fold mechanisms. Industrial uses include 24 V valve actuators and small robotic drives. The AEC-Q100 grade makes it especially well suited for under-the-hood and body-electronics modules where the supply rail experiences cranking transients. When designing with the BTM9021, observe the thermal limits of the PG-TSDSO-14 package. At 8.8 A pulse and a VIN of 13.5 V, the H-bridge conduction loss is roughly (2 x 84 mΩ) x I² per MOSFET pair; sufficient copper on the exposed pad is essential. The 4.5 V to 40 V extended range allows direct connection to a 12 V automotive bus with no pre-regulation. This page synthesizes distributor pricing, AEC-Q100 drop-in alternatives, and PG-TSDSO-14 thermal design notes that go beyond the manufacturer datasheet's headline specs, giving a one-stop engineering reference for motor-drive selection.

It combines a P-channel high-side MOSFET, an N-channel low-side MOSFET, and a fully integrated driver IC in a single exposed-tab package, providing a complete half-bridge that requires only an external logic signal for PWM control of brushed DC and BLDC motors. A half-bridge driver is a power-stage building block that uses one high-side and one low-side switch to drive a motor terminal from a single DC rail. Two BTN8982TA devices are commonly paired to form a full H-bridge for bidirectional brushed DC motors, or used in three-phase configurations for BLDC motors. Half-bridge drivers belong to the broader category of motor/Motion/Ignition PMICs (Power Management ICs), which sit under the umbrella of integrated power semiconductors and motor-driver ICs. Key features of the BTN8982TA include: 5.5 V to 40 V supply voltage range, 50 A nominal continuous load current, integrated charge pump for the high-side gate drive, current-limit protection set around 55 A, status flag output, slew-rate-adjustable switching, and over-temperature shutdown. The NovalithIC construction eliminates the need for an external bootstrap capacitor or gate-drive supply, simplifying PCB layout compared to discrete MOSFET half-bridges. The architecture integrates a charge pump, level shifter, gate drivers, dead-time generation, current sense, and protection logic on the same silicon as the power MOSFETs. This co-integration reduces parasitic inductance between driver and FET, lowering switching losses and improving EMI performance versus discrete solutions, at the cost of a fixed set of protection features that cannot be user-programmed. Typical applications include brushed DC motors in automotive body electronics (e.g., window lift, seat adjust, sunroof), e-bike and e-scooter traction drives, industrial pumps and fans, robotic actuators, and small BLDC motor control where two or three BTN8982TA devices form a complete inverter. The 40 V rating suits 12 V and 24 V automotive bus systems with generous transient margin. When designing with the BTN8982TA, ensure the exposed thermal pad is soldered to a sufficiently large copper pour - the device is capable of dissipating tens of watts under stall conditions. Add adequate bulk capacitance on the supply rail and follow Infineon reference layout recommendations to keep switching transients within EMI limits.

What is a half-bridge motor driver? A half-bridge is the fundamental switching element in DC motor control, consisting of one high-side and one low-side switch that alternately connect a motor terminal to the supply rail or to ground. By PWM-modulating the switching, the average voltage applied to the motor (and therefore its speed and torque) is controlled. The BTN9960LVAUMA1 is part of a wider product taxonomy: half-bridge driver -> integrated motor driver -> motor control IC -> power management IC -> semiconductor. Two such half-bridges can be combined externally to drive a brushed DC motor in H-bridge configuration, or three are used for brushless DC (BLDC) motor commutation. Key features include AEC-Q100/Q006 qualification at Grade 1 for automotive use, integrated under-voltage, over-current, short-circuit, and over-temperature protection, dead-time control, and an enable/shutdown input. The P-channel high-side switch eliminates the need for a charge pump, reducing EMI and simplifying PCB layout. Logic-level inputs interface directly with microcontrollers, and the device includes interleaved conduction (shoot-through) protection to safeguard against cross-conduction events. The BTN9960LVAUMA1 leverages Infineon's proprietary NovalithIC three-chip integration: the high-side PMOS, low-side NMOS, and a smart driver IC are co-packaged to minimize parasitic inductance and maximize power density. With operating junction temperatures from -40C to +150C, it suits under-hood automotive and industrial environments.

