4-channel PWM driver for CD, MD player

BH6519FS

Description

Dimension (Units : mm)

Features

Applications

The BH6519FS is a 4-channel PWM driver developed

for both motor and actuator driving functions in CD and

MD players. The device requires lower power consumption

due to the adoption of power MOSFET in the output.

00W137A

1) Built-in 4ch power MOSFET H bridge
