Typical Applications

• Computers

• Embedded Systems

• Battery Powered Equipment

• Critical µP Power Supply Monitoring

The MAX809 and MAX810 are cost–effective system supervisor circuits designed to monitor V_CCin 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 V_CCfalling through the reset voltage threshold. Reset is main-

tained active for a minimum of 140msec after V_CCrises 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 V_CC= 1V. Both devices are available in a SOT–23 package.

The MAX809/810 are optimized to reject fast transient glitches on the V_CCline. Low supply current of 17µA (V_CC

3.3V) makes these devices suitable for battery powered applications.
