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 exter-
nal DC source is not present, the LTC4010 enters shut-
down 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
termination 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 tempera-
ture limits. NiMH or NiCd fast charge termination param-
eters are pin selectable.
