Max Continuous Current into Any Pin (Note 1)................±20mA

Max Continuous Current into SWn Pin (Note 2)............±400mA

Max Average Power for ESD Diodes (Note 3)............. 14.4/√τW

Package Continuous Power (Note 4)............................2000mW

Package Junction-to-Ambient

Thermal Resistance (θJA) .............................................40°C/W

Operating Temperature Range......................... -40°C to +125°C

Storage Temperature Range............................ -55°C to +150°C

Junction Temperature (continuous)...................................150°C

Soldering Lead Temperature (10s max)............................300°C

Note 1: Balancing switches disabled.

Note 2: One balancing switch enabled, 60s (max).

Note 3: Average power for time period τ where τ is the time constant (in μs) of the transient diode current during a hot-plug event.

For, example, if τ is 330μs, the maximum average power is 0.793W. Peak current must never exceed 2A. Actual average

power during hot-plug must be calculated from the diode current waveform for the application circuit and compared to the

maximum rating.

Note 4: Multilayer board. For TA > +70°C derate 25mW/°C.

Absolute Maximum Ratings

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.
