Figure 45. Undervoltage Detection with Independent Reset Signal Control
This circuit monitors V DD for undervoltage. If the V DD
input falls below the detector threshold (V DET ? ), then the
capacitor on the C D pin will be immediately discharged
resulting in the reset output changing to its active state
indicating that an undervoltage event has been detected. The
addition of a logic gate (Logic 1) provides for reset output
logic gate is tristated the undervoltage detector will behave
normally. If the tristate is de ? asserted, the logic gate will pull
the C D pin low resulting in the Reset Output pin changing to
an active state. This independent control is useful in power
supply sequencing applications when the Reset Output is
tied to the enable input of an LDO or DC ? DC converter.
