... Data Sheet USB Compliant Li-ion Battery Charger The ISL9219R5360 is a fully integrated high input voltage single-cell Li-ion battery charger. These chargers are fully in compliance with the USB electrical specification. The chargers perform the CC/CV charge function required by Li-ion batteries. The chargers accept an input voltage up to 28V but are disabled when the input voltage exceeds the OVP threshold, to prevent excessive power dissipation ...

... Trickle Charge If the battery voltage is below the trickle charge threshold, the ISL9219R5360 charger delivers a small current to trickle charge the battery until the voltage reaches the fast charge threshold value. The trickle charge threshold is programmed by the resistor connected between the PRECH pin and GND ...
