World's first combination protection-and-termination IC enables
system designers to increase performance, reduce power, simplify
design GENEVA, Feb. 12 /PRNewswire-FirstCall/ -- STMicroelectronics
(NYSE:STM), a world leader in protection ICs, has announced the
world's first device combining field signal-termination and
protection functions, enabling designers of industrial control and
building-automation equipment to increase system performance and
EMI robustness while simultaneously cutting power consumption,
size, and heat dissipation. Digital automation in factories and
buildings helps companies collect detailed information for
manufacturing process improvements. The market for control and
processing equipment is expected to exceed $71.6bn globally in
2010*. The equipment is becoming more sophisticated as designers
add extra digital signal channels to increase system capabilities
and precision. Traditionally, this also increases size and power
consumption of functional blocks, such as line transceivers and
optical isolators, which require extra components to handle the
additional channels. Optical isolation usually requires further
protection, for equipment and users, against effects such as power
surges or electrostatic discharge (ESD). ST's SCLT3-8BT8 integrated
protection and signal-termination device allows designers to
increase the number of channels in new equipment designs without
adding large numbers of extra components. Using conventional
terminations, one optical transistor is required per data channel.
The SCLT3-8BT8 combines eight data channels into a single serial
output, allowing the number of optical transistors and associated
components to be reduced significantly. This approach can save in
excess of 50% of pc-board area and about 30% of power consumption,
compared to existing alternatives. The effective power consumption
is less than 78mW per input, which saves energy and reduces heat
generated by the isolator. This benefit is particularly valuable
for sealed control units, which are required in applications such
as food-processing and chemical industries. With input
characteristics meeting the international standard IEC61131-2 for
programmable controllers, the device can be used in equipment for a
wide range of applications and environments. The SCLT3-8BT8's
built-in protection features meet the IEC61000-4 standards for
electrical transients up to +/-4kV, voltage surges up to +/-1kV,
and ESD up to +/-15kV air discharge. The device provides an
industry-standard SPI communication interface, enabling direct
connection to other components in the system such as ST's VNI8200
high-side driver or an STM32 or STM8 microcontroller. Samples of
the SCLT3-8BT8 are now in stock, and budgetary pricing is $3.20 for
orders over 1000 units. About STMicroelectronics STMicroelectronics
