UC2902DTR 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. |
| 2 | SENSE | input | Inverting input to the current sense amplifier, −5 to 5 V absolute maximum input voltage range. |
| 3 | ADJ | output | Adjust amplifier NPN collector output, −0.3 to 20 V voltage range with −1 to 30 mA output current capability. |
| 4 | ADJR | output | Adjust amplifier NPN emitter output for current range setting, −0.3 to 4 V operating voltage range. |
| 5 | COMP | bidirectional | Error amplifier output and adjust amplifier input, −0.3 to 4 V operating voltage range. |
| 6 | SHARE− | input | Negative reference input for the differential share bus, −0.3 to 10 V operating voltage range. |
| 7 | SHARE+ | bidirectional | Positive share bus input/output for load-current balancing, −0.3 to 10 V voltage range and −100 to 10 mA output current capability. |
| 8 | VCC | power_in | Positive power supply input, 2.7 to 20 V operating range with 2.3 V minimum startup threshold. |
