GENERAL DESCRIPTION
The TC1272, TC1273 and TC1274 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 main-
tained active for a minimum of 100msec after VCC 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 output while the TC1273 has an open
drain output. The output of the TC1272 and TC1273 is
guaranteed valid down to VCC = 1.2V. The TC1274 is
guaranteed valid down to VCC =1.8 V. All three devices are
available in a 3-Pin SOT-23B package.
The TC1272/3/4 are optimized to reject fast transient
glitches on the VCC line.
