ISL6292B
Li-ion/Li Polymer Battery Charger
The ISL6292B uses Intersil’s
patent-pending
dual-mode
charge technology to minimize the heat in a linear charger.
The ISL6292B is a modification of the original ISL6292 and
is optimized for cellular phone travel charger applications.
The low-heat generation feature of the dual-mode charger
enables the charger IC to be placed inside the connector of
the travel charger to completely remove the influence of the
adapter cable on the charging performance.
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 tri-color LED. A safety timer prevents
charging a dead battery for an excessively long period.
The ISL6292B also features 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, one for during charge
and one for not during charge. The thermally-enhanced QFN
package further improves the thermal performance of the
ISL6292B in space-limited applications.
