VNHD7012AY - Automotive H-Bridge Motor Driver | STMicroelectronics
MPN： VNHD7012AY ✓ 啟用中VNHD7012AY 概覽
An H-bridge motor driver is a power management IC that controls the direction and speed of a DC motor by selectively switching four transistors in an 'H' configuration. It is a critical component in automotive systems such as power windows, seat adjusters, steering column actuators, and HVAC actuators. The VNHD7012AY belongs to the VIPower M0-7 family, which combines a true PowerMOSFET with intelligent signal and protection circuitry on a single die, simplifying design and improving reliability.
Key features include a wide operating voltage range of 4V to 28V, a maximum output current of 38A (as referenced in the EV-VNHD7012AY reference design), and a low ON-state resistance that minimizes power dissipation. The device provides comprehensive protection including load current limitation, overtemperature shutdown, overvoltage clamp, and loss of ground protection. It also features a PWM input for speed control and a diagnostic output for fault detection.
The VNHD7012AY uses STMicroelectronics' proprietary VIPower technology, which integrates a vertical power MOSFET with intelligent control circuitry. This architecture enables efficient switching, low quiescent current, and robust protection against automotive transients. The PowerSSO-36 package, with its exposed pad, provides a thermal resistance suitable for high-current applications when properly connected to a PCB copper area.
Typical applications include automotive DC motor driving for power windows, sunroofs, seat adjustment, steering column tilt/telescope, and HVAC actuators. The device is also suitable for industrial DC motor control where 12V or 24V supplies are used. Its high current capability and protection features make it ideal for driving motors that require bidirectional control and PWM speed regulation.
When designing with the VNHD7012AY, ensure adequate PCB copper area for thermal management, especially at high output currents. The two external low-side MOSFETs must be selected to match the motor's current and voltage requirements, and proper gate drive connections must be made to the device's gate driver outputs.

設計說明
The VNHD7012AY is housed in a PowerSSO-36 package with an exposed pad. For high-current applications (e.g., 38A), ensure the exposed pad is soldered to a large copper area on the PCB to dissipate heat effectively. Use thermal vias to connect the pad to inner and bottom layers. The thermal resistance can be reduced by increasing the copper area, which is critical for maintaining junction temperature within safe limits.
Place the external low-side MOSFETs close to the VNHD7012AY to minimize gate drive loop inductance. Use separate ground planes for power and logic to reduce noise coupling. Decouple the VCC pin with a 100nF ceramic capacitor and the VS pin with a 10uF electrolytic capacitor placed near the device. Ensure the gate drive outputs (GATE1, GATE2) have proper routing to the MOSFET gates with minimal trace length.
Do not exceed the maximum supply voltage of 28V, as this can damage the device. Ensure the external low-side MOSFETs are rated for the motor's stall current and the supply voltage. The PWM frequency should be selected based on the motor's characteristics and the MOSFET's switching losses. Avoid operating the device without a proper heatsink or copper area at high currents, as this can lead to overtemperature shutdown.
