Innovation from STMicroelectronics Boosts Safety, Reliability and Efficiency of Industrial-Automation Systems
(Thomson Reuters ONE) -
World's first galvanic-isolation high-side switch with pure RF communication
saves board space and power, enhances noise immunity
Geneva, November 21, 2013 - STMicroelectronics (NYSE: STM), a global
semiconductor leader serving customers across the spectrum of electronics
applications, is launching its new ISO8200B, an innovative isolated power switch
that enables smaller, more robust and energy-efficient controllers for
industrial automation equipment.
A wide variety of industrial-automation equipment, as well as general
programmable logic controller (PLC) applications, will benefit from the enhanced
space savings, user safety, noise immunity, reliability and energy efficiency
offered by this new device.
Industrial switches require physical separation, or galvanic isolation, to
protect the logic-controlled circuitry from disturbances on the power side, and
to ensure user safety. Conventional, discrete optical isolators (opto-couplers)
used for this purpose occupy additional pc-board space and are subject to aging
and temperature-related degradation driving up ownership costs.
"The ISO8200B isolated high-side switch is the first integrated device from ST
to combine galvanically isolated power and logic circuitry in the same package,
allowing smaller controllers and lower cost of ownership," said Matteo Lo
Presti, Group Vice President and General Manager, Industrial and Power
Conversion Division, STMicroelectronics. "Moreover, as the industry's first such
device to utilize a pure RF link enabling communication through the isolation
layer, the ISO8200B provides superior noise immunity for ultra-robust and
reliable operation."
Inside the ISO8200B, separate logic and power chips are stacked with the layer
interposer that provides very high isolation. The inputs are connected directly
to a microcontroller or FPGA (Field-Programmable Gate Array), and the device can
drive eight output channels connected to any kind of load connected to ground,
whether inductive, capacitive or resistive. The ISO8200B meets theRF immunity
standard IEC 61000-4-3.
The design of the IC also ensures low quiescent operating current, reducing
power dissipation and saving energy compared to a traditional, opto-coupler
based solution. In addition, the ISO8200B integrated power switch has very low
on-state resistance, which minimizes system energy losses and ensures superior
thermal performance for enhanced reliability.
The ISO8200B integrates circuitry for fast demagnetization of inductive loads
such as motors or heaters, which delivers further space and cost savings. Built-
in protection features guard against over-temperature, short circuit, under-
voltage, over-voltage, loss-of-ground or loss-of-supply voltage. In addition a
fault output allows direct monitoring of correct operation.
The ISO8200B is in production now in the PSO36 package, priced from $3.50 for
orders over 1000 pieces.
