Product Summary
The MAX707ESA+ is a cost-effective system supervisor circuit 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 MAX707ESA+ has a low quiescent current of 12μA 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 MAX707ESA+ has a Manual Reset MR input and a +1.25 V threshold detector for power;fail input PFI. Applications include Computers, Embedded System, Battery Powered Equipment and Critical μP Power Supply Monitor.
