Description
This is 3-Pin Microprocessor Reset Monitors. MAX809, MAX810 3-Pin Microprocessor Reset Monitors
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 20 sec of VCC falling through the reset voltage threshold. Reset is maintained active for a minimum of 140msec after VCC rises above the reset threshold. The MAX810 has an active high RESET output while the MAX809 has an active low RESET output. The output of the MAX809 is guaranteed valid down to VCC = 1V. Both devices are available in a SOT 23 package. The MAX809, 810 are optimized to reject fast transient glitches on the VCC line. Low supply current of 17 A (VCC = 3.3V) makes these devices suitable for battery powered applications.
