MAX708ESA-HXY

HXY MOSFET · Supervisor And Reset ICs · SOP-8

MAX708ESA-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 internal 20kΩ (10-40kΩ) pull-up; VIH 2.0V min and VIL 0.8V max at 4.5V<VCC<5.5V.
2 VCC power_in Power supply input; operating range 1.1V/1.2V to 5.5V, with reset threshold of 4.40V for the 708.
3 GND power_in Ground.
4 PFI input Inverting input of the internal 1.25V power-fail comparator (threshold 1.25V typ); connect to GND or VCC when unused.
5 !PFO output Output of the internal 1.25V power-fail comparator, sinks 3.2mA at VOL ≤0.4V (4.5V<VCC<5.5V).
6 NC unconnected No connection.
7 !RESET output Active-low reset output, 200ms typical reset pulse width, sinks 3.2mA at VOL ≤0.4V (4.5V<VCC<5.5V).
8 RESET output Active-high reset output, inverse of !RESET, 200ms typical reset pulse width.
