INJOINIC · Battery Management · ESOP-8
IP5306-LC from INJOINIC, in a ESOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | DC5V charging input pin; recommended input range is 4.75 V to 5.5 V (typical 5 V), with an absolute maximum of -0.3 V to 5.5 V. |
| 2 | LED1 | output | LED drive pin for the battery-level indicator, driving segment D1. |
| 3 | LED2 | output | LED drive pin for the battery-level indicator, driving segment D2. |
| 4 | LED3 | output | LED drive pin for the battery-level indicator, driving segment D3. |
| 5 | KEY | input | Button input that is multiplexed with the light drive; leave it floating when no button is used, a press of 30 ms to 2 s turns on the level display and boost output, and a press longer than 2 s toggles the light LED. |
| 6 | BAT | power_in | Boost input pin connected to the positive terminal of the lithium battery, with a stated battery operating voltage of 3.0 V to 4.4 V. |
| 7 | SW | passive | DC-DC switching pin that connects to the single boost/charge inductor. |
| 8 | VOUT | power_out | 5 V boost output pin, giving 5.0 V DC output at VBAT=3.7 V with a stated output current capability of 2.4 A. |
| 9 | PowerPAD | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