Key features include a 9.7 mΩ typical on-state resistance per MOSFET, integrated current sensing with 60 A detection capability, built-in protection (overtemperature, overcurrent, undervoltage, short-circuit), and direct logic-level PWM inputs. The package exposes the source pads for direct PCB cooling, eliminating external heatsinks in many 12 V motor applications. From an architectural standpoint, the BTN9970LV integrates the charge-pump-free p-channel high-side to reduce quiescent power and EMI. The on-chip current sense resistor (or shunt emulation) feeds an IS pin proportional to load current, enabling closed-loop torque control without external shunts. Logic inputs are TTL-compatible and accept 3.3 V or 5 V microcontroller signals. Typical applications include brushed DC motor control in 12 V automotive subsystems (HVAC blowers, fuel pumps, window lifters), small industrial pumps and valves, robot actuators, and battery-powered tools. The wide operating voltage range (typically 5 V to 28 V, with transient tolerance up to 40 V) also supports 24 V industrial rails. Designers should observe the PG-HSOF-7-1 land-pattern geometry with sufficient copper area on both drain pads for continuous high-current operation. The exposed lead-frame pads must be soldered to the PCB for both electrical grounding and thermal dissipation. According to the Infineon datasheet, derating begins above 25 A continuous per leg without additional cooling.

A NovalithIC is a fully protected half-bridge or multi-switch power IC that integrates one or more vertical DMOS power stages with on-die charge pump, gate control and diagnostic circuitry. It sits in the broader hierarchy: power MOSFET driver -> half-bridge driver -> motor driver IC -> power management semiconductor. By placing three dice in one package with shared control logic, NovalithIC parts replace discrete H-bridge designs, shrinking PCB footprint, reducing parasitic inductance, and providing built-in protection that would otherwise require external circuitry. Key features include load and GND short-circuit protection, very low quiescent current of 4 µA typical at 25 °C, a small outline thermally-optimized PowerPak package, and the ability to be combined with an additional NovalithIC to create an H-bridge or three-phase bridge.

Designed for low-side driving of relays, solenoids, and valves, it operates from 6V to 28V supplies and provides a regulated hold-current mode that reduces average coil current after the initial pull-in, lowering power dissipation by up to 90% versus direct-drive circuits. What is a solenoid driver IC? A solenoid driver is a specialized power-management IC that switches an inductive load (a solenoid coil, relay, or valve) while controlling the current waveform. It sits hierarchically under motor / motion / ignition drivers, then power-management ICs, then analog semiconductors. By replacing discrete MOSFET+op-amp+comparator circuits with a single integrated controller, a solenoid driver saves PCB area, simplifies firmware, and enables accurate closed-loop current regulation for repeatable mechanical actuation. Key features include a programmable peak-and-hold current profile (with separate peak and hold current set-points), internal PWM generation at a fixed switching frequency, an adjustable dither function for vibration reduction, and integrated thermal shutdown. The device supports 120V/230V AC and 6V-48V DC supply rails when used with appropriate external rectification, making it compatible with industrial control systems as well as 12V/24V automotive loads. Architecturally, the DRV110APWR uses an internal charge-pump to drive an external N-channel MOSFET in low-side configuration, a sense resistor for current feedback, and a digital state machine that autonomously sequences the peak-then-hold profile. The internal 6V to 28V LDO powers the logic, removing the need for an auxiliary rail.

