UC2902D

Texas Instruments · Battery Management · SOIC-8

UC2902D from Texas Instruments, in a SOIC-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 GND power_in Local power supply return and signal ground; all voltages in the datasheet are referenced to GND.
2 SENSE input Inverting input of the current sense amplifier, with an absolute maximum input voltage range of −5 V to 5 V.
3 ADJ output Current output of the adjust amplifier circuit (NPN collector), with an absolute maximum voltage of −0.3 V to 20 V and output current of −1 mA to 30 mA.
4 ADJR output Current adjust amplifier range set (NPN emitter), with the ADJR and COMP input voltage limited to −0.3 V to 4 V absolute maximum.
5 COMP bidirectional Output of the error amplifier and input of the adjust amplifier, with an absolute maximum voltage of −0.3 V to 4 V.
6 SHARE− input Reference for the SHARE+ pin, with an absolute maximum voltage of −0.3 V to 10 V.
7 SHARE+ bidirectional Positive input from the share bus or drive-to-share bus, with an absolute maximum voltage of −0.3 V to 10 V and output current limits of −100 mA to 10 mA.
8 VCC power_in Local positive power supply, operating from 2.7 V to 20 V with an absolute maximum range of −0.3 V to 20 V.
