6-channel BTL driver for CD players

BA5936S

The BA5936S is a 6-channel BTL driver developed for use as the sled motor, spindle motor , actuator, and loading motor
driver for CD players. It contains a current limiting function and 5V regulator for compatibility in a wide range of applica­tions.

CD players

Features

1) 6-channel BTL driver for CD players.
Contains 4 channels for the focus coil, tracking coil,
sled motor, and spindle motor drives; and 2 channels
for the loading motor driver.

2) Internal 5V regulator with a earth protection circuit
(requires an external PNP transistor).

3) Internal mute circuit (enables the muting of the driver
outputs from all but the loading driver, and muting of
the regulator output).

4) Internal thermal shutdown circuit.
