    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
