在使用Intersil的功率BiCMOS低边驱动器时关于热量

The Intersil HIP0080, HIP0081, HIP0082 and CA3282
Power BiMOS Low Side Drivers are designed for use in
automotive and industrial switching applications over an
operating temperature range of -40oC to +125oC. Each circuit
has enhanced performance features that include logic level
operation, overload protection and diagnostic feedback by
serial interface. The focus of this Application Note is directed to
the HIP0082 Power BiMOS Quad Low Side Driver but generally
applies to all of the MOS Low Side Drivers. The IC interface
and switching configurations are noted in the Block Diagrams
below. The CA3282, HIP0081 and HIP0082 are provided in a
15 Lead Power Package with a low junction-to-case thermal
resistance and a lead form option for vertical or surface mount.
The chip is directly mounted on the copper heat sink tab of the
IC to provide a maximum qJC that is less than 3oC/W.
