Avago Technologies announced three new high-voltage line drivers that augment its offerings for the industrial automation market. The AEIC-7272, AEIC-7273 and AEIC-2631 quad differential line drivers provide the additional supply voltage required for industrial applications, up to 30V. With integrated current limiting and thermal shutdown features, the line drivers protect against shorts to assure highly-reliable operation in harsh environments for industrial encoder and sensor interfaces, industrial programmable logic controllers and servo drive applications.
The new Avago line drivers are designed to meet industrial standards for encoder applications. They offer a robust operating temperature range from -55° to 125°C for the AEIC-7272 and AEIC-7273 devices and -40° to 125°C for the AEIC-2631 device. They are all available in industrial standard line driver SOIC packaging. Offering high-impedance buffered inputs with hysteresis, the line drivers provide strong noise margin even in noisy industrial control environments. Avago is exhibiting the new line drivers along with its portfolio of motion control and isolation solutions for motor applications, at the MotorTech Japan 2011 trade show in East Hall 1 booth number 1D-103 from July 20-22.
The AEIC-2631 device operates in a wide supply voltage range of 4.75V to 30V and features Tri-State outputs. The AEIC-7272 device features Tri-State outputs and the AEIC-7273 device features NPN Open-Collector outputs, and each operates from 3.5V to 30V. The line drivers’ thermal shutdown feature is accomplished by monitoring junction temperature and comparing this to a band gap reference on-chip.
Other features are:
Operation to 800 KHz
CMOS and TTL Compatible Inputs
Separate logic bias and driver supply pins
Optional single supply operation for moderate power
High Impedance Buf ered Inputs with hysteresis
80 mA peak SINK/SOURCE current
Lead-free, 16-pin SOIC package
The Avago AEIC-7272, AEIC-7273 and AEIC-2631 line drivers are priced starting at $2.00 each in 9600 piece quantities. Samples and production quantities are available now through the Avago direct sales channel and via worldwide distribution partners.
