ABSOLUTE MAXIMUM RATINGS
These are stress ratings only and functional operation
of the device at these ratings or any other above those
indicated in the operation sections of the specifications
below is not implied. Exposure to absolute maximum
rating conditions for extended periods of time may
affect reliability.

BST .................................................................. 13.2V
BST-SWN .............................................................. 7V
All other pins ................................ -0.3V to V CC + 0.3V
Peak Output Current < 10 μ s
GH,GL .................................................................. 2A
Storage Temperature ........................ -65 ° C to 150 ° C
Power Dissipation
