Who designs the first DIY LiFePO4 charger?
Intersil’s ISL78693 is qualified to AEC-Q100 Grade-3, leaks only 3 µA, and is suitable for eCall back-up battery charging. In the event of a crash, eCall systems are intended to automatically broadcast location and contact the nearest 24-hour emergency call center for help. They must “be capable of operating reliably and autonomously from the backup battery at a moment’s notice, even if the vehicle is involved in an accident minutes after being parked for several months,” said Intersil. 3 µA is a maximum, with typical leakage of 700 nA.
