The AEC-Q100 qualification ensures reliability in harsh automotive environments, and the diagnostic output enables fault detection for each channel, improving system diagnostics. The wide supply voltage range (4V-28V) accommodates both 12V and 24V vehicle systems, and the low standby current (0.5uA) helps reduce battery drain when the vehicle is off. In a typical BCM, the VND7050AJTR is placed between the battery rail and the load, with the enable input connected to a microcontroller GPIO and the diagnostic output fed back to an ADC or digital input for status monitoring. The device's built-in protection against overcurrent, overtemperature, and short-circuit conditions ensures safe operation under fault conditions, reducing the need for external protection components. When driving inductive loads like relays or motors, an external freewheeling diode is recommended to clamp voltage spikes. The PowerSSO-16 package with exposed pad provides good thermal performance, allowing continuous operation at high currents with adequate PCB copper area.

Design Notes
The PowerSSO-16 package has a thermal resistance of 40C/W (junction-to-ambient). At 9A continuous current with 70mOhm RDS(on), power dissipation is approximately 5.7W per channel. Ensure adequate PCB copper area (at least 1 square inch) for heat dissipation. For high ambient temperatures, consider a heatsink or forced air cooling.
Place the VND7050AJTR close to the load to minimize trace inductance. Use wide traces for high-current paths (OUT1, OUT2, VCC, GND) to reduce resistance and inductance. Connect the exposed pad to a large ground plane for thermal and electrical performance. Add a 100nF ceramic capacitor close to the VCC pin for high-frequency decoupling.
For inductive loads, always use an external freewheeling diode across the load to clamp voltage spikes during turn-off. The diagnostic output is open-drain and requires a pull-up resistor (typically 10kOhm) to the microcontroller's supply voltage. Do not exceed the absolute maximum supply voltage of 28V. Ensure the enable input is not left floating; use a pull-up or pull-down resistor as needed.
