Single-phase Full-wave Motor Driver
Datasheet
SDC11169
General Description
The SDC11169 is a single-phase bipolar drive motor driver
that easily implements direct PWM drive systems with
high excellent efficiency. The SDC11169 is optimal for fan
motor driver in personal computer power supply systems
and CPU cooling fan systems.
Applications
CPU cooler fan
