Abstract
An intelligent power MOSFET with built-in reverse battery protection, which is essential for automotive power switches, has been developed. The reverse battery protection is achieved without using external control signals. This new power MOSFET can replace the conventional three-terminal power MOSFETs used in automotive applications. Its positive drain breakdown voltage is 71 V and the negative drain current at a drain voltage of -16 V is only -750 /spl mu/A. On resistance is 170 m/spl Omega/. Using the latest fabrication process now available for commercial products, the on-resistance can be reduced to less than 50 m /spl Omega/ in a TO-220 package.
