PUOLOP · Battery Management · SOT-23-6L

PT8261 from PUOLOP, in a SOT-23-6L. 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 OD output Discharge-control MOSFET gate drive output. Drives the gate of the external N-MOSFET (M1) that gates discharge current; output is VDD-0.02 V (typ) when high and 0.1 V (typ) when low.
2 CS input Overcurrent-detection input and charger-detection input. Monitors the voltage between CS and VSS to detect discharge overcurrent (VDIP=80 mV typ), load short-circuit (VSIP=0.58 V typ) and charge overcurrent (VCIP=-100 mV typ). Absolute-max range VDD-25 V to VDD+0.3 V.
3 OC output Charge-control MOSFET gate drive output. Drives the gate of the external N-MOSFET (M2) that gates charge current; high-voltage-tolerant terminal (absolute max VDD-25 V to VDD+0.3 V) for use with high-voltage chargers.
4 NC unconnected No connection. Leave floating on the PCB.
5 VDD power_in Positive supply input. Connect to the battery + terminal through R1 (typ 100 Ω) with a 0.1 µF bypass to VSS. Operating range 1.5 V to 8 V (VDD-VSS); absolute max VSS-0.3 V to VSS+10 V. IDD = 3.0 µA typ (6.0 µA max) at VDD=3.9 V.
6 VSS power_in Negative supply / ground reference input. Connect to the battery - terminal; serves as the 0 V reference for all internal detection circuits.
