Intersil Corporation announced the ISL78692, a 4.1V single-cell battery charger designed to extend the life of lithium-ion (Li-ion) batteries in automotive emergency call
(eCall) systems. The ISL78692 battery charger dissipates lower leakage current (3uA) than competing solutions, allowing the backup battery to remain charged for a longer period of time. Lower charging voltage also extends battery life while the device’s small footprint reduces total solution size. Vehicles equipped with eCall systems automatically place a call to an emergency service center in the event of an accident. The ISL78692 Li-ion battery charger is designed to support emerging worldwide emergency call systems such as Europe’s eCall initiative, which brings rapid assistance to motorists involved in a collision anywhere in the European Union, and OnStar®, which provides a safety and security service in the United States.
