General Description
The TC1270 and TC1271 are cost-effective system
supervisor circuits designed to monitor V
CC
in digital
systems and provide a reset signal to the host
processor when necessary. A manual reset input is
provided to override the reset monitor, and is suitable
for
use
as
a
push-button
components are required.
The reset output is driven active within 20
μ
sec (4
μ
sec
for F version) of V
CC
falling through the reset voltage
threshold. RESET is maintained active for a minimum
of 140msec after V
CC
rises above the reset threshold.
The TC1271 has an active-high RESET output while
the TC1270 has an active-low RESET output. The
output of the TC1270 is valid down to V
CC
= 1V. Both
devices are available in a 4-Pin SOT-143 package.
