FM809/810
3-Pin µC Supervisor Circuits
General Description
The FM809/810 are supervisor circuits that monitor power
supply or other system voltages and issue reset pulse whenever
the voltage being monitored is out of tolerance. Once asserted,
the reset pulse is guaranteed to be valid for a minimum of
140ms (256ms typical). FM809xx offers active low push-pull
type of reset while FM810xx offers active high push-pull type.
Several threshold voltages are offered to accommodate 5.0V,
3.3V, 3.0V and 2.7V system voltages.
ꢀ 140ms power-on RESET delay (minimum)
ꢀ RESET operation guaranteed to 1.0V
ꢀ Supply current only 2µA
ꢀ No external components
ꢀ Operating Range
– -40°C to +105°C (SOT23)
– -40°C to +85°C (SC70)
ꢀ SOT23-3 and SC70-3 packages
The low supply current (typically 2 µA)recommends FM809/810
devices for portable designs or wherever power saving is
primary.
Applications
ꢀ Microcontrollers and Microprocessors
These devices are offered in space saving 3-pin SOT23 and
SC70 packages.
ꢀ Appliances
ꢀ Power-Supply Monitoring
ꢀ Portable Equipment
Features
ꢀ Automotive Systems
ꢀ V voltages of 4.63V, 4.38V, 4.00V, 3.08V, 2.93V and 2.63V
