SA56203 Datasheet (NXP) - One-chip motor driver

SA56203, One-chip motor driver

The SA56203 is a one-chip motor driver IC that is capable of driving all motors of CD or DVD systems e.g.

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 PWM switching.

Internal regeneratio

SA56203 Features

* s Low heat generation due to power-efﬁcient direct full-bridge switching of spindle motor driver s Controlled spindle motor current during acceleration and brake s Reverse torque brake function (full bridge) s Adjustable spindle motor current limiter s Internal regeneration for EMF of spindle motor
