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. |
