General Description
The TC1278/TC1279 are cost-effective system super-
visor circuits designed to monitor V
CC
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 5
μ
sec of V
CC
falling through the reset voltage threshold. RESET is
maintained active for a minimum of 250msec after V
CC
rises above the reset threshold. The TC1278 has an
active-high RESET output while the TC1279 has an
active-low RESET output, and both devices have an
open drain output stage. The output is valid down to
V
CC
= 1.2V. Both devices are available in a 3-Pin SOT-
23B package.
