... For applications requiring open-drain output, see MIC2778/ MIC833. The IC’s power supply input is separate from the detector inputs, allowing the MIC2779 to be powered from a down- stream supply, such a boost converter. Supply current is extremely low (1 A, typical), making it ideal for portable applications. ...

... Upon being replaced, or being recharged above a second higher pro- grammed trip point, the output remains low (MIC2779L) or high (MIC2779H) for a minimum of 140ms and then sends a reset signal to a microprocessor or other downstream com- ponent. See “Timing Diagram.” ...

... As shown in Figure 2, the narrower the transient, the deeper the threshold overdrive that will be ignored by the MIC2779. The graph represents the typical allowable transient duration for a given amount of threshold overdrive that will not gener- ate a reset ...
