AM9469 Datasheet Low Noise Single Phase Full Wave Direct Pwm Motor Driver

Manufacturer: Diodes Incorporated

Overview: Description Green AM9469 LOW NOISE SINGLE PHASE FULL WAVE DIRECT PWM MOTOR DRIVER Pin Assignments The AM9469 is a high performance, ultra-low noise single phase (single-coil) brushless direct.

General Description

Green AM9469 LOW NOISE SINGLE PHASE FULL WAVE DIRECT PWM MOTOR DRIVER Pin Assignments The AM9469 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 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.
