Single-phase Full-wave Motor Driver
Datasheet
SDC11170
General Description
SDC11170 is a single-phase full-wave driver for fan motor.
It features a variable speed control method using both PWM input and thermistor and a high-efficiency driver architecture.
An external filter is introduced to reduce the vibration and acoustic noise.
SDC11170 is ideal for a quiet and high-efficiency cooler fan.
