MX5052S

Wuxi Maxinmicro · Power Distribution Switches · SOP-8

MX5052S from Wuxi Maxinmicro, in a SOP-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 VS power_in Main supply pin for all internal biasing and auxiliary supply for the gate drive charge pump, operating at 5V to 40V and typically connected to VOUT or VIN (a separate supply may be used).
2 GND power_in Ground return for the controller.
3 IN input Voltage sense connection to the external MOSFET source pin, with a recommended range of 1V to 40V (VS≥4.5V required when IN is below 4V) and an absolute maximum of -0.3V to 50V.
4 IN input Voltage sense connection to the external MOSFET source pin, with a recommended range of 1V to 40V (VS≥4.5V required when IN is below 4V) and an absolute maximum of -0.3V to 50V.
5 OUT input Voltage sense connection to the external MOSFET drain pin, with a recommended range of 1V to 40V (VS≥4.5V required when IN is below 4V) and an absolute maximum of -0.3V to 50V.
6 OUT input Voltage sense connection to the external MOSFET drain pin, with a recommended range of 1V to 40V (VS≥4.5V required when IN is below 4V) and an absolute maximum of -0.3V to 50V.
7 OUT input Voltage sense connection to the external MOSFET drain pin, with a recommended range of 1V to 40V (VS≥4.5V required when IN is below 4V) and an absolute maximum of -0.3V to 50V.
8 OUT input Voltage sense connection to the external MOSFET drain pin, with a recommended range of 1V to 40V (VS≥4.5V required when IN is below 4V) and an absolute maximum of -0.3V to 50V.
