Pin Function Description
Power Ground. Return pin for high currents flowing in pin 24 (V_CCP).
V_CC Low Side FET Driver. Connect this pin to the gate of an N-channel MOSFET
for synchronous operation. The trace from this pin to the MOSFET gate should be
<0.5".
Power V_CC. For all FET drivers. Connect to system 12V supply through a 33Ω, and
decouple with a 1µF ceramic capacitor.
