TPA191A4-SC6R from 3PEAK, in a SOT-363. 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 | REF | input | Reference voltage input, specified from 0 V to VS; connecting it to GND selects unidirectional sensing. |
| 2 | GND | power_in | Ground pin for the device. |
| 3 | VS | power_in | Power supply input, specified from 2.7 V to 36 V. |
| 4 | IN+ | input | Noninverting input of the current-sense amplifier, sensing the drop across the shunt with IN−. |
| 5 | IN- | input | Inverting input of the current-sense amplifier, where VSENSE = VIN+ − VIN−. |
| 6 | OUT | output | Amplifier output, rated in absolute maximum ratings from GND − 0.3 V to VS + 0.3 V. |
