SA56202 Datasheet PDF

Philips SA56202

The SA56202 is a one-chip motor driver IC that is capable to drive all motors of CD or DVD systems: spindle, sled and loading motors and actuators on the optical pick-up unit. The driver intended for the 3-phase, brushless, Hall-commutated spindle motor uses True-Silent PWM. This proprietary technology ensures that all 3-phase motor currents are sinusoidal resulting in an optimally silent driver.
