MPQ8113AGJ-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; for the MPQ8113A connect an external resistor between OUT and ground to set the gain, while the MPQ8113 has an internal 10kΩ resistor to ground and OUT can be left floating. |
| 2 | RG2 | input | Negative gain resistor pin; for the MPQ8113A connect to the load side of the sense resistor through gain resistor RG2, which should be below 4kΩ (1kΩ recommended). |
| 3 | RG1 | input | Positive gain resistor pin that must not exceed the VCC voltage; for the MPQ8113A connect to the power side of the sense resistor through gain resistor RG1, which should be below 4kΩ (1kΩ recommended). |
| 4 | VCC | power_in | Power input supplying the internal input stage amplifier (2.7V to 60V); place a 0.1µF to 1µF low-ESR ceramic bypass capacitor to GND close to the pin. |
| 5 | GND | power_in | Ground. |
| 6 | V5 | power_in | Supply for internal control and output block (2.7V to 5.5V, source must supply above 5mA) that enables the part above 2V, disables it below 1.9V, and limits the maximum output voltage; use a 10nF to 100nF bypass capacitor to GND. |
