Avago Technologies Expands Line of Optocouplers for Hybrid Electric Automobiles
Effectively Applies Expertise in Optical Isolation for Stringent Automotive Requirements
SAN JOSE, Calif., November 27, 2007 - Avago Technologies today announced the latest addition to its optocouplers family which targets the hybrid electric vehicle (HEV) market. The company is a leading supplier of analog interface components for communications, industrial and consumer applications. Avago's new automotive-grade ACPL-M46T is a 1MBd Intelligent Power Module (IPM) digital interface optocoupler designed for HEVs applications and offers high reliability, high performance, ease of integration and superior heat dissipation.
The ACPL-M46T requires a low input LED drive current (10mA) that provides longer operating life and performance specified for automotive intelligent power module (IPM) applications over a wide temperature range of -40°C to 125°C. Optimized for the HEV market, Avago's new optocoupler is qualified to meet automotive AEC-Q100 semiconductor stress test guidelines. The ACPL-M46T also delivers a maximum propagation delay difference that enables a circuit designer to reduce switching dead time and improve inverter efficiency. In addition, Avago's ACPL-M46T offers excellent common mode transient rate (CMR) of 15kV/?s at VCM = 1500V which prevents erroneous driving of the IPM interface and ensures reliable operation under noisy operating environments.
Due to the high number of electrical components in hybrid electric vehicles, optoisolation products play a key role in the optimal performance of these cars. The use of optocouplers in HEV ensures electrical safety and integrity of the automobile while it is in operation.
Avago's new automotive-grade digital optocoupler is RoHS compliant and comes housed in a surface mount, SO-5 package. The device comes with an enhanced LED (10 mA) for lower driving current and lower power consumption. This IPM optocoupler has an enhanced wire bonding processes and an improved lead frame for added reliability and better heat dissipation. A high common-mode rejection ratio provides a high immunity to transient noises, EMI and ground loops eliminations. Its compact size also makes it flexible for high-density automotive system design.
U.S. Pricing and Availability
Pricing for Avago's ACPL-M46T begins at $2.38 each for 10,000 volumes. This product is available now through Avago's direct sales channel and worldwide distribution partners.
