MPQ8112AGJ-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 | Current-mirror output; for the MPQ8112A connect an external resistor ROUT to OUT to set the gain (OUT to GND up to VCC, recommended 0V to VCC - 0.7V). |
| 2 | RG2 | input | Negative gain resistor input; for the MPQ8112A connect to the load side of the current-sense resistor through gain resistor RG2, which should be below 4kΩ (1kΩ recommended) for high current-sense accuracy. |
| 3 | RG1 | input | Positive gain resistor input; for the MPQ8112A connect to the power side of the current-sense resistor through gain resistor RG1, which should be below 4kΩ (1kΩ recommended) for high current-sense accuracy. |
| 4 | VCC | power_in | Power input, 2.7V to 60V; place a 0.1µF to 1µF low-ESR ceramic bypass capacitor between VCC and GND as close as possible. |
| 5 | GND | power_in | Ground. |
| 6 | V5 | power_in | Supply for internal trim and control block (2.7V to 5.5V); above 2V upper threshold enables the part, below 1.9V lower threshold disables it, source must supply above 1mA, with 10nF to 100nF bypass capacitor to GND. |
