Overview
Optical disc ICs 3-channel BTL driver for CD players BA5933FP-Y The BA5933FP-Y is a 3-channel BTL driver for CD player actuators and motors.
This IC has an internal 5V regulator and a standard operational amplifier, and comes in a HSOP 25-pin package, allowing for application miniaturization.
FApplications CD players and CD-ROM drives FFeatures 1) 3-channel BTL driver.
2) HSOP 25-pin power package allows for application miniaturization.
3) Internal standby function.
4) Internal thermal shutdown circuit.
FAbsolute maximum ratings (Ta = 25_C) 5) Gain is adjustable with an attached resistor.
6) Internal 5V regulator.
(requires attached PNP transistor) 7) Internal standard operational amplifier.

The output current is muted when the chip temperature rises above 175_C (typically).
When the chip temperature falls to 150_C (typically), the driver circuit starts up again.
(2) The output current can be muted by opening the mute pin (pin 6) voltage or lowering it below 0.
5V.
During normal use, pin 6 should be pulled up above 2.
0V.
(3) The bias pin (pin10) is muted when lowered below 1.
4V (typically).
Make sure it stays above 1.
6V during normal use.
(4) Muting occurs during thermal shutdown, mute-on operations or a drop in the bias pin voltage.
In each case, only the drivers are muted.
During muting, the output pins FElectrical characteristic curves BA5933FP-Y remain at the internal bias voltage, roughly (VCC / 2).
