International Rectifier has introduced a family of fully-protected, high-side intelligent power switches (IPS). The IPS60xx family is designed for tough automotive applications, including transmission and gearbox, solenoid drivers; lighting control; and brushed DC motor control for seats, window lifts, and wipers. The full-featured IPS6011 delivers a maximum on-state resistance of 14mOhms in a DPak. The IPS60xxPBF family integrates power MOSFETs with a host of standard protection features for over-current, over-temperature, ESD, and active clamp. An integrated charge pump allows the device to be driven in high-side topologies without additional components.

The family also features reverse battery protection, actively turning on the output MOSFET during a reverse battery event. This feature almost eliminates current flow through the body diode and significantly reduces power dissipation in the part during an event, improving reliability and again eliminating the need for more components. Finally, these devices provide diagnostic feedback to the microcontroller, allowing detection of basic faults such as open load and short circuit. All devices are RoHs compliant and Q100-qualified for automotive applications and are available in a variety of packages.
