Programmable Battery Charger Ic

If the charger is left connected to the battery a periodic top up charge is applied to counteract battery self discharge.

Programmable battery charger ic.

Electro labs has posted a new project about making a programmable lithium battery charger shield for arduino. The bq2000 is a programmable monolithic ic for fast charge management of nickel cadmium nicd nickel metal hydride nimh or lithium ion li ion batteries in single or multi chemistry applications. The bq24401 provides these charge termination criteria. These battery charger ics are offered in linear or switching topologies and are completely autonomous in operation.

Summit microelectronics has expanded its third generation programmable battery charger integrated circuit ic family for single cell li ion li polymer and li fepo4 powered systems. Intelligent battery charger for nimh li ion. In essence an i 2 c programmable battery charger allows the user to charge almost every lithium based battery due to the flexibility of programming different charging parameters. The shield schematic and printed circuit board are designed using the solopcb tools a windows based pcb designing tool from fabstream the charger shield consists of a nokia 5110 lcd and four tact switches for user interface which allows users to program the charging voltage and current.
