The reset output is driven active within 10µs of power supply falling through the reset voltage threshold. Reset is keeping active for a minimum of 140ms after system power supply has risen above the reset threshold. Reset threshold suitable for operation with variety of supply voltage are available. An independent watchdog output that goes low if the watchdog input has not been toggled within 1.6 seconds. A 1.25V threshold detector for power-fail warning, low-battery detection, or for monitoring a power supply other than +5V. An active-low manual-reset input.
