TCM809/TCM810
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 ...
