Two New ARM® Core-Based MCUs Are Targeted To Be ISO 26262 Compliant; Provide High-Performance Power Steering and Motor Drive Control for Hybrid/Electric Cars

Toshiba America Electronic Components, Inc. (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, today announced two new 32-bit ARM® Cortex®-M3 core-based microcontroller (MCU) devices designed for use in automotive electronic control units, the electronic sub-systems within a car that control functions like power steering or the drive motor in hybrid and electric cars. Additionally, the TMPM350FDTFG and TMPM354F10TFG MCUs are both manufactured in compliance with the latest draft of the automotive industry’s upcoming ISO 26262 safety standard.

"Once the ISO 26262 safety standard is published next year, the automotive industry will have a standardized approach for implementing fail-safe functionality in the MCUs used in the electronic control units of vital automotive systems," said Andrew Burt, vice president, Analog and Imaging Business Unit, System LSI Group, TAEC. "The market for MCUs that support the ISO 26262 standard is expected to grow rapidly and with the launch of these two new MCUs, Toshiba is well positioned to meet demand from automotive OEMs."

The TMPM350FDTFG MCU incorporates Toshiba's original programmable motor driver, an excitation signal1 output circuit for resolvers and A/D converters. These features make the MCU a compelling solution for use in power steering control units, where enhancement of the external signal input from the motor and detailed setting of the output signal can deliver more precise steering to a driver.

The TMPM354F10TFG MCU is primarily designed to control drive motors in electric or hybrid cars. The device incorporates an on-chip resolver digital converter that converts signals from the motor resolver to digital data, yielding a smaller design footprint. While previous products used in drive motor control units only worked with rotation position sensors using excitation signals, the more versatile TMPM354F10TFG device also supports resolvers that do not use excitation signals by correcting sensor input signals. Furthermore, the MCU reduces CPU operation cycles by more than 50 percent since it performs a motor's basic vector control operations in hardware; previous solutions could only support this function in software.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
