Teridian Introduces First Merchant SOC for Industrial Motor Circuit Protection and Circuit Breaker Applications
Electronic Trip Unit from Teridian Extends the Life of Industrial Automation Systems Via Programmable Trip Threshold and Delay Profiles
Irvine, Calif., October 16, 2006 - Teridian Semiconductor Corp. today reinforced its entrance into the industrial automation and control market with the introduction of the 71M6403 Electronic Trip Unit, the industry's first merchant system-on-chip (SOC) for industrial motor circuit protection and circuit breaker applications. The 71M6403 provides reliable start-up in motor circuit protection applications, preventing damage to the motor and increasing the useful life of the motor. The device can also be used in air, molded case, and insulated circuit breakers in factories, utilities and commercial buildings.
This programmable device can be tuned according to voltage, current, rate of voltage increase and rate of current increase. The 71M6403 is also designed to trip instantaneously on threshold events within less than 7 ms from power on, or can be set to trip on delay, based on user-determined current and voltage profiles.
"New variable-speed, energy-efficient motors have particularly high in-rush currents, and the programmability of our 71M6403 allows such transients to safely clear at start-up, in effect extending the longevity of the equipment itself, and avoiding nuisance tripping or National Electric Code® nonconformance," said Steve McClure, vice president of marketing for Teridian. "As the first merchant SOC provider for these applications, we're once again demonstrating how delivering intelligence and integration to industrial applications - especially as this market transitions to smaller, more full-featured solutions - can greatly reduce development costs for our customers and also create operational and hands-on management savings for the end user."
Utilizing Teridian's patented Single Converter Technology(TM), the 71M6403 incorporates a 22-bit delta-sigma ADC, 7 current sensor inputs, digital temperature compensation, precision voltage reference, 32-bit programmable computation engine, timers, Real Time Clock (RTC), two UARTs and an single cycle execution 8-bit MCU.
Armed with an internal digital di/dt integrator, this programmable device supports either current transformer (CT) or Rogowski-Coils for any or all input channels and provides instantaneous and delayed over current, earth-leakage, ground-fault and arc fault protection functions. Furthermore, the device may be configured to support any number of conventional or custom protection algorithms that fit specific load configurations in the field. The 71M6403 also includes a 5V LCD charge pump as well as 3V LCD support with up to 168 pixels display and up to 22 DIO pins.
The Teridian 71M6403, together with the company's 71M65xx Power Measurement, 71M8100 Measurement Controller, and 78Q2133 Industrial Ethernet product families, provides one of the broadest selections of semiconductor products for today's energy management and industrial automation applications.
