TC1272A
3-Pin Reset Monitor
Features 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. Precision VDD Monitor
140 msec Minimum RESET, Output Duration
Output Valid to VDD = 1.2V
VDD Transient Immunity
Small 3-Pin SOT-23B Package
No External Components Applications Computers
Embedded Systems
Battery-Powered Equipment
Critical ВµP Power Supply Monitoring The reset output is driven active within 65 Вµsec (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. Package Type Typical Application Circuit 3-Pin SOT-23B* VDD
