IP5305T from INJOINIC, in a ESOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | 5V input charging pin with recommended operation range 4.65-5.5V and overvoltage threshold at 5.5-5.7V. |
| 2 | LED1 | output | LED display driver pin 1 outputting 2-15mA; selects battery type via pull-down resistor RVSET (43K for 4.3V, 75K for 4.35V, 100K for 4.4V, or floating for 4.2V). |
| 3 | LED2 | output | LED display driver pin 2 outputting 2-15mA; selects charge display threshold via pull-down resistor RVTHS with five configuration levels (20K, 43K, 75K, 100K, or floating). |
| 4 | LED3 | output | LED display driver pin 3 outputting 2-15mA for 3-4 LED display modes. |
| 5 | KEY | input | Key/button input with debounce time 30-100ms; short press (>30ms, <2s) enables display and boost output; long press (>2s) toggles illumination LED; leave floating when not used. |
| 6 | BAT | power_in | Lithium battery positive terminal accepting 3.0-4.4V nominal voltage with low voltage protection threshold at 2.85-3.05V. |
| 7 | SW | output | DC-DC converter switching node connected to external inductor; operates at 250-450KHz (discharge mode) or 600-800KHz (charge mode) with PMOS on-resistance 70-90mΩ and NMOS on-resistance 60-80mΩ. |
| 8 | VOUT | power_out | 5V boosted output pin providing 1.0A maximum output current with regulation voltage 4.75-5.25V and output ripple 20-100mV. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
