MCP1402T-E

Microchip Tech · Gate Drivers · SOT-23-5

MCP1402T-E from Microchip Tech, in a SOT-23-5. 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 GND power_in Ground return pin that must have a low-impedance connection to the bias supply return, and which carries high peak currents when the capacitive load discharges.
2 VDD power_in Bias supply input rated 4.5 V to 18 V that must be decoupled to ground with a local capacitor to supply the peak driver current.
3 IN input High-impedance TTL/CMOS-compatible control input with hysteresis; the input range is -5 V to VDD + 0.3 V, and on the MCP1402 the output is non-inverting with respect to this input.
4 GND power_in Second ground pin, which the datasheet states must be connected together with pin 1 for the device to operate correctly.
5 OUT output CMOS push-pull output that withstands 0.5 A peak sink/source current at VDD = 18 V and 0.5 A latch-up reverse current.
