YD5954 - Actuator Driver

Datasheet Summary

Description

The YD5954 is a four-channel BTL driver IC for driving the motors and actuators in products such as CD-ROM/DVD drivers.

Two of the channels use current feedback to minimize the current phase shift caused by the influence of load inductance.

Features

Wide dynamic range(4.0V(typ. ) when Vcc=12V, PVCC=5V, and RL=8¦¸.
Level shift circuit on chip.
Thermal shutdown circuit on chip. ). BLOCK.
