- AEC-Q100 qualification (vs MC33887)
Design Notes
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.
