... Startup Designed to operate with single cell Lithium Ion battery voltage, the Si9160 has an operating range of 2 6.0 V. During start-up, the device requires 3 guarantee proper operation, although it will typically start up at less than 2.2 V. Once powered, Si9160 will continue to operate until the voltage at V dead ...
