GENERAL DESCRIPTION

The TCM809 and TCM810 are cost-effective system

tems and provide a reset signal to the host processor when

necessary. No external components are required.

falling through the reset voltage threshold. Reset is main-

above the reset threshold. The TCM810 has an active-high

reset output while the TCM809 has an active-low reset

output. The output of the TCM809 is guaranteed valid down

Both devices are available in a

SOT-23B-3 package.

The TCM809/810 are optimized to reject fast transient

powered applications.
