DESCRIPTION
The LTC ? 4010 provides a complete, cost-effective nickel
battery fast charge solution in a small package using few
external components. A 550kHz PWM current source
controller and all necessary charge initiation, monitoring
and termination control circuitry are included.
The LTC4010 automatically senses the presence of a DC
adapter and battery insertion or removal. When an external
DC source is not present, the LTC4010 enters shutdown
and supply current drawn from an installed battery drops
to the lowest possible level. Heavily discharged batteries
are precharged with a trickle current. The LTC4010 can
simultaneously use both –?V and ?T/?t fast charge ter-
mination techniques and can detect various battery faults.
If necessary, a top-off charge is automatically applied to
NiMH batteries after fast charging is completed. The IC
will also resume charging if the battery self-discharges
after a full charge cycle.
All LTC4010 charging operations are qualified by actual
charge time and maximum average cell voltage. Charging
may also be gated by minimum and maximum temperature
limits. NiMH or NiCd fast charge termination parameters
are pin selectable.
