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 in the operational sections of the specifications is not implied.
Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
2. Device are ESD sensitive. Handling precaution recommended. The Human Body model is a 100pF
capacitor discharged through a 1.5KΩ resistor into each pin.

1. Due to PGND1 and PGND2 are bound to the bottom of the package, it should be noted
that the bottom must be laid together with GND.
2. On the PCB, a hole should be placed in the location of the package bottom for debug
issue.
