AM9468
Description
Pin Assignments The AM9468 is a high performance ultra low noise single phase (single-coil) brushless direct current (BLDC) fan and motor driver. The integrated full-bridge driver output stage uses a BTL linear driver architecture to minimize audible switching noise and electromagnetic interference (EMI) providing a low noise solution.
