PT7M7438 Applications
* (VCC ≥1.8V). When the power-supply voltage drops below the specified low threshold, the low-battery output asserts (see Low-Battery Output). When the voltage rises above the specified high threshold following a 90ms (min) time-out period, the lowbattery output is deasserted (see Threshold Monitoring
