General Description
The TCM809 and TCM810 are cost effective system
supervisor circuits designed to monitor VDD in digital
systems and provide a reset signal to the host proces-
sor when necessary. No external components are
required.
The RESET output is typically driven active within
20 sec (SOT-23) or 65 sec (SC-70) of VDD falling
through the reset voltage threshold. RESET is main-
tained active for a minimum of 140 msec after VDD
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 VDD = 1V. Both devices are
available in 3-Pin SOT-23B and SC-70 packages.
The TCM809/TCM810 are optimized to reject fast tran-
sient glitches on the VDD line. Low supply current of
9 A (typ., VDD = 3.3V) makes these devices suitable
for battery powered applications.