A gate driver unit is a power-management IC that translates low-voltage logic signals from a microcontroller into the high-current gate signals required to switch external power MOSFETs in a three-phase inverter. Within the power-electronics hierarchy, the GDU sits between the MCU and the MOSFET bridge, providing gate charge amplification, protection logic, and system diagnostics for brushless DC (BLDC) and PMSM motor drives. Key features include high gate drive capability (3.5-A source / 4.5-A sink peak) enabling fast switching of large parallel MOSFET arrays, a highly efficient bootstrap architecture for the high-side supply, and 90-V transient overvoltage support that protects against load-dump-style events on 48-V rails. Digital I/O pins withstand up to 75-V absolute maximum ratings, protecting the device against 12-V supply overvoltage events. The DRV3255-Q1 integrates a highly configurable Active Short Circuit (ASC) function that short-circuits selected external MOSFETs in response to system faults, eliminating external transistors and control logic. According to TI, it was the industry's first 48-V three-phase BLDC driver to integrate active shorting on both high and low sides. Wide monitoring and diagnostic capability supports robust, functional-safety-oriented motor drive system design, making it well suited to ASIL-oriented architectures in electrified powertrain systems. Typical applications include 48-V belt starter generators (BSG), motor generators for mild-hybrid electric vehicles (MHEV), e-turbo and e-compressor drives, and 48-V high-power traction accessories. TI reference design SLVAF39A covers driving parallel MOSFETs with this device for 350-A class output stages. Design consideration: verify bootstrap capacitor sizing against the total gate charge of the selected MOSFETs, and confirm that the ASC pin configuration matches the required short-circuit strategy before finalizing the PCB layout.

DRV8231 - 35V 3.7A H-Bridge Motor Driver | Texas Instruments
The Texas Instruments DRV8231 is a 35-V, 3.7-A brushed DC motor driver with integrated current regulation, supplied in a compact 8-pin WSON (DSG, 2x2 mm) package. It operates from a 4.5-V to 33-V supply rail and integrates four N-channel MOSFETs forming an H-bridge with a typical RDS(on) of 600 mOhm (including one high-side and one low-side FET). A brushed DC motor driver is a type of motor controller IC that switches power to a DC motor using an H-bridge of transistors, enabling forward, reverse, brake, and coast control. Within the power management IC hierarchy, motor drivers sit between logic-level microcontroller outputs and the power stage, and integrated H-bridge drivers like the DRV8231 combine gate drive, power FETs, charge pump, and protection in a single device. Key features include integrated current regulation with programmable current limit via the ILIM pin, a charge pump that supports 100% duty cycle operation and full N-channel H-bridge efficiency, and low-voltage logic inputs compatible with 3.3-V and 5-V controllers. Two logic inputs (PWM interface on the DRV8231D variant, PH/EN interface on the DRV8231A variant) control the bridge states, minimizing MCU pin usage and firmware complexity. Technically, the DRV8231 family offers pin-to-pin scalable RDS(on) and supply voltage options, allowing designers to support various loads and rails with minimal PCB changes. Integrated protection includes undervoltage lockout, overcurrent protection, and thermal shutdown, reducing external component count and board area compared to discrete MOSFET bridge solutions. Typical applications include brushed DC motor control in printers, small appliances, actuators, robotics, factory automation systems, and consumer electronics, where the compact 2x2 mm WSON-8 package fits space-constrained designs and integrated current regulation protects the motor and PCB traces without an external sense resistor network. When designing with the DRV8231, set the current limit using the ILIM pin resistor per the datasheet equation and provide a solid power ground plane under the exposed pad, since bridge conduction losses scale with the 600 mOhm typical RDS(on) at higher load currents.

The Texas Instruments DRV8242SQRHLRQ1 is an automotive-qualified 40V, 6A H-bridge motor driver with integrated high-side current sensing and feedback, housed in a 20-pin VQFN (RHL) package measuring 3.5 x 4.5 x 0.9 mm and rated for operation from -40C to +125C. An H-bridge motor driver is a power management IC that controls the direction, speed, and braking of a DC motor by switching four internal power transistors in complementary pairs. H-bridge drivers sit within the motor driver family of the broader power management IC hierarchy, bridging the gap between low-voltage logic controllers and the inductive loads of brushed DC motors, stepper motors, and actuators used across automotive and industrial systems. Key features include the integrated 40V-rated N-channel H-bridge, an integrated charge pump regulator for high-side gate drive, and on-chip current sensing with regulation that eliminates the need for external sense resistors. Control is provided through PWM or SPI interfaces, and a low-power sleep mode minimizes quiescent current for always-on automotive modules. The DRV8242-Q1 family shares an identical pin function across variants with scalable RON (on-resistance) to match different load currents, allowing designers to scale power capability without PCB redesign. Integrated protection circuitry covers overcurrent, thermal, and supply fault conditions, and the current-proportional output feeds motor current data back to the microcontroller for closed-loop control and diagnostics. Typical applications include automotive brushed DC motor modules such as pumps, fans, actuators, HVAC dampers, seat adjusters, and door latches, as well as industrial motion control where a compact 4.5V to 35V supply range and 6A continuous current are required. When designing with this device, exploit the integrated current-sense regulation to remove external shunt resistors, but ensure the VQFN exposed pad is soldered to an adequate PCB thermal plane to dissipate conduction losses at full 6A load. Verify that the supply path tolerates inductive kick-back beyond the 40V rating during aggressive PWM braking.

