AM9468 Product details

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.For system flexibility the motor speed can be controlled by either an external PWM signal or by a DC voltage or from a thermistor network.Based on the input si
