VNH7100BASTR Übersicht
An H-bridge motor driver is a power management IC that controls the direction and speed of a brushed DC motor by selectively activating four switches in an H configuration. It belongs to the broader hierarchy of motor drivers -> motion controllers -> power management ICs -> semiconductors. The VNH7100BASTR integrates the full H-bridge and the gate-drive/protection logic in one package, eliminating the bulk of discrete MOSFET bridges, gate drivers, and current-sense amplifiers.
Key features include a 60 mΩ typ. on-resistance per high-side switch that minimizes conduction loss, PWM control up to 20 kHz for precise speed regulation, and a comprehensive protection suite: undervoltage lockout, overvoltage clamp, thermal shutdown with auto-restart, and load current limitation. A dedicated diagnostic feedback pin reports fault conditions to the host MCU. The PowerSSO-16 exposed pad provides a low thermal resistance path, supporting 12 A continuous operation with proper PCB copper.
Typical applications include 12 V automotive brushed DC loads such as power window lifters, seat adjusters, mirror fold actuators, HVAC flaps, and door lock motors. The wide 4 V to 28 V supply range also suits industrial 24 V brush DC drives and battery-powered robotics where a single-IC H-bridge simplifies BOM and PCB area.
When designing with this device, dedicate at least 1 sq in of top-side copper to the exposed pad and stitch a 4×4 thermal via array to the inner/inner-outer copper planes to keep junction temperature in spec. Place a 100 nF X7R ceramic bypass within 2 mm of the VCC pin and a bulk 47 µF electrolytic at the motor connector. Use a gate resistor or RC snubber on the PWM input if long MCU traces cause ringing above 5 MHz.

Typische Anwendungen
VNH7100BASTR ist geeignet für 6 Anwendungs: Automotive Power Window Lifter, Power Seat Adjuster Motor Drive, Side Mirror Fold Actuator, HVAC Blend/Flap Actuator, Door Lock Motor Drive, Industrial 24 V Brushed DC Drive.
Automotive Power Window Lifter
The VNH7100BASTR's 12 A continuous rating directly supports window-lift motor stall currents, and its 4 V lower supply bound survives 12 V cold-crank events. AEC-Q100 qualification allows the part to ship in OEM door-module PCBs without requalification. Place the H-bridge between the 12 V battery rail and the window motor, and use the diagnostic pin to feed back fault status to the body-control MCU.
Empfohlen
Power Seat Adjuster Motor Drive
Seat-position motors require bidirectional current up to ~10 A and PWM speed control for soft-start comfort positioning. The VNH7100BASTR's 20 kHz PWM capability and 60 mΩ high-side RDS(on) keep dissipation under 1 W per switch during typical seat travel. The exposed PowerSSO-16 pad dissipates waste heat into the seat-module chassis ground plane, eliminating an external heatsink.
Empfohlen
Side Mirror Fold Actuator
Mirror-fold motors draw 2-4 A peak during the 1-2 second fold cycle, well within the VNH7100BASTR's 12 A envelope. The integrated overvoltage clamp protects the H-bridge from 24 V jump-start transients on the body harness. The device's diagnostic output signals fault conditions back to the BCM, enabling OBD-compliant fault logging for premium mirror modules.
Empfohlen
HVAC Blend/Flap Actuator
HVAC flap motors operate at low duty cycle with 1-3 A average current, but require VDC+ regulators for continuous position hold. The VNH7100BASTR's PWM control and current-limit features make it suitable for stepping the flap through precise angles while reporting stall conditions. AEC-Q100 qualification matches the under-dash thermal environment of HVAC control modules.
Empfohlen
Door Lock Motor Drive
Door-latch actuators need a short 10-15 A inrush pulse followed by ~2 A holding current. The VNH7100BASTR handles the inrush on its 12 A continuous rating with the current-limit circuit clamping stall events. The integrated thermal shutdown protects against prolonged stall conditions, and the PowerSSO-16 exposed pad dissipates the inrush energy without an external heatsink.
Empfohlen
Industrial 24 V Brushed DC Drive
On a 24 V industrial bus, the VNH7100BASTR's 28 V upper supply bound provides margin against rectified 24 V transformer ripple. The VIPower M0 protection suite rejects inductive kickback when the motor commutates, eliminating external flyback diodes and shrinking the BOM. Industrial enclosures with 50 °C ambient are tolerated thanks to the -40 °C to +150 °C junction range.

Wichtigste Unterscheidungsmerkmale
- 12 A continuous rating in PowerSSO-16 exposed-pad package (vs. VNH7070BASTR)
- Latest 'B' silicon revision (vs. VNH7100ASTR)
- AEC-Q100 automotive qualification (vs. DRV8873HPWPR)
Designhinweise
Estimated: at 12 V supply, 12 A continuous output with a stalled motor (100% duty), the VNH7100BASTR dissipates approximately 60 mΩ × 12 A × 2 switches ≈ 17 W. A PowerSSO-16 with a 4×4 thermal via array on a 1 sq in copper pour keeps theta_JA under 30 °C/W, holding Tj below 150 °C in 50 °C ambient. At lower duty cycles (e.g. seat travel <2 s), much smaller copper areas are adequate.
Place a 100 nF X7R ceramic bypass within 2 mm of the VCC pin to suppress the high-side driver switching transients. Add a 47 µF electrolytic bulk capacitor at the motor connector to absorb motor commutation energy. Stitch a 4×4 thermal via array (0.3 mm drill, 0.6 mm pad) under the exposed pad and tie the inner planes to a clean ground island for best power dissipation.
Do not float the EN pin - tie it to VCC through a 10 kΩ pull-up if unused, or to the MCU GPIO if controlled. Avoid routing the motor wires parallel to the PWM logic traces for more than 25 mm; keep at least 5 mm spacing or a ground guard trace to prevent dv/dt noise from coupling into the IN1/IN2 logic. Always observe the motor current rating versus the H-bridge 12 A continuous limit; peak inrush above 12 A will trigger the current-limit circuit and may stall the application.
