Package Type
General Description
The
TC1275/TC1276/TC1277
are
cost-effective
system supervisor circuits designed to monitor VCC 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
sec of VCC
falling through the reset voltage threshold. RESET is
maintained active for a minimum of 100msec after VCC
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 VCC =1.2V. The
TC1277 is valid down to VCC = 1.8V. All three devices
are available in a 3-Pin SOT-23B package.
The TC1275/TC1276/TC1277 devices are optimized to
reject fast transient glitches on the VCC line.
