MAX706PESA-HXY

HXY MOSFET · Monitors & Reset Circuits · SOP-8

MAX706PESA-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 (10-40kΩ) pull-up; input thresholds are 2.0V/0.8V for 4.5V<VCC<5.5V.
2 VCC power_in Power supply input; the 706P/R operates with VCC of 3.0V to 5.5V and its reset threshold is 2.63V.
3 GND power_in Ground.
4 PFI input Inverting input of the internal 1.25V power-fail comparator (1.25V threshold); connect to GND or VCC when unused.
5 !PFO output Output of the internal 1.25V power-fail comparator.
6 WDI input Watchdog input (1.6s typical timeout); leaving it floating disables the watchdog function.
7 RESET output Active-high reset output (706P), the inverse of !RESET, with a 200ms typical reset pulse width.
8 !WDO output Watchdog output.
