SGM8198XN5G

SGMICRO · Current Sense Amplifiers · SOT-23-5

SGM8198XN5G from SGMICRO, 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 Current output proportional to the sense voltage (transconductance 1000 µA/V), converted to voltage through a load resistor; output swing up to VCC - 1.6V and absolute maximum -0.3V to 40V.
2 GND power_in Ground reference for the device.
3 VIN+ power_in Positive shunt sense input with common mode range 2.7V to 36V (absolute maximum -0.3V to 40V).
4 VIN- power_in Negative shunt sense input with common mode range 2.7V to 36V (absolute maximum -0.3V to 40V).
5 VCC power_in Supply voltage input, operating range 2.7V to 36V (absolute maximum -0.3V to 40V), 65µA typical quiescent current.
