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_in | Boost output intermediate node. Requires two 22uF ceramic decoupling capacitors placed close to the pin. |+| 2 | VOUT | power_out | Boost output pin, connects to the positive terminal of the 2S Li-ion battery pack. Target charge voltage 8.1V-8.4V (set by RVSET), charge current up to 1.2A. |+| 3 | VSET | input | Constant-voltage charge voltage set pin. An external resistor RVSET to GND programs the CV target: NC=8.4V, 120K=8.3V, 68K=8.2V, 1K=8.1V. |+| 4 | NTC | input | NTC temperature protection pin. Sources 20uA into an external NTC thermistor network; voltage thresholds VH=0.43V / VM=0.56V / VL=1.32V determine over/under-temperature actions. Tie via 51K to GND to disable. |+| 5 | LED | output | Charge status LED driver output. Max drive current 5mA. LED is on during charging, off when full, and blinks on fault/abnormal conditions. |+| 6 | VIN | power_in | Input supply and sensing pin. Recommended 4.5-5.5V (typ 5V), abs max 20V. UVLO ~4.5V, OVP ~5.75V. Quiescent input current ~20mA. |+| 7 | BST | passive | Bootstrap capacitor pin for the high-side gate drive. Place a 0.1uF capacitor between BST and LX close to the IC. |+| 8 | LX | power_out | DCDC switching node. Connects to the boost inductor (typ 2.2uH) at 500KHz switching frequency. |+| EPAD | GND | power_in | Exposed thermal pad and system/power ground. Solder to the PCB ground plane for thermal dissipation (θJA ≈ 60°C/W). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | INJOINIC |+| Package | ESOP-8 |+| Category | PMIC |+| Pins | 9 |++## Ordering variants++- `IP2325`+- `IP2325_8V8`+- `IP2325_DA`+- `IP2325_3S`++## CAD (KiCad official)++- Symbol: `IP2325`+- Footprint: `Package_SO:SOIC-8-1EP_3.9x4.9mm_P1.27mm_EP2.41x3.3mm`+- 3D model: ESOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [INJOINIC datasheet](docs/ip2325-datasheet.pdf) (11 pp, sha256 `ebb55c816a3b7cf0`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
