Stresses beyond those listed in this table may cause permanent damage to the device. The Absolute Maximum ratings are stress ratings only, and functional operation of

the device at these or any other conditions beyond those indicated in the Electrical Characteristics table is not implied. Exposure to Absolute Maximum-rated conditions

for extended periods may affect device reliability.

2

All voltages referenced to AGND.

3

The SW pin has internal clamp diodes to GND. Applications that forward bias this diode should take care not to exceed the IC package power dissipation limits. Note:

Exact energy specification to be determined.

4

The switch DMOS is self-protected. If voltage spikes exceeding 40 V are applied, the device would conduct and absorb the energy safely.
