LTC4010CFE#PBF

LTC4010 is 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. It automatically senses the presence of a DC adapter and battery insertion or removal. When an external DC source is not present, this device 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. 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. 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.
