6-channel Driver with 3.3V Regulator
BA5801FS
Description
The BA5801FS is a 6-channel BTL driver for the
actuator and motor driver of a CD player. Three
channels include internal filters which allow for direct
coupling of the digital servo LSI PWM output, without
the need for any external components. Since power
supply terminals of 2-channel Loading driver are
separated, It can be operated by only Loading driver.

1) 6-channel BTL driver (2-channels Loading Driver.)
includes 3.3V regulator (PNP-Tr is needed outside.)
2) Three channels include internal filters which allow for
SSOP-A54
direct coupling of PWM output.
3) Filter constant can be variable by external RC.
4) 1-channel includes operational amplifier (input)
5) Loading driver can be operated by only LDVcc(Pin.51,Isolated power supply)
since its structure is different from other blocks.
6) Loading driver output can be set up by voltage establishment terminal.
7) By separating Vcc into Pre and Power makes for improved power efficiency.
8) Driver mute function(4-channels except loading and regulator mute)
9) Thermal protection circuit built-in
