Controller Chip Enables More Efficient Lithium Battery Production


Analog Devices has launched a controller chip for the manufacturing processes of lithium-ion batteries. The AD8452 increases system accuracy and efficiency for high volume battery testing and formation systems.

The AD8452’s advanced miniaturization and high level of analog precision meet the challenge of mass production of high energy density storage lithium ion packs for transportation and energy storage in homes.

The AD8452 combines a precision analog front-end controller and switch mode power supply (SMPS), pulse-width modulator (PWM) driver into a single silicon platform for high volume battery testing and formation manufacturing.

Compared to conventional technology, the new chip is claimed to provide 50% more channels in the same amount of space, adding capacity and increasing battery production throughput.

“The device is intended for use in battery formation and testing, high-efficiency battery test systems with recycle capability, and in battery conditioning (charging and discharging) systems”, according to the announcement.

The chip uses switching technology that recycles the energy from the battery while discharging and delivers 10 times more accuracy than conventional switching solutions. The higher accuracy allows for more uniform cells within battery packs and contributes to longer living batteries in applications such as electric vehicles.

It also enhances the safety of manufacturing processes by providing better detection and monitoring to help prevent over and undercharging which can lead to battery failures.

The AD8452 delivers bill of material (BoM) cost savings of up to 50% for charging/discharging boards and potential system cost savings of approximately 20%., claims the company.

System simulating demonstration boards will be available to lower R&D engineering cost and shorter time to market for test equipment manufacturers.

Unclonable Security Chip Adds Tough Security To IoT Designs

The AD8452 is in full production, priced at $5.85 each per 1,000, and available in a 48 Lead LQFP package.
