GENERAL DESCRIPTION
The TCM809 and TCM810 are cost-effective system
supervisor circuits designed to monitor V
CC
in digital sys-
tems and provide a reset signal to the host processor when
necessary. No external components are required.
The reset output is driven active within 20
µsec
of V
CC
falling through the reset voltage threshold. Reset is main-
tained active for a minimum of 140msec after V
CC
rises
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
to V
CC
= 1V. Both devices are available in 3-Pin SOT-23B
and SC-70 packages.
The TCM809/810 are optimized to reject fast transient
glitches on the V
CC
line. Low supply current of 12µA (V
CC
=
3.3V) makes these devices suitable for battery powered
applications.
