ISL78693 - Automotive Single-Cell LiFePO4 Battery Charger
ISL78693 Automotive Single-Cell LiFePO4 Battery Charger The ISL78693 is an integrated single-cell Li-ion or Li-polymer battery charger capable of operating with an input voltage as low as 2.65V (cold crank case).
This charger is designed to work with various types of AC adapters or a USB port.
The ISL78693 operates as a linear charger when the AC adapter is a voltage source.
The battery is charged in a Constant Current/Constant Voltage (CC/CV) profile.
The charge current is programmable with an
ISL78693 Features
* charge current thermal foldback to ensure safe operation when the printed circuit board’s thermal dissipation is limited due to space constraints. Additional features include preconditioning of an over-discharged battery, an NTC thermistor interface for charging the battery in a safe temperature ran
