Intelligent power switch with active di/dt
control for automotive motor driver
International Rectifier has introduced the AUIR3330S Intelligent
Power Switch (IPS) with a proprietary active di/dt control
feature to reduce conducted EMI and switching in automotive
motor drive applications.
The new 40 V high-side device packs bootstrap regulator,
charge pump and high-side driver into a single device. The
load can be driven up to 40 kHz at 100 percent of duty cycle.
The other features of AUIR3330S include programmable over-current
and over-temperature protection required by applications
operating in harsh automotive environments such as pumps
and fans. The AUIR3330S also features current sensing feedback,
a diagnostic function, very low current consumption in sleep
mode and ESD protection.
"IR's innovative active di/dt control drastically
reduces conducted EMI on the input supply without increasing
switching losses, enabling a reduction in the size of the
EMI filter and the heat sink for more efficient compact
motor systems," said David Jacquinod, product marketing
manager, IR's Automotive Products Business Unit.
The device is qualified according to AEC-Q100 standards
and is RoHS compliant.
