LMP8481AHQDGKRQ1 from Texas Instruments, in a VSSOP-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 | RSP | input | Positive current-sense input, with common-mode voltage range of 4.0 V to 76 V and an absolute maximum of -0.3 V to 85 V to GND. |
| 2 | VCC | power_in | Positive supply voltage, recommended 4.5 V to 76 V, with an absolute maximum of 85 V to GND. |
| 3 | NC | unconnected | No connection; not internally connected on the LMP8481-Q1. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | VOUT | output | Buffered output, with an absolute maximum of -0.3 V to the lesser of (VCC + 0.3) V or +20 V to GND and a current limit of -20 mA to 20 mA into the output pin. |
| 6 | REFB | input | Reference voltage B input; with VREFA and VREFB tied together the recommended range is -0.3 V to the lesser of (VCC - 1.5) V or +6 V, and with the other VREF pin grounded a single pin may go to +12 V. |
| 7 | REFA | input | Reference voltage A input; with VREFA and VREFB tied together the recommended range is -0.3 V to the lesser of (VCC - 1.5) V or +6 V, and with the other VREF pin grounded a single pin may go to +12 V. |
| 8 | RSN | input | Negative current-sense input, with an absolute maximum of -0.3 V to 85 V to GND. |
