ADI’s AD8452 is a highly integrated precision analog front end, controller, and SMPS PWM-driver for high volume battery testing and formation manufacturing. A precision instrumentation amplifier measures the battery charge/discharge current to better than ±0.1% accuracy while an equally accurate difference-amplifier measures the battery voltage. The AD8452 simplifies designs by providing excellent performance, functionality, and overall reliability in a space-saving 48-lead, 7 mm x 7 mm x 1.4 mm LQFP package.

The AD8452’s higher level of integration and ease-of-use enable the implementation of power recycling with 50% more channels, lowering system cost, and increasing more testing capacity in the same space. The device is ideal for Li-ion battery formation and testing.
