MAX706ESA-HXY

HXY MOSFET · Supervisor And Reset ICs · SOP-8

MAX706ESA-HXY from HXY MOSFET, in a SOP-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 with an internal 20kΩ typical pull-up; pulling it low forces a reset.
2 VCC power_in Power supply input, with a 4.40V reset threshold on the 706 and a 4.8V to 5.5V supply range for the specified electrical characteristics.
3 GND power_in Ground.
4 PFI input Inverting input of the internal 1.25V comparator (threshold 1.25V typical); connect to GND or VCC when unused.
5 !PFO output Output of the internal 1.25V comparator.
6 WDI input Watchdog input; leaving it floating disables the watchdog function (watchdog timeout 1.6s typical).
7 !RESET output Active-low reset output, with a 200ms typical reset pulse width.
8 !WDO output Watchdog output.
