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.
The reset output is driven active within 20
μ
sec of V
CC
falling through the reset voltage threshold. RESET is
maintained active for a minimum of 100msec after V
CC
rises above the reset threshold. The TC1277 has an
active-high RESET output while the TC1275 and
TC1276 have an active-low RESET output. TC1275
and TC1277 each have a complimentary output while
the TC1276 has an open drain output. The output of the
TC1275 and TC1276 is valid down to V
CC
= 1.2V. The
TC1277 is valid down to V
CC
= 1.8V. All three devices
are available in a 3-Pin SOT-23B package.
TC1275/TC1276/TC1277
are
cost-effective
The TC1275/TC1276/TC1277 devices are optimized to
reject fast transient glitches on the V
CC
line.
