Product Summary

The SA5888 is a five-channel BTL driver IC for driving the motors and actuators in products such as CD - ROM / DVD drivers. It is also build-in two independent precision voltage regulators with adjustable range from 1.5V to 4V and one channel bi-direction DC motor driver for tray. The applicaitons of the SA5888 include CD, CD-ROM and DVD.

Parametrics

SA5888 absolute maximum ratings: (1)Power Supply Voltage, VCC, 1/2PVCC: 8 V; (2)Power Dissipation, PD: 1.7W; (3)Operating Temperature, Topr: -35~+85℃; (4)Storage Temperature, Tstg: -55~+150℃.

Features

SA5888 features: (1)Wide dynamic range (4.0V (Typ.) when VCC = 8V, PVCC =5V, and RL = 8Ω); (2)Level shift circuit on chip; (3)Thermal shutdown circuit on chip; (4)Mute mode built-in; (5)Two regulator controllers built-in; (6)Five drivers build-in: dual actuator drivers, sled motor driver, spindle driver and tray in-out drive.
