TPA191A4-SC6R

3PEAK · Current Sense Amplifiers · SOT-363

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.
