AH5773 Description
The AH5773 is a high performance, 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. To simplify circuit design and minimize external ponents, the device integrates a stable high sensitivity Hall-effect...
