Selection Guide

Choose the VNHD7012AY when you need a high-current (12A) H-bridge driver with AEC-Q100 qualification for automotive or industrial applications. If your load current is below 10A and cost is a concern, the VNH7100A offers a lower-cost alternative with the same package and pinout. For applications requiring even higher current (up to 30A), consider the VNH5019A, but verify pin compatibility. The DRV8876 from Texas Instruments is a cross-brand alternative with lower current capability and no AEC-Q100 qualification, making it suitable only for non-automotive, lower-power applications. Always verify pinout and electrical parameters before substitution.

Design Notes

The PowerSSO-36 package has an exposed thermal pad that must be soldered to a large copper area on the PCB. For 12A continuous operation, ensure at least 2 square inches of copper on the top and bottom layers, connected with thermal vias. The thermal resistance (theta_JA) is approximately 25 C/W with proper layout, allowing up to 5W dissipation without external heatsink.

Place 100nF ceramic capacitors close to the VS and VCC pins to decouple high-frequency noise. Use a 10uF electrolytic capacitor on the VS pin to handle current transients. The current sense output (CS) should be filtered with a 1kOhm resistor and 10nF capacitor to reduce switching noise. Keep the PWM and logic input traces short and away from high-current paths.

Do not exceed the absolute maximum supply voltage of 28V, as this can damage the device. Ensure the logic inputs are not left floating; use pull-down resistors to define a known state. The current sense output is only valid when the device is in normal operation; during fault conditions, it may be clamped. Always read the diagnostic output to distinguish between overcurrent, overtemperature, and undervoltage faults.
