Features & Applications

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 µsec 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 µA 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.
