MAX813LESA-HXY

HXY MOSFET · Supervisor and Reset ICs · SOP-8

MAX813LESA-HXY from HXY MOSFET, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 !MR input Manual reset input, active low. Internally pulled up to VCC through ~20kΩ (10-40kΩ). A logic low forces the RESET output active for the reset timeout period after !MR returns high.
2 VCC power_in Supply voltage input. Operating range 1.1V to 5.5V (typical monitored range for 813L is 5.0V to 5.5V with 4.65V reset threshold). Typical ICC ≈ 75µA.
3 GND power_in Ground reference (0V) for all supply and signal pins.
4 PFI input Power-fail comparator inverting input. Compared against internal 1.25V reference (threshold 1.20V-1.30V). Drive !PFO low when PFI < 1.25V. Tie to GND or VCC when unused. Input current ±25nA typical.
5 !PFO output Power-fail comparator output, active low. Goes low when PFI drops below the 1.25V reference. Push-pull output (VOH = VCC-1.5V @ 800µA, VOL = 0.4V @ 3.2mA).
6 WDI input Watchdog input. Must be toggled within the watchdog timeout (1.6s typ, 1.0-2.25s) or !WDO asserts low. Leaving WDI floating disables the watchdog function.
7 RESET output Active-high reset output for the 813L variant (inverse polarity of !RESET). Asserts high when VCC falls below 4.65V threshold, during !MR low, and for 200ms after VCC recovers. Push-pull output (VOH = VCC-1.5V @ 800µA, VOL = 0.4V @ 3.2mA).
8 !WDO output Watchdog output, active low. Asserts low if WDI is not toggled within the watchdog period or during reset. Push-pull output (VOH = VCC-1.5V @ 800µA, VOL = 0.4V @ 1.2mA).
