General Description
The TC1272A are cost-effective system supervisor
circuits designed to monitor VDD 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 65 µsec (typ.)
of VDD falling through the reset voltage threshold.
RESET is maintained active for a minimum of
140 msec after VDD rises above the reset threshold.
The TC1272A has a complimentary output. The output
of the TC1272A is valid down to VDD = 1.2V. The
device is available in a 3-Pin SOT-23B package.
The TC1272A device is optimized to reject fast
transient glitches on the VDD line.
