MAX707, MAX708

mP Supervisory Circuits

The MAX707/708 are cost–effective system supervisor circuits

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 msec of Vcc falling

through the reset voltage threshold. Reset is maintained with 200 mS

of delay time after Vcc rise above the reset threshold. The

MAX707/708 have a low quiescent current of 12 mA at Vcc = 3.3 V, an

active–high RESET and active–low RESET with a push–pull output.

The output is guaranteed valid down to Vcc = 1.0 V. The

MAX707/708 have a Manual Reset MR input and a +1.25 V threshold

detector for power–fail input PFI. These devices are available in a

Micro8 and SOIC–8 package.
