ISL6297
Li-ion/Li Polymer Battery Charger
The ISL6297 is a Dual-Mode Lithium Ion battery charger
optimized for cellular phone travel charger applications. It
uses Intersil’s
patent-pending
dual-mode charge
technology to minimize the heat normally generated in a
linear charger. By minimizing the heat generation, the
ISL6297 can be placed inside the connector of the travel
charger to completely remove the influence of the adapter
cable on the charging performance.
The ISL6297 is an enhancement of the original ISL6292B.
New features include improved accuracy, pre-charge circuit
verification, and enhanced LED indicator function.
Working with a current-limited AC/DC converter, the dual-
mode charger charges a Li-ion battery with the same current
profile as a traditional linear charger. The constant charge
current is determined by the current limit of the AC/DC
converter. The constant output voltage is fixed at 4.2V. When
the battery voltage is below 2.8V, the charger preconditions
the battery with a low trickle-charge current. The charge
status is indicated by a bi-color LED. A safety timer prevents
charging a dead battery for an excessively long period.
The ISL6297 also features THERMAGUARD, a thermal
foldback function that automatically reduces the charge
current when the internal die temperature exceeds a 100°C
limit to prevent further temperature rise. This function
removes the concern of thermal failure in the targeted
space-limited applications. An ambient temperature
monitoring circuit allows users to set two separate
temperature limit levels, for charge and non-charge
conditions. The thermally-enhanced QFN package further
improves the thermal performance of the ISL6297 in space-
limited applications.