An H-bridge driver is a power management IC that controls the direction, speed, and braking of DC motors and other inductive loads by switching four bridge arms in controlled combinations. Within the power electronics hierarchy, the DRV8243-Q1 belongs to the integrated motor driver family: a monolithic device combining gate drive, power stage, current sensing, diagnostics, and protection in a single package, eliminating the need for discrete MOSFETs and gate drivers. Key features include a 40 V absolute maximum supply rating supporting 12-V automotive battery systems with load-dump headroom, up to 12 A of current capability from an integrated N-channel H-bridge on a BiCMOS high-power process, and high-side current sensing with regulation plus a current-proportional analog feedback output. The SPI (SQ) control interface allows configuration of off-state diagnostics, current regulation thresholds, slew-rate control, and detailed fault reporting, enabling predictive maintenance and functional-safety architectures. The DRV824x-Q1 family is fabricated on a monolithic BiCMOS high-power process that delivers excellent power handling and thermal performance. The family shares an identical pin function across members with scalable RON, so designers can trade current capability against cost without a PCB respin. A low-power sleep mode minimizes quiescent battery drain, and an integrated charge pump guarantees full enhancement of the high-side N-channel FETs across the supply range. Typical applications include automotive body and comfort functions such as power liftgates, power seats, window lifters, sunroof and pump actuators, as well as industrial 12-V brushed-DC motor drives requiring rich diagnostics. The integrated current-sense amplifier with proportional output removes the external sense resistor in many designs, saving board area and improving efficiency. Design consideration: because the bridge power FETs are integrated, thermal design centers on PCB copper area under the power pad; estimate conduction losses as I^2 x RON per arm and verify junction temperature against the AEC-Q100 Grade 1 ambient range.

DRV8256ERGER - 50V 8A H-Bridge Motor Driver with Smart Tune | TI
The Texas Instruments DRV8256ERGER is a 50-V, 8-A H-bridge motor driver with integrated current sense and Smart Tune technology, delivered in a 24-pin VQFN (RGE) package measuring 4x4 mm. It supports bipolar control through PH/EN inputs (no IN1/IN2 PWM pins), integrates two N-channel power MOSFET half-bridges plus low-side current sensing, and operates from a single supply of 4.5 V to 48 V. The device is qualified for -40C to +125C ambient operation and includes comprehensive protection: VM undervoltage lockout, charge-pump undervoltage, overcurrent protection, overtemperature shutdown, and open-load detection. An H-bridge motor driver is a type of brushed DC or stepper motor driver that uses four switching elements arranged in an H topology to drive current in either direction through a single winding. H-bridge drivers belong to the broader family of motor drivers (brushed DC, stepper, BLDC) which in turn fall under power management ICs and discrete semiconductor categories. By integrating the FETs, gate drivers, current sense amplifier, and protection logic in one package, the DRV8256ERGER replaces discrete implementations that would otherwise require dozens of components. Key features include 8-A peak H-bridge output current (derated to ~4.5 A RMS depending on PCB copper area), integrated current sensing that eliminates an external sense resistor, Smart Tune technology that automatically adjusts dead time and decay mode to minimize audible motor noise and current ripple, and a 1.5 A peak gate-drive flyback clamp for inductive loads. The device supports both PWM (PH/EN) and independent half-bridge control modes. The architecture pairs a charge pump (for the high-side gate drive) with a current-shunt monitor on each low-side FET, feeding the integrated sense amplifier whose output appears on the SO pin as an analog voltage. Smart Tune combines four decay modes - slow decay, fast decay, mixed 30%, mixed 60% - and selects them dynamically based on motor current to suppress ripple current and acoustic noise without firmware tuning. Typical applications include brushed DC motors in robotic vacuums, small home appliances, e-bike valve actuators, industrial pumps, and consumer fans. The wide 4.5 V to 48 V supply range covers USB, single-cell Li-ion, lead-acid 12 V, and industrial 24 V / 36 V / 48 V rails. The integrated sense amplifier is particularly valuable in closed-loop torque or current control. When designing with the DRV8256ERGER, place the VM bulk capacitor as close to pins 5-6 and 19-20 (VM/GND) as possible. The exposed thermal pad (pin 24) must be soldered to a top-side copper pour of at least 1 cm^2 to stay within thermal limits at 8 A peak loads. Use 100 nF + 10 uF bypass directly on VM, and add a TVS diode across the motor terminals if the application includes long cable harnesses to absorb flyback transients.

