MAX809S/D

MAX809 Series,

MAX810 Series

Very Low Supply Current

3−Pin Microprocessor

Reset Monitors

The MAX809 and MAX810 are cost−effective system supervisor

signal to the host processor when necessary. No external components

are required.

The reset output is driven active within 10

through the reset voltage threshold. Reset is maintained active for a

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

devices suitable for battery powered applications.
