ISL9219 Li-ion Battery Charger

ISL9219 Li-ion Battery Charger The ISL9219 is a fully integrated high input voltage single-cell Li-ion battery charger. This charger is fully in compliance with the USB electrical specification. The charger performs the CC/CV charge function required by Li-ion batteries. The charger accepts an input voltage up to 28V but is disabled when the input voltage exceeds the OVP threshold, typically 6V, to prevent excessive power dissipation. The 28V rating eliminates the overvoltage protection circuit.

ISL9219 Features

* include an OVP protected power-good source, preconditioning of an over-discharged battery, an NTC thermistor interface for charging the battery in a safe temperature range, automatic recharge, and thermally enhanced QFN package. Ordering Information PART NUMBER PART TEMP. PKG. MARKING RANGE (°