DRV8301DCAR - 65V 3-Phase Gate Driver with Buck Regulator & SPI | Texas Instruments
The Texas Instruments DRV8301DCAR is a 65-V maximum three-phase gate driver with integrated dual current shunt amplifiers, a buck regulator, and an SPI interface, housed in a 56-pin HTSSOP (DCA) package with PowerPAD. It is designed to drive six N-channel power MOSFETs (three half-bridges) for sensored or sensorless brushless DC (BLDC) and permanent-magnet synchronous motor (PMSM) applications. The gate driver section supports a wide 8 V to 60 V motor supply range, while the integrated 1.5 A synchronous buck converter produces an auxiliary 3.3 V or 5 V rail for companion MCUs. A three-phase gate driver is a power-management IC that converts low-power PWM control signals from a microcontroller into the high-current gate-drive signals required by the high-side and low-side MOSFETs of each inverter leg. It sits between the digital control domain (logic-level PWMs) and the high-power motor domain (tens of volts and tens of amps), and is therefore classified within the broader hierarchy of motor drivers > motion controllers > power management ICs > semiconductor. By integrating the gate drive, current sensing, and auxiliary supply, the DRV8301 collapses what would otherwise be three separate ICs into a single device, simplifying BLDC inverter design. Key features include: a programmable 5 mA to 60 mA gate-drive current with adaptive dead-time insertion to prevent shoot-through; integrated dual current-shunt amplifiers with adjustable gain (10/20/40/80 V/V) and 5 µs settling time for FOC torque control; a 1.5 A, 0.8 V to 8.5 V adjustable buck regulator; SPI-configurable protection (overcurrent, overtemperature, undervoltage, gate-drive fault); and an operating temperature range of -40 °C to +125 °C. The HTSSOP-56 PowerPAD package offers θJA ≈ 31 °C/W when the exposed pad is soldered to sufficient copper area. Architecture-wise, the DRV8301 pairs a charge-pump-derived high-side bias supply with a bootstrap-capacitor-per-phase design, allowing 100% duty-cycle operation of the high-side FETs without external floating rails. The current-sense amplifiers use continuous-time chopper-stabilized op-amps to minimize offset drift, which directly improves the low-speed torque accuracy of sensorless FOC schemes. The SPI port allows in-system tuning of dead-time, current-sense gain, OC threshold, and buck VOUT, enabling firmware-controlled optimization for different MOSFET choices. Typical applications include drone (UAV) ESCs, e-bike / e-scooter traction drives, cordless power tools, HVAC fans and pumps, and small industrial servo drives. The DRV8301 is also the gateway IC on TI's well-known DRV8301-69M-KIT reference design for InstaSPIN-FOC motor control. When designing with this part, follow TI's MOSFET short-circuit ruggedness guidance and lay out the PowerPAD with at least 1 in² of 2-oz copper to keep the gate-driver junction within safe limits. This page synthesizes distributor pricing, drop-in alternatives, and application-focused design notes that complement the manufacturer datasheet. The DRV8301DCAR is specified in TI's datasheet revision F, available from ti.com/lit/ds/symlink/drv8301.pdf.
