# MIC5013YM

**Microchip Tech** · Pre-ordered Chips · SOIC-8

MIC5013YM from Microchip Tech, in a SOIC-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 | Input | input | Resets the current sense latch and turns on the power MOSFET when taken above the 3.5V typical threshold; requires <1µA to switch. |
| 2 | Threshold | passive | Sets the current sense trip voltage via RTH to ground (3.3kΩ to 20kΩ); adding CTH raises the trip voltage at turn-on to 2V (10µF gives a 10ms time constant). |
| 3 | Sense | input | Current sense trips when VSENSE is VTRIP above VSOURCE; used with a shunt in the source of a 3-lead FET or a resistor RS in the sense lead of a current-sensing FET, and can safely swing to -10V. |
| 4 | Source | passive | Reference for the current sense voltage on pin 3 and return for the gate clamp zener; connects to the load side of the shunt or the Kelvin lead of a current-sensing FET, and can safely swing to -10V (max 50mA into pin). |
| 5 | Gnd | power_in | Ground. |
| 6 | Gate | output | Drives and clamps the gate of the power FET (absolute max -1V to 50V); clamped to approximately -0.7V by an internal diode when turning off inductive loads. |
| 7 | V+ | power_in | Supply pin, 7V to 32V for high side and 7V to 15V for low side (absolute max 36V); decouple with 10µF close to pins 7 and 5. |
| 8 | Fault | output | Outputs protection circuit status when pin 1 is high: low indicates normal operation, high indicates current sense tripped (absolute max ±1mA). |
