TSC888CILT

STMicroelectronics · Current Sense Amplifiers · SOT-23-5

TSC888CILT from STMicroelectronics, in a SOT-23-5. 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 Out output The buffered, ground-referenced output voltage is proportional to the sense voltage Vp-Vm, with DC output pin voltage limited to -0.3 V to Vcc.
2 Gnd power_in Ground line; all voltages in the absolute maximum ratings are measured with respect to this pin.
3 Vp input Connection for the external sense resistor on the side where the measured current enters the shunt; the input voltage range is -0.3 V to 30 V relative to Gnd and the differential Vp-Vm is limited to ±2 V.
4 Vm input Connection for the external sense resistor on the side where the measured current exits the shunt; the input voltage range is -0.3 V to 30 V relative to Gnd and the common-mode range is 2.8 V to 24 V.
5 Vcc power_in Positive power supply line, operating from 4.0 V to 24 V and independent of the input common-mode voltage; DC supply absolute maximum is -0.3 V to 25 V.
