MAX809TTRG SOT-23-3 Supervisory Circuits 3.08V uP Reset

The MAX809 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 sec 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 A (VCC = 3.2 V) makes these
devices suitable for battery powered applications.
