NCS199A1RSQT2G

onsemi · Current Sense Amplifiers · SC-70-6

NCS199A1RSQT2G from onsemi, in a SC-70-6. 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 that sets the output offset, must be driven from a low-impedance source, and must not exceed VS+0.3 V.
2 GND power_in Ground.
3 VS power_in Supply voltage input, 2.2 V to 26 V operating range with 30 V maximum.
4 IN+ input Non-inverting shunt sense input, common-mode range -0.3 V to 26 V.
5 IN- input Inverting shunt sense input, common-mode range -0.3 V to 26 V.
6 OUT output Voltage output equal to ILOAD x RSHUNT x GAIN (50 V/V for NCS199A1R) plus VREF, swinging from GND to within 200 mV of VS.
