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). |