DRV8303DCAR - 65V 3-Phase Gate Driver w/ Dual CSA & SPI | TI
The Texas Instruments DRV8303DCAR is a 65-V maximum three-phase gate driver IC for BLDC and PMSM motor-drive applications, integrating three half-bridge pre-drivers, two current-shunt amplifiers, and an SPI-configurable register set in a 48-pin HTSSOP (DCA) package with PowerPAD. The device delivers up to 1.7-A peak source and 2.3-A peak sink gate-drive current per channel, supporting external N-channel MOSFETs in 6-to-600 V motor systems. A three-phase gate driver, also called a pre-driver or brushless DC motor driver, sits between an MCU/controller and the high-current power stage. It converts low-current PWM logic signals into high-current gate-drive waveforms capable of rapidly switching N-channel MOSFETs in a three-phase bridge, while providing critical protection features (dead-time insertion, bootstrap management, fault reporting) that the controller cannot deliver alone. Within a motor-control system it sits between the microcontroller (such as a C2000 or Sitara) and the three-phase inverter bridge. Key features include a wide 6-V to 60-V single-supply input, integrated bootstrap diodes with trickle-charge support, dual bidirectional current-shunt amplifiers with adjustable gain (5/10/20/40 V/VIA), SPI for configuring gain, dead time, and OC protection thresholds, and a 1.8-V/3.3-V compatible logic interface. Protection features include undervoltage lockout (UVLO) on both the gate-drive and bootstrap rails, overcurrent protection with configurable thresholds, thermal warning and shutdown, and a fault-output flag. The DRV8303 uses a bootstrap gate-driver architecture with an internal charge pump to support 100% duty-cycle PWM, eliminating the need for a separate isolated supply for the high-side drivers. The integrated dual current-shunt amplifiers save board space and BOM by removing the need for external op-amp CSA circuits in sensored and sensorless FOC applications. Typical applications include three-phase BLDC/PMSM motor drives (e.g., drones, e-bikes, robotics, industrial fans, pumps, and CNC spindles), EV traction auxiliaries, and 48-V telecom/server cooling fans. The SPI interface makes it particularly suited to digital motor-control loops using field-oriented control (FOC) or trapezoidal commutation. When designing with this device, choose external N-channel MOSFETs whose total gate charge (Qg) is well below 50 nC to stay within the 1.7-A source / 2.3-A sink envelope, and place the bootstrap capacitors (typically 100 nF ceramic) as close to the BSTx and SHx pins as possible to minimize parasitic inductance. Thermal management: the PowerPAD must be soldered to a sufficient copper area (≥1 in²) to keep junction temperature within the 150 °C shutdown limit at high ambient.

