IR Introduces New Intelligent Power Switches for Automotive Applications
International Rectifier Corp. (IR)® introduced a new family of fully-protected, high-side intelligent power switches (IPS) that leverage next-generation silicon in enhanced packaging to deliver improved power density and response times. The new 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.
"Our new fully protected single-chip devices deliver impressive gains in RDS(on) and consume much less board area for the overall solution. For example, the full-featured IPS6011 delivers a maximum on-state resistance of 14mΩ in a DPak," said Anthony Murray, IR’s Technical Marketing Manager for Automotive Components.
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 new IPS 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, the new IPS 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.
The new devices are available immediately. Pricing begins at US $1.78 each for the IPS6011, US $1.18 each for the IPS6021, US $.95 each for the IPS6031 and US $0.65 each for the IPS6041, all in 10,000-unit quantities.
