Recommend:
International Rectifier, IR® (NYSE: IRF), a world leader in
power management technology, today introduced the automotive qualified
AUIRS2334S 600V IC for 3-phase inverterized motor drive applications
such as high-voltage compressors (HVAC) and fans.
The AUIRS2334S features an advanced input filter to improve the
input/output pulse symmetry of the signals processed by the device.
Other key features include integrated fixed deadtime protection
circuitry, shoot-through protection circuitry and under-voltage lockout
protection on both the VCC low-side and all VBS high-side floating power
supplies. The new device is also fully characterized for negative
transients on the switching node (NTSOA) that may occur during normal
operation and protection mode.
"With its compact package, high level of integration and comprehensive
set of protection features, the AUIRS2334S offers a smaller, robust
solution for 3-phase inverterized motor drive applications used in
vehicles compared to alternative solutions that use three half-bridge
drivers," said Davide Giacomini, Product Marketing Director, IR's
Automotive Products Business Unit.
Proprietary HVIC and latch immune CMOS technology enables ruggedized
monolithic construction. Logic inputs are compatible with CMOS or LSTTL
outputs, down to 3.3 V. The output drivers feature a high pulse current
buffer stage designed for minimum driver cross-conduction. Propagation
delays are matched to simplify use in high frequency applications. The
floating channel can be used to drive N-channel power MOSFETs or IGBTs
in the high side configuration up to 600 V.
IR's automotive grade IC products are subject to dynamic and static part
average testing combined with 100 percent automated wafer level visual
inspection as part of IR's automotive quality initiative targeting zero
defects. The devices are qualified according to AEC-Q100 standards,
feature an environmentally friendly, lead-free and RoHS compliant bill
of materials.

Availability and Pricing
Pricing for AUIRS2334S begins at US $1.30 each in quantities of
10,000-units. Production quantities are available immediately. The
devices are lead free and RoHS compliant.
Prices are subject to change.
