4A Li-Ion Battery Charger Accepts Inputs to 32V
Rick Brewster Advances in Li-ion battery technologies continue to produce batteries with increased
capacity and energy density. Charge/discharge rate capabilities are also rising,
sometimes to multiple C rates (C is the standard designator for battery capacity
stated in amp-hrs). These technologies are making their way into consumer,
automotive, medical and industrial markets. In most cases, the charger must
be able to recharge multiple sources over a wide range of input voltages.
High capacity/current batteries require
chargers that handle the high currents
safely, efficiently and cost effectively.
Until now, building a safe high current battery charger required the use
of multiple ICs and a host of external
components resulting in expensive and
bulky solutions. The LT3651 integrated
battery charger solves this problem
by supporting charge currents up to
4A and accepting input voltages to 32V.
BATTERY CHARGER FEATURES Charger safety is a significant concern
as batteries increase in capacity. The
LT3651 includes all of the necessary charge
termination and protection features.
Charge termination methods include
C/10 termination or safety timer termination. Additional protection features …
