  • 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 ?A 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.
