IP2325_DA

INJOINIC · Battery Management · ESOP-8

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).
