Effective use of power integrated circuit packages in automotive systems requires thermal models. This paper provides detailed information on the transient and steady state characterization and modeling of power SOIC packages. Sixteen and twenty four pin wide body SOICs are analyzed in FR4 and polyimide systems. Model extraction, generation, and validation are presented. To validate the model, data taken in an electronic fuel injection system is analyzed and then compared to the simulation results. The model results show 3 % correlation to the actual data.

This paper describes a series of power ICs designed specifically for powertrain control applications. The series includes low-side drivers and high-side drivers. The drivers are capable of fault detection and reporting to the Micro-Control Unit (MCU). Reported faults include short circuit detection, thermal limit, over-voltage protection, “on” open load detection, and “off” open load detection.

A SMARTMOS™ power integrated circuit has been developed for diagnostic testing in vehicles. The SMARTMOS™ process is ideal for this application because of its robustness to temperature and voltage extremes. The IC serves as an interface between logic level microcontrollers and battery level testers. It is fully compatible with the ISO 9141 requirement for the interchange of digital information in vehicle diagnostic systems.
