EL SEGUNDO, CA. October 1998 - International Rectifier, the power experts, now offers a comprehensive family of Intelligent Power Switches (IPS) for low-side and high-side power distribution in high-reliability systems with supply voltages from 4.5 to 50V.

These new devices on one end offer highest density packaging, while at the other end of the spectrum they offer the highest load current handling capability at the lowest on-resistance (R_DS(on)). With over-temperature, over-voltage and over-current protection for ease of circuit design and design ruggedness, the new IPS products are ideal for use in high density applications such as automotive junction boxes, active suspension, engine control systems and anti-lock brakes, and in high current applications like direct injectors, glow plugs, head lamps and pump motors.

"Our new IPS are ideal replacements for electromechanical relays," said David Tam, director of control products at IR. "With all of the integrated protection features, the IPS eliminate the need for extra components to reduce systems cost, and offer the ruggedness to significantly reduce warranty returns and expenses."

Technical breakthroughs for the IPS family include a novel level-shifted active clamp design that allows these devices to act as active switches even during re-circulation of inductive energy. All also employ low noise charge pumps with controlled turn-on/off characteristics to offer the best low EMI specifications in the industry. Detailed IPS specifications include:
