**Wuxi Maxinmicro** · Power Distribution Switches · SOT-23-6L

MX74610T from Wuxi Maxinmicro, in a SOT-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 | CATHODE | input | Cathode of the diode, connected to the drain of the external MOSFET; the pin senses the MOSFET drain voltage against ANODE, with a reverse-voltage fault threshold of -20mV. |
| 2 | GATE PD | output | Connect to the gate of the external MOSFET for fast turn-off in the case of reverse polarity; it can pull down the gate with 160mA pull-down current. |
| 3 | GATE | output | Gate drive output that connects to the gate of the external MOSFET; the gate drive provides 6.8µA typical pull-down current during forward operation and is clamped by an internal 11.5V Zener to limit VGS. |
| 4 | ANODE | input | Anode of the diode, connected to the source of the external MOSFET for sensing; the current into the Anode pin is 30µA typical. |
| 5 | VCAPH | power_out | Charge pump output, connected to an external charge pump capacitor (ceramic X7R/COG, 220nF to 4.7µF, 16V or higher recommended); the upper threshold is 6.3V typical. |
| 6 | VCAPL | power_out | Charge pump output, connected to an external charge pump capacitor; the lower threshold is 5.15V typical. |
