TS391AILT from STMicroelectronics, in a SOT-23-5. 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 | VCC+ | power_in | Positive power supply input, 2 to 36 V single supply or ±1 to ±18 V dual supply. |
| 2 | IN- | input | Inverting comparator input, input common-mode voltage range 0 to (VCC+) - 1.5 V at 25°C. |
| 3 | OUT | output | Comparator output with open-drain characteristic, 250 mV typical saturation voltage at 4 mA sink current. |
| 4 | VCC- | power_in | Negative power supply or ground return, part of ±18 V or single supply configuration. |
| 5 | IN+ | input | Non-inverting comparator input, input common-mode voltage range 0 to (VCC+) - 1.5 V at 25°C. |
