LTC4011 is a high efficiency standalone nickel battery charger. It provides 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. This device automatically senses the presence of a DC adapter and battery insertion or removal. Heavily discharged batteries are precharged with a trickle current. It 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. It is used in applications such as integrated or standalone battery charger, portable instruments or consumer products, battery-powered diagnostics and control, back-up battery management etc.
