'Intelligent' power switches for automotive applications

22 October 2003 Power Electronics / Power Management Integrated Solutions

Three new high-side intelligent power switches from International Rectifier feature accurate high frequency current sensing and built-in protection circuits for 14 V automotive applications. The IR3310, IR3311 and IR3312 are designed to enhance reliability and decrease weight in central switching unit light controllers, intelligent glow-plug controls, auxiliary PTC heaters for HVAC systems, engine cooling fan drivers and interior fan controllers. The IR331x family provides accurate current feedback to ±5% at maximum load current over the entire operating temperature range. In PWM controlled applications, the accurate current sensing feature provides the required feedback that enables a microcontroller or ASIC to control the load current. The current feedback bandwidth is 100 kHz, suitable where a low-side switch provides high frequency PWM.
