MIC2779L-2YM5-TR

Microchip Tech · Monitors & Reset Circuits · SOT-23-5

MIC2779L-2YM5-TR 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 HTH input High-Voltage Threshold analog comparator input; when the level initially rises above VREF (1.240V typ), the delay generator cycles and /RST remains low for a minimum of 140 ms.
2 GND power_in Ground.
3 LTH input Low-Voltage Threshold analog comparator input; when the level falls below VREF, /RST is asserted and latched until VHTH > VREF.
4 /RST output Active-low push-pull reset output that is asserted and latched when VLTH < VREF and remains latched until VHTH > VREF.
5 VDD power_in Independent power supply input for internal circuitry, operating range 1.5V to 5.5V.
