    3-Pin Microcontroller Reset Monitors
    Features General Description Precision VDD Monitor for 2.5V, 3.0V, 3.3V, 5.0V
    Nominal System Voltage Supplies 140 msec Minimum RESET Time-Out Period RESET Output to VDD = 1.0V (TCM809) Low Supply Current, 9 ВµA (typ.) VDD Transient Immunity Small 3-Pin SC-70 and SOT-23B Packages No External Components Push-Pull RESET Output Temperature Ranges:
    -Industrial: SC-70 (E): -40п‚°C to +85п‚°C
    -Extended: SOT-23, SC-70 (V): -40п‚°C to +125п‚°C The TCM809 and TCM810 are cost-effective system
    supervisor circuits designed to monitor VDD in digital
    systems; providing a reset signal to the host processor,
    when necessary. No external components are
    required. Applications Computers
    Embedded Systems
    Battery-powered Equipment
    Critical Microcontroller Power Supply Monitoring
    Automotive The RESET output is typically driven active within
    65 Вµsec 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 TCM810 has an active-high RESET output, while
    the TCM809 has an active-low RESET output. The
    output of the TCM809/TCM810 is valid down to
    VDD = 1V. Both devices are available in 3-Pin SC-70
    and SOT-23B packages.
    The TCM809/TCM810 are optimized to reject fast
    transient glitches on the VDD line. A low supply current ...
