Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings

only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating

conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. All voltage

values are with respect to the network ground terminal unless otherwise noted.

The IC operational charging life is reduced to 20,000 hours, when charging at 1.5A and 125°C. The thermal regulation feature reduces

charge current if the IC’s junction temperature reaches 125°C; thus without a good thermal design the maximum programmed charge

current may not be reached.

This data is based on using the JEDEC High-K board and the exposed die pad is connected to a Cu pad on the board. The pad is

connected to the ground plane by a 2x3 via matrix.
