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. |
