m P Supervisory Circuits
The MAX707/708 are cost?effective system supervisor circuits
designed to monitor V CC 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 m sec of V CC falling
through the reset voltage threshold. Reset is maintained with 200 mS
of delay time after V CC rise above the reset threshold. The
MAX707/708 have a low quiescent current of 12 mA at V CC = 3.3 V,
an active?high RESET and active?low RESET with a push?pull

output. The output is guaranteed v ali d down to V CC = 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.
