TPA191A2-SC6R

3PEAK · Global Sourcing Parts · SOT-363

TPA191A2-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: connect to GND for unidirectional sensing or to a low-source-impedance reference (typically VS/2) for bidirectional sensing, with a reference input range of 0 V to VS for VS = 2.7 V to 5.5 V and 0 V to 5.5 V for VS = 5.5 V to 36 V.
2 GND power_in Ground reference pin for the device.
3 VS power_in Power supply input, operating from 2.7 V to 36 V (absolute maximum supply voltage 42 V).
4 IN+ input Non-inverting sense input, with a common-mode input voltage range of −0.3 V to 36 V independent of VS.
5 IN- input Inverting sense input, which together with IN+ forms the differential shunt voltage VSENSE = VIN+ − VIN− that is amplified.
6 OUT output Amplifier output, referenced to GND when REF is grounded or to VREF in bidirectional mode, swinging within GND − 0.3 V to VS + 0.3 V per the absolute maximum ratings.
