IP2364 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 | VSYS | power_out | System voltage pin that requires a 22uF ceramic capacitor placed close to the IC pin and the EPAD; electrolytic capacitors are not allowed. |
| 2 | VIN | power_in | Input voltage pin with recommended operating range 14V to 24V (typical 20V) and absolute maximum range -0.3V to 28V. |
| 3 | VINSEN | input | Input voltage sense pin that sets the input undervoltage threshold via an external divider, reduces charge current when it falls to 1.5V, stops charging and enters standby below 1.3V, and can be used as an enable pin. |
| 4 | LED | output | Charge status indicator output that drives an LED with a stated output current of 5mA to 10mA. |
| 5 | NTC | input | NTC temperature protection pin that sources 20uA into an external NTC resistor to GND; if NTC is unused it must be tied to GND through 51kΩ and must not be left floating. |
| 6 | FB | input | Output voltage feedback pin whose constant-voltage target is 2.1V typical (2.05V to 2.15V), and external divider resistors RFB1/RFB2 should be 0.1% precision. |
| 7 | BST | passive | Bootstrap pin that requires a bootstrap capacitor placed close to the BST and LX pins to provide gate-drive voltage for the high-side switch, with VBST limited to VLX + 7V. |
| 8 | LX | output | DC-DC switching node that connects to the inductor, with voltage range -0.3V to VIN + 0.3V. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
