AH5772 Overview
The AH5772 is a single chip solution for driving single-coil brushless direct current (BLDC) fans and motors. The integrated full-bridge driver output stage uses soft switching to minimize audible switching noise and electromagnetic interference (EMI) providing a low noise solution. Pin Assignments (Front View) To simplify system circuit and minimize external ponents, the device integrates a stable high sensitivity...
