Troubleshooting and error codes
| Pin No. | 1/0 | Active Level | Abbreviation | Function |
|---|---|---|---|---|
| 1 | I | Hi | RESET | Resets this UP. |
| 2 | I | NC | Not used. (External interrupt input.) | |
| 3 | GND | Ground terminal of the analog power input (for A/D converter). | ||
| 4 | I | Hi | V.REF | Reference power input for the A/D converter. This pin is connected to the 5V line together with pin 3. |
| 5 | I | Hi | A/D V IN | Analog input of the A/D converter. Receives the output voltage level. |
| 6 | I | Hi | A/D I IN | Analog input of the A/D converter. Used as an input to detect the output current. |
| 7 | Vcc | Positive terminal of the analog power input (for the A/D converter). | ||
| 8 | I | Hi | BATT. IN | Receives the stage of the battery attachment/detachment detection switch. Hi: attachment, Lo: detachment |
| 9 | I | Hi | CHARGE MONI. | Detects whether there is a voltage at the charge output terminal or not. |
| 10 | I | Hi | CHARGE LEVEL DET | Detects whether the specified voltage appears at the charge output terminal or not. Detects the level of 1.5V and 15V depending on the level at pin 16. |
| 11 | I | Hi/Lo | 1Hr/2Hr | Detects the state of the battery 1Hr/2Hr detection switch. Hi: 1 hour battery, Lo: 2 hours battery |
| 12 | O | Hi/Lo | CHARGE ON/OFF | Turns on/off the trickle charge output. H1: ON, Lo: OFF |
| 13 | O | Lo | CURRENT SUPPRESS | Goes "Lo" when there is an output voltage in the abnormal mode and reduces the output current. |
| 14 | GND | Ground terminals of power input of the UP. | ||
| 15 | GND | |||
| 16 | O | Hi/Lo | BATT. MOUNT | Goes "Hi" as soon as a battery is attached. Hi: 15V, Lo: 1.5V |
| 17 | O | Hi/Lo | CHARGE/ADP | Switches between the adapter mode and charge mode. Hi: charge, Lo: Adapter |
