General Description
The TC1270 and TC1271 are cost-effective system
supervisor circuits designed to monitor VCC 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 reset. No external components
are required.
The reset output is driven active within 20 s (4 s for
F version) of VCC falling through the reset voltage
threshold. Reset is maintained active for a minimum of
140 ms after VCC 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 VCC = 1V. Both devices
are available in a 4-Pin SOT-143 package.
The TC1270/TC1271 devices are optimized to reject
fast transient glitches on the VCC line. Low supply
current of 7 A (VCC = 3.3V) makes these devices
suitable for battery powered applications.
