Wuxi Maxinmicro · Surge Protection Devices (SPDs) · DFN-10(3x3)

MX6875D33 from Wuxi Maxinmicro, in a DFN-10(3x3). 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 VIN power_in Input supply voltage, operating range 3.3V to 14.4V
2 VIN power_in Input supply voltage, operating range 3.3V to 14.4V
3 VIN power_in Input supply voltage, operating range 3.3V to 14.4V
4 VCP input Overvoltage clamp threshold selection; pull high for 5.9V clamping or low/float for 13.6V clamping threshold
5 ILMT input Resistor to ground sets overload and short circuit current limit, programmable from 0.4A to 5.2A
6 dVdT input Capacitor to ground controls output voltage ramp rate at device turn-on, typical 1ms to 10ms for 0-12V
7 EN input Enable input; high state (>1.4V) enables internal MOSFET, low state (<1.35V) disables device
8 OUT tri_state Output pin; supplies load current with programmable limit up to 5A and integrated overvoltage protection
9 OUT tri_state Output pin; supplies load current with programmable limit up to 5A and integrated overvoltage protection
10 OUT tri_state Output pin; supplies load current with programmable limit up to 5A and integrated overvoltage protection
11 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
