The MAX708SESA-TG is a MicroPower Supervisor Circuit designed to monitor VCC in digital systems and provide a reset signal to the host processor when necessary. No external components are required. The reset output is driven active within 20 seconds of VCC falling through the reset voltage threshold. Reset is maintained with 200ms of delay time after VCC rise above the reset threshold. It has a low quiescent current of 12μA at VCC=3.3V, an active-high RESET and active-low RESET with a push-pull output. The output is guaranteed valid down to VCC=1V. It has a manual reset (MR) input and a +1.25V threshold detector for power-fail input PFI.
