IP2325_DA 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 | VSYS | power_out | Boost converter intermediate output node; place two 22μF ceramic capacitors in close proximity to the pin. |
| 2 | VOUT | power_out | Boost converter output connected to battery positive terminal; target voltage adjustable from 8.1V to 8.4V via external resistor RVSET. |
| 3 | VSET | input | Constant voltage charging voltage setting pin; external resistor RVSET selects target voltage from 8.1V (1K) to 8.4V (open circuit). |
| 4 | NTC | input | NTC temperature protection pin outputting 20μA constant current; voltage 0.43V-0.56V reduces charge current by half, below 0.43V stops charging, above 1.32V stops charging, normal operation 0.56V-1.32V. |
| 5 | LED | output | LED indicator output with maximum 5mA drive current; indicates charging status with flashing during charge and constant on when fully charged for IP2325_DA variant. |
| 6 | VIN | power_in | Input power supply and detection pin; operates from 4.5V to 5.5V nominal with integrated input regulation loop maintaining voltage near 4.5V minimum threshold. |
| 7 | BST | power_out | Bootstrap circuit supply pin for gate driver; place 0.1μF capacitor between BST and LX pins in close proximity to power high-side MOSFET switch. |
| 8 | LX | output | DCDC switch node connected to 2.2μH external inductor; operates at 500kHz switching frequency with integrated synchronous power MOSFET switches. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
