The MAX809 and MAX810 are cost−effective system supervisorcircuits designed to monitor VCC in digital systems and provide a resetsignal to the host processor when necessary. No external componentsare required.The reset output is driven active within 10 sec of VCC fallingthrough the reset voltage threshold. Reset is maintained active for aminimum of 140 msec after VCC rises above the reset threshold. TheMAX810 has an active−high RESET output while the MAX809 hasan active−low RESET output. Both devices are available in a SOT−23package.The MAX809/810 are optimized to reject fast transient glitches onthe VCC line. Low supply current of 1.0 A (VCC = 3.2 V) makes thesedevices suitable for battery powered applications.
