MX26631S

Wuxi Maxinmicro · Surge Protection Devices (SPDs) · SOP-8

MX26631S from Wuxi Maxinmicro, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN power_in Power input from 4.5V to 40V recommended operating range or -0.3V to 60V absolute maximum.
2 IN power_in Power input from 4.5V to 40V recommended operating range or -0.3V to 60V absolute maximum.
3 GND power_in System ground pin.
4 UVLO input Undervoltage lockout threshold input; connect to GND for 15V default threshold or use resistor divider for 1.18V to 1.28V (rising) adjustable threshold.
5 SHDN input Shutdown control input; below 0.8V (typical) enters shutdown mode, above 1.44V resumes operation and resets fast-latched faults.
6 ILIM input Current limit setting resistor connection; connect 5kΩ to 100kΩ resistor to GND to set overload and short circuit current limit from 0.6A to 3A.
7 OUT power_out Power output supporting up to 3A continuous current with 20mΩ to 50mΩ ON resistance.
8 OUT power_out Power output supporting up to 3A continuous current with 20mΩ to 50mΩ ON resistance.
