RESET

If VDD voltage becomes 4V or less.RESET output becomes low level.

2

EXT output

This output voltage is approximately 0.5V lower than VCC. and max output current is 300mA.

3

COMP output

A voltage supply for ACC block. This output voltage is approximately 0.7V lower than VDD'S. The max output current is 100mA.

4

ACC

Control of the COMP output by inputting voltage.

5

VDD output

This output voltage is 5.7V, and max output current is 100mA.

This voltage supply is for microcomputer. Whenever back up voltage supply is connected, the output keeps on running.

6

AUDIO output

This output voltage is 9.0v, and max output current is 500mA.

This voltage supply for AUDIO.

7

CD output

This output voltage is 8.0V, and max output current is 1A.

This voltage supply for CD.

8

CTRL
