Absolute maximum ratings

The maximum continuous charger voltage must be less than 5.5 V. The overvoltage protection

(OVP) circuit will help protect against transients above this level minimising effects on operation

lifetime.

VDDOUT must not be driven from an external supply if the charger buck is used.

Note 1

Stresses beyond those listed under

‘Absolute maximum ratings’ may cause permanent damage to the

device. These are stress ratings only, so functional operation of the device at these or any other

conditions beyond those indicated in the operational sections of the specification are not implied.

Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Note 2

JEDEC 6 layer board, still air, influenced by PCB technology and layout. The numbers of supplies that

can be used at the same time at maximum dissipation power is limited by the thermal resistance of the

package and the PCB layout.
