Application Notes
Existing Ship Mode
When a battery is first connected, the IC will enter the ultra-low-current ship mode, which it will exit when voltage is first applied to the SUPPLY pads. Ship mode can be re-entered either programmatically or by disconnecting/reconnecting the battery.
Normally-On Operation
When the SW pad is floating, the LDO output will be connected. Connect SW to GND/SUPPLY- to turn off the output.
Low-Power Mode
In the default low-power mode, the I2C interface is disabled. To exit low-power mode, drive the LP to greater than 1.35V.
Pad Assignments
| Pad | Type | Function | Note | |
|---|---|---|---|---|
| 1 | ⏻ | GND | ||
| 2 | D | LP | drive greater than 1.35V to exit low-power mode when in battery-powered mode (internal 900k pull-down). | |
| 3 | D | SW | connect to GND to disable the LDO output (battery charging will be unaffected). | |
| 4 | I2C | CLK | ||
| 5 | I2C | DAT | ||
| 6 | ⏻ | BATT- | ||
