UC2902N from Texas Instruments, in a PDIP-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 are referenced to GND. |
| 2 | SENSE | input | Inverting input of the current sense amplifier, rated -5 V to 5 V absolute input voltage range. |
| 3 | ADJ | output | Current output of the adjust amplifier circuit (NPN collector), absolute output current -1 mA to 30 mA. |
| 4 | ADJR | output | Adjust amplifier range set (NPN emitter), absolute input voltage -0.3 V to 4 V; a resistor to GND sets the adjust current (about 360 Ω gives about 5 mA in the typical application). |
| 5 | COMP | bidirectional | Output of the error amplifier and input of the adjust amplifier, absolute input voltage -0.3 V to 4 V. |
| 6 | SHARE− | input | Reference for the SHARE+ pin and the system ground connection of the share bus, absolute voltage -0.3 V to 10 V. |
| 7 | SHARE+ | bidirectional | Positive input from the share bus or drive-to-share bus, absolute voltage -0.3 V to 10 V and output current -100 mA to 10 mA. |
| 8 | VCC | power_in | Local power supply (positive), operating range 2.7 V to 20 V with absolute maximum -0.3 V to 20 V. |
