MAX809 Very Low Supply Current 3-Pin Microprocessor Reset Monitors

Pin No. Symbol 1 GND 2 RESET (MAX809) 2 RESET (MAX810) 3 VCC Description Ground RESET output remains low while VCC is below the reset voltage threshold, and for a reset timeout period after VCC rises above reset threshold RESET output remains high while VCC is below the reset voltage thre.

DATA SHEET www.onsemi.com Very Low Supply Current 3-Pin Microprocessor Reset Monitors MAX809 Series, MAX810 Series The MAX809 and MAX810 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 10 msec of VCC falling through the reset voltage threshold. Reset is maintained active for a timeout period which is trim.
