MAX809 Series,
MAX810 Series
Very Low Supply Current
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.

DIAGRAM
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 trimmed by the factory after VCC rises above
the reset threshold. The MAX810 has an active−high RESET output
while the MAX809 has an active−low RESET output. Both devices
are available in SOT−23 and SC−70 packages.

The MAX809/810 are optimized to reject fast transient glitches on
the VCC line. Low supply current of 0.5 mA (VCC = 3.2 V) makes these
devices suitable for battery powered applications.
