Freescale has introduced three new power management ICs that can be factory-customized to support hundreds of application-specific configurations for ultramobile devices. While 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's new family of Li-Ion battery charger ICs provide high performance and accuracy, as well as exceptional configuration flexibility.

Freescale's MC34671, MC34673 and MC34674 are single-input autonomous battery charger ICs that exhibit output voltage accuracy of 0.4 percent over temperature and charging current accuracy of 5 percent over temperature. The ICs can be customized to create hundreds of configurations to address a wide range of portable and ultramobile device needs.

A designer can select features and specifications, such as pin-out, feature set, charging parameters and LED indication, and then Freescale can deliver customized charger ICs by programming them at the end of the manufacturing process.

Built using Freescale's advanced SMARTMOS process technology, the battery charger ICs are designed to deliver up to 1.2 amperes 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 28 V — is designed to eliminate the need for an external input overvoltage protection circuit required in handheld devices, which helps reduce system cost and board space.

Each battery charger IC is packaged in a low-profile, 2-mm x 3-mm x 0.65-mm, ultrathin dual flat, no-lead, thermally enhanced package.

Samples of the battery charger ICs are available.
