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. |