The Texas Instruments DRV8308RHAR is a 42-V maximum sensored sinusoidal control 3-phase brushless DC (BLDC) gate driver with SPI, housed in a 40-pin VQFN (RHA) 6x6 mm package. It controls sensored BLDC motors with a configurable gate-drive current of 10 mA to 130 mA and operates from 8.5 V to 32 V, with 42-V absolute maximum tolerance on the motor supply rail. What is a BLDC gate driver? A BLDC (brushless DC) gate driver is an integrated circuit that interfaces between a low-power microcontroller and the high-current three-phase inverter that drives a brushless DC motor. The gate driver sits in the power-management hierarchy below the MCU and above the power MOSFETs, providing level shifting, dead-time insertion, gate-drive strength control, and protection features (undervoltage, overcurrent, thermal) so the MCU does not have to handle high-current switching directly. Key features of the DRV8308RHAR include three Hall-sensor inputs for rotor-position feedback, an SPI interface for command and telemetry, configurable gate-drive current from 10 mA to 130 mA per MOSFET, integrated commutation logic, a closed-loop speed controller using CLKIN/FG, and support for both sensored trapezoidal and sensorless (BEMF) commutation. The 40-pin VQFN (RHA) package provides a low-thermal-resistance path for dissipating the gate-drive losses. The architecture combines a precision analog front-end for Hall sensors with a digital speed-control loop and three half-bridge predrivers. The configurable gate-drive current allows the designer to tune switching losses versus EMI for a given power MOSFET. An SPI port enables in-system configuration of current limits, PWM frequency, commutation mode, and read-back of fault status. According to TI product literature, the device is designed for fast closed-loop speed control with minimal MCU overhead. Typical applications include brushless DC fan and pump drives, e-bike and e-scooter traction controllers, cordless power tools, small HVAC blowers, and white-goods appliance motors. The sensored sinusoidal mode produces low acoustic noise and torque ripple, which is critical for fans and pumps used in noise-sensitive environments. When designing with the DRV8308RHAR, ensure the 8.5 V to 32 V motor supply is decoupled with low-ESR ceramic capacitors placed close to the VM and PGND pins. Select external N-channel MOSFETs with Vds ratings comfortably above the maximum motor supply, and program the gate-drive current via SPI to balance switching loss and EMI for the chosen MOSFET package. This page synthesizes current distributor pricing, verified drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, giving engineers a single source for parametric data, sourcing options, and PCB-layout guidance.
DRV8308RHAT - 42V Sensored BLDC Gate Driver w/ SPI | Texas Instruments
The Texas Instruments DRV8308RHAT is a 42-V max sensored sinusoidal control, 3-phase brushless DC (BLDC) gate driver with SPI, housed in a 40-pin VQFN (RHA) package measuring 6x6 mm. It functions as a pre-driver that controls the gates of six external N-channel MOSFETs with a configurable gate-drive current of 10 mA to 130 mA, enabling optimized switching characteristics across a wide motor-speed range. Motor commutation is driven by Hall sensor inputs, and once a consistent rotor speed is reached the DRV8308 transitions from sensored trapezoidal commutation to sensorless sinusoidal commutation using a single Hall sensor. A brushless DC (BLDC) motor controller is an integrated circuit that sequences power to the three stator windings of a brushless motor in the correct order, converting DC bus voltage into rotating magnetic fields. Within the broader product hierarchy, BLDC motor controllers belong to motor-driver ICs, which are a subset of motion control and ignition ICs within power management. The DRV8308 specifically sits in the gate-driver (pre-driver) category because it does not contain integrated power FETs; instead, it controls external MOSFETs, allowing designers to scale the power stage for higher current motors than integrated-driver ICs can support. Key specifications include an 8.5 V to 32 V (42 V abs max) supply-voltage range, integrated SPI interface for parameter tuning, configurable gate-drive current (10 mA to 130 mA), cycle-by-cycle current limit, and built-in protection including undervoltage lockout, overcurrent protection, and thermal shutdown. The device supports both sensored and sensorless sinusoidal control, enabling smooth low-speed torque and quiet high-speed operation. Hall-sensor inputs are configurable for 60-degree or 120-degree mechanical placement. Typical applications include cordless power tools, e-bikes and electric scooters, drones and multicopter flight controllers, CPU cooling fans, pumps, and small HVAC blowers. The wide 8.5-32 V supply range is compatible with both single-cell Li-ion (with boost) and multi-cell Li-ion packs up to 8S, while the configurable gate drive allows pairing with low-side MOSFETs of various RDS(on) and Qg values to optimize efficiency and EMI for each motor platform. When designing with the DRV8308RHAT, ensure the SPI pull-up resistor on the SDATA line is sized correctly for the selected clock rate, and that the bootstrap capacitors are placed close to the BSTx pins with short traces to minimize switching losses and ringing. The thermal pad of the VQFN-40 must be soldered to a copper pour of at least 1 square inch for reliable operation at sustained high gate-drive currents. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, helping engineers select and source the DRV8308RHAT with confidence for BLDC motion-control designs.

Each half-bridge can be controlled independently, enabling flexible motor control schemes such as trapezoidal or sinusoidal commutation. The device also includes a current-sense output that can be used for closed-loop current control, enhancing system performance. Typical applications include three-phase brushless-DC motor drives for fans, pumps, and robotics, as well as solenoid drivers and other inductive loads. The wide voltage range and high current capability make it suitable for both 12V and 24V systems, common in industrial and automotive environments. When designing with the DRV8313PWPR, ensure adequate PCB copper area for heat dissipation, especially at high currents. The exposed thermal pad should be soldered to a large ground plane to improve thermal performance. Additionally, place decoupling capacitors close to the power supply pins to minimize voltage transients.
