The VNH7100BASTR also features a diagnostic output that reports fault conditions, enhancing system reliability.
The VNH7100BASTR uses STMicroelectronics' VIPower M0 technology, which integrates the control logic and power stage on a single die. This architecture provides robust performance in harsh automotive environments, with an operating temperature range of -40Β°C to +150Β°C. The device is AEC-Q100 qualified, ensuring reliability for automotive applications.
Typical applications include automotive DC motor control for power windows, mirrors, seat adjusters, and HVAC actuators. It is also suitable for industrial automation, robotics, and other battery-powered motor control systems. The wide supply voltage range and high current capability make it a versatile choice for various motor control applications.
When designing with this device, ensure adequate PCB copper area for heat dissipation, especially at high currents. The exposed pad should be soldered to a thermal via array to improve thermal performance. Additionally, place a 100nF ceramic capacitor close to the supply pins for decoupling.

Key Differentiators
- Higher continuous current rating (12A) compared to VNH7070BASTR (10A) (vs VNH7070BASTR)
- AEC-Q100 qualified for automotive applications (vs VNH7100ASTR)
- Low on-resistance (60mOhm) improves efficiency (vs VNH5019)
Design Notes
At 12A continuous current, power dissipation can be significant. With 60mOhm on-resistance, each switch dissipates about 8.6W. The PowerSSO-16 package with exposed pad requires a thermal via array and adequate copper area to keep junction temperature below 150Β°C. Use at least 2 square inches of copper on the PCB for heat spreading.
Place a 100nF ceramic capacitor close to the VS and VCC pins for decoupling. Use a 10uF electrolytic capacitor on the VS pin for bulk energy storage. Ensure the exposed pad is soldered to a thermal pad with multiple vias to improve thermal performance. Keep high-current traces short and wide to minimize inductance and resistance.
Do not exceed the absolute maximum supply voltage of 28V. Ensure the enable pin is properly driven to avoid unintended operation. The diagnostic output is open-drain and requires a pull-up resistor. When driving inductive loads, ensure proper freewheeling diodes are used to prevent voltage spikes.
