MIC706SMY

Microchip Tech · Monitors & Reset Circuits · SOIC-8

MIC706SMY 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 /MR input Manual reset input forces reset outputs to assert when pulled below 0.8V, with an internal 250µA pull-up that holds it high when floating and TTL/CMOS drivable.
2 VCC power_in Primary supply input, operating up to 5.5V (3.00V to 5.5V for MIC706S) with absolute maximum of 6.0V.
3 GND power_in IC ground pin, 0V reference.
4 PFI input Power-fail comparator input referenced to 1.25V, which should be connected to GND or VOUT if the comparator is not used.
5 /PFO output Power-fail output, independent of all other functions, that remains high while PFI is above 1.25V.
6 WDI input Watchdog input that forces /WDO low if held high or low longer than the 1.6s timeout period, and the watchdog is disabled by floating the pin.
7 /RESET output Active-low reset output asserted when VCC drops below the 2.93V threshold or /MR goes low, and held for 200ms after VCC recovers or /MR goes high.
8 /WDO output Watchdog timer output forced low when WDI is stuck longer than the timeout period or VCC is below the reset threshold, remaining low until VCC returns to a valid level.
