The TLVxHx90-SEP family of comparators enable quick decision-making based on monitored signals. These components can rapidly detect whether a measured voltage—either from a rail or the output of a current sensor—is out of specification.

For example:

• The TLV4H290-SEP provides four independent comparator channels with a propagation delay of less than 0.1µs, while consuming only 25µA per channel in quiescent current.
• The TLV4H390-SEP delivers the same performance with open-drain outputs, making it easy to aggregate multiple fault signals into a single alarm line.
