This data is based on using a JEDEC High-K 4-layer 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 via matrix.

(1)

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.

(2)

All voltages are with respect to PGND if not specified. Currents are positive into, negative out of the specified terminal.

(3)

The bq24155 family can withstand up to 10.6 V continuously and 20 V for a minimum of 432 hours.

The inherent switching noise voltage spikes should not exceed the absolute maximum rating on either the BOOT or SW pins. A tight

layout minimizes switching noise.
