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. |
