Industrys most accurate Li-Ion battery charger integrated circuits
(Technology News, 21 Feb 2008 )
Three new power management ICs can be factory-customized to support hundreds of application-specific configurations for ultra-mobile devices
(max limit of 1200While lithium-ion (Li-Ion) batteries offer many advantages for portable consumer electronics, they require extremely accurate charging current and output voltages to optimize battery life and performance. To address this need, Freescale Semiconductor has introduced a family of Li?Ion battery charger ICs designed to provide the industrys highest performance and accuracy, as well as exceptional configuration flexibility.

The ICs can be customized to create hundreds of configurations to address a wide range of portable and ultra-mobile device needs. A designer can select features and specifications, such as pin-out, feature set, charging parameters and LED indication, and Freescale can deliver customized charger ICs by programming them at the end of the manufacturing process.
The programming flexibility of the Li-Ion battery charger devices enables Freescale to create highly tailored charger ICs for specific application requirements. Target applications for Freescales battery charger IC family include cell phones, personal media players, navigation systems, digital still cameras, as well as travel chargers for these devices.
ixels) Body Text Built using Freescales advanced SMARTMOS process technology, the battery charger ICs are designed to deliver up to 1.2A of charge current to single cell Li?Ion or Li?Polymer batteries. The battery charger input voltage can come from an AC adapter or a USB port power source. The high input voltage capability (up to 28V) is designed to eliminate the need for an external input over-voltage protection circuit required in handheld devices, which helps reduce system cost and board space.
To provide developers with smaller, lighter charger IC products for space-constrained portable designs, each battery charger IC comes in a low-profile 2x3x0.65 mm ultra-thin dual flat no-lead (UDFN) thermally-enhanced package.
