在使用Intersil的功率BiCMOS低邊驅(qū)動器時關(guān)于熱量

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.
