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.

ABSOLUTE MAXIMUM RATINGS
Note 1: LX1–LX4 have internal clamp diodes to PGND_, IN1A, and IN1B. Applications that forward bias this diode should take
care not to exceed the power dissipation limits of the device.
Note 2: Package thermal resistance was obtained using the method described in JEDEC specification JESD51-7, using a four-
layer board. For detailed information on package thermal considerations, refer to
