# MX74610SS

**Wuxi Maxinmicro** · Power Distribution Switches · MSOP-8

MX74610SS from Wuxi Maxinmicro, in a MSOP-8. 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 | VCAPL | power_out | Charge pump output connected to an external charge pump capacitor; the VCAP lower threshold is 5.0V (typical). |
| 2 | GATE PD | output | Connect to the gate of the external MOSFET for fast turn-off in the case of reverse polarity; it pulls the gate down with 160mA pull-down current (typical) when reverse voltage is sensed. |
| 3 | NC | unconnected | No internal connection. |
| 4 | ANODE | passive | ANODE of the diode, connected to the source of the external MOSFET for sensing; reverse threshold across ANODE and CATHODE is -20mV (typical). |
| 5 | NC | unconnected | No internal connection. |
| 6 | GATE | output | Gate drive output connected to the gate of the external MOSFET; it sources 8µA (typical) when VCAP is at its high threshold and is clamped to 11.5V (Zener) VGS. |
| 7 | VCAPH | power_out | Charge pump output connected to an external charge pump capacitor; the VCAP upper threshold is 6.3V (typical). |
| 8 | CATHODE | passive | CATHODE of the diode, connected to the drain of the external MOSFET for sensing; operating range is 0 to 55V continuous. |
