General Description
The
system supervisor circuits designed to monitor V
CC
in
digital systems and provide a reset signal to the host
processor when necessary. No external components
are required.
TC1272/TC1273/TC1274
are
cost-effective
The reset output is driven active within 20 μsec of V
CC
falling through the reset voltage threshold. RESET is
maintained active for a minimum of 100 msec after
V
CC
rises above the reset threshold. The TC1274 has
an active-high RESET output, while the TC1272 and
TC1273 have an active-low RESET output. The
TC1272 and TC1274 each have a complimentary out-
put, while the TC1273 has an open-drain output. The
output of the TC1272 and TC1273 is valid down to V
CC
= 1.2V. The TC1274 is valid down to V
CC
= 1.8V. All
three devices are available in a 3-Pin SOT-23B
package.
The TC1272/TC1273/TC1274 devices are optimized to
reject fast transient glitches on the V
CC
line.
