MIC6315-26D2UY-TR

Microchip Tech · Supervisor And Reset ICs · SOT-143-4

MIC6315-26D2UY-TR from Microchip Tech, in a SOT-143-4. 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 IC ground reference pin.
2 /RESET output Active-low open-drain reset output that goes low when VCC falls below the reset threshold and stays asserted for one reset timeout period after VCC exceeds the threshold; it requires an external pull-up, and the pull-up voltage must be limited to 6.0V or less (absolute maximum).
3 /MR input Manual reset input where a logic LOW forces a reset that remains asserted while held low and for one reset timeout period after it goes HIGH; it can be driven by a switch to ground or by TTL/CMOS logic, and should be left floating if unused.
4 VCC power_in Power supply input with an operating voltage range of 1V to 5.5V.
