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

µsec of V

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

MAX810 has an active–high RESET output while the MAX809 has

an active–low RESET output. The output of the MAX809 is

SOT–23 package.

The MAX809/810 are optimized to reject fast transient glitches on

µA (V

devices suitable for battery powered applications.
