P 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 sec 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
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.
