SINGLE PHASE HALL EFFECT LATCH SMART FAN MOTOR CONTROLLER Description The AH5795 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 (Top View) FG Vss O2 1 2 3 6 5 4 PWM Vdd O1 NEW PRODUCT Motor speed can be controlled by either changing the duty ratio of the PWM signal at the PWM pin or by varying the supply voltage at Vdd pin. To help protect the motor coil, the AH5795 provides Rotor Lock Protection which shuts down the output drive if rotor...
