3.Pin function
Pin no. | Symbol | Function |
|
|
|
1 | 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 | Output selector of CD. AUDIO, ILM and EXT. |
9 | VCC | To be connected with the BACK UP of car. |
10 | ILM output | This output voltage is 10V, and max output current is 500mA. |
|
| Output voltage is adjustable. |
11 | AJ | Putting a resistance between ILM and AJ or between AJ and GND |
|
| makes ILM output voltage adjustable. |
12 | GND | Ground. |
