TSC1031IYDT from STMicroelectronics, in a SOIC-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 | Vm | input | Analog input for the external sense resistor, where the measured current exits the shunt on the Vm side; absolute maximum -16 to 75 V relative to Vcc-. |
| 2 | A1 | output | Analog output used for the connection to the output resistor (Rf3 between A1 and Gnd balances the input filter resistors); limited to -0.3 V to Vcc+ + 0.3 V relative to Gnd. |
| 3 | SEL | input | Digital gain-select input that sets K2 to 2.5 (SEL = Gnd, gain 50 V/V) or 5 (SEL = Vcc+, gain 100 V/V), with VIL max 0.5 V and VIH min 1.2 V. |
| 4 | Out | output | Analog output voltage proportional to the sense voltage Vp-Vm, with a total gain of 50 V/V or 100 V/V and a short-circuit current of 15 to 26 mA. |
| 5 | Vcc+ | power_in | Positive power supply line, 2.7 to 5.5 V in single-supply configuration and absolute maximum 7 V relative to Gnd. |
| 6 | Gnd | power_in | Ground line, which is the reference for the Vcc+, SEL, A1 and Out pin voltages. |
| 7 | Vcc- | power_in | Negative power supply line, connected to Gnd in single-supply configuration or to a negative supply of -8 to 0 V (Vcc+ = 5.5 V max) in dual-supply configuration, with Vcc+ - Vcc- limited to 15 V. |
| 8 | Vp | input | Analog input for the external sense resistor, where the measured current enters the shunt on the Vp side; absolute maximum -16 to 75 V relative to Vcc-. |
