General Description
The TCM809 and TCM810 are cost-effective system
supervisor circuits designed to monitor V
DD
in digital
systems; providing a reset signal to the host processor,
when necessary. No external components are
required.
The RESET output is typically driven active within
65 μsec of V
DD
falling through the reset voltage thresh-
old. RESET is maintained active for a minimum of
140 msec after V
DD
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/TCM810 is valid down to
V
DD
= 1V. Both devices are available in 3-Pin SC-70
and SOT-23B packages.
The TCM809/TCM810 are optimized to reject fast
transient glitches on the V
DD
line. A low supply current
of 9 μA (typ., V
DD
= 3.3V) make these devices suitable
for battery-powered applications.
