PARAMETER
GENERAL
Input Voltage Range
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.
Continuous Power Dissipation (T
A
=+70°C)
32-Pin Thin QFN (derate 22mW/°C
above +70

C).............................................................1700mW
Operating Temperature Range ...........................-40°C to +85°C
Junction Temperature......................................................+150°C
Storage Temperature Range.............................-65°C to +150°C
Lead Temperature (soldering, 10s).................................+300°C
Note 1:
LXSU has internal clamp diodes to OUTSU and PGND, and LXSD has internal clamp diodes to INSD and PGND.
Applications that forward bias these diodes should take care not to exceed the devices power dissipation limits.
