6EDL7141XUMA1 - 60V 3-Phase BLDC Gate Driver IC | Infineon
The Infineon 6EDL7141XUMA1 is a three-phase, half-bridge-based smart gate driver IC designed for battery-supplied BLDC and PMSM motor control. It integrates three half-bridge drivers capable of sourcing/sinking 1.5 A peak gate current, operates from a 5.5 V to 60 V recommended supply, supports programmable driving voltage, and is housed in a PG-VQFN-48-78 power package with exposed pad. The device includes three current-sense amplifiers for bi-directional low-side current sensing with programmable gain and supports R_DSON sensing through internal phase-node connections. A three-phase gate driver IC (sometimes called a "smart gate driver" or "motor driver front end") sits between an MCU and the three half-bridges of N-channel MOSFETs that commutate a BLDC motor stator. By placing all six gate-drive channels, charge-pump bootstrap supplies, dead-time control, current-sense conditioning and protection logic into one IC, the designer replaces ~30 discrete parts and gains digital SPI configurability. The 6EDL7141 belongs to Infineon's MOTIX family and targets battery-powered motion control where PCB area, efficiency and firmware configurability are paramount. Key differentiating features include 1.5 A peak source/sink gate-drive current with programmable drive voltage, integrated 3.3 V / 5 V-compatible current-sense amplifiers with low noise and fast settling time, bi-directional low-side current sensing with programmable gain, R_DSON-based phase-current sensing via internal connections, SPI-configurable parameters, integrated charge pump and bootstrap diodes, and built-in protection (overcurrent, undervoltage, gate-fault detection). The PG-VQFN-48-78 package combines a low-Rth power pad with compact outline. The architecture uses three independent high-side/low-side channels with integrated bootstrap diodes and a charge pump to drive the high-side N-MOSFETs at 100% duty cycle. Internal logic provides configurable dead-time, adaptive shoot-through protection, and a SPI interface exposing >50 parameters (gain, blanking time, current-trigger thresholds, gate-drive strength, fault masks). Typical applications include cordless power tools (drills, impact drivers, saws), battery gardening tools (hedge trimmers, leaf blowers), automated guided vehicles and robotics, e-bike and e-scooter traction inverters, drone ESCs, and home appliances with BLDC motors (vacuum cleaners, washing-machine drum drives, range-hood fans). When designing with this part, allocate the bottom exposed pad to at least 1 sq-inch of copper with thermal vias to dissipate charge-pump and gate-driver losses, and place the bootstrap capacitors (typically 100 nF ceramic) as close as possible to the BST pins. Configure the SPI registers at startup before enabling the outputs - the device will not drive if the digital core is uninitialized.

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.

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.

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.

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.

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 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.
