Application Information

Multiple Supplies

Mainly, the pull-up connected to the RT9818 will connect

to the supply voltage that is being monitored at the IC's

VDD pin. However, some systems may use the open-

drain output to level-shift from the monitored supply to

reset circuitry powered by some other supply.

Benefits of Highly Accurate Reset Threshold

Most

μP supervisor ICs have reset threshold voltages

between 1% and 1.5% below the value of nominal supply

voltages. This ensures a reset will not occur within 1% of

the nominal supply, but will occur when the supply is 1.5%

below nominal.
