MPQ8112GJ-AEC1-Z

Monolithic Power Systems · Current-Sensing Amplifiers · TSOT-23-6L

MPQ8112GJ-AEC1-Z from Monolithic Power Systems, in a TSOT-23-6L. 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 Output pin: OUT to GND is limited to 0V to 20V for the MPQ8112 (which can be left floating) and to 0V to VCC - 0.7V for the MPQ8112A.
2 RG2 input Negative gain resistor connection, kept below 4kΩ for high current-sense accuracy with 1kΩ recommended, and RG1/RG2 to GND rated 0V to VCC.
3 RG1 input Positive gain resistor connection, kept below 4kΩ for high current-sense accuracy with 1kΩ recommended, and RG1 to GND rated 0V to VCC.
4 VCC power_in Power input with a 2.7V to 60V operating supply range, requiring a 0.1µF to 1µF low-ESR ceramic bypass capacitor placed as close as possible between VCC and GND.
5 GND power_in Ground reference for the device, with the VCC bypass capacitor and V5 bypass capacitor returned to this pin.
6 V5 power_in Supply for the internal trim and control block: pull above the 2V upper threshold to enable the part and below the 1.9V lower threshold to disable it, with a source able to supply above 1mA.
