6-channel Driver with 3.3V Regulator

BA5801FS

Description

Dimension (Units:mm)

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

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
