Texas Instruments Korea (President Kent Jeon, www.ti.com/ww/kr ) Oct. 11, 2012 – Texas Instruments (TI) (NASDAQ: TXN) today introduced the TPS65831-Q1 multi-rail safety power management IC (PMIC) and the DRV3201-Q1 safety motor driver for use with the Hercules™ TMS570 ARM® Cortex™-R4 safety microcontroller. The Hercules TMS570 safety microcontroller, TI’s first functional safety PMIC and the industry’s first functional safety motor driver combine to form a “safety motor control chipset.” This configuration maximizes fault detection and mitigation while minimizing software overhead. The new motor control safety chipset also includes the SafeTI-26262 and SafeTI-61508 design packages, enabling customers to easily achieve ISO 26262 and IEC 61508 certification and accelerate time to market when designing safety-critical transportation and automotive motor control applications.
This microcontroller is ideal for new advanced driver assistance systems, electric power steering, hybrid and electric vehicles, rail propulsion control, aircraft anti-skid control, and off-road vehicles. The latest Hercules TMS570 safety microcontroller expands the product line to 36, allowing customers to conveniently select the product best suited to their specific application needs. The new Hercules TMS570LS12x/11x floating-point safety microcontrollers offer expanded motor control capabilities along with additional memory and performance configurations, while the Hercules TMS570LS04x/03x safety microcontrollers provide a low-cost entry-level solution in a small package with integrated motor control interface. Compatible PMICs for these microcontrollers integrate multiple power supplies and safety functions into a single device, reducing design time and saving board space. The motor drivers also integrate a functional safety architecture for protection and monitoring, and are the industry's first to offer start/stop functionality.
Key Features and Benefits of the Hercules TMS570 Safety Microcontroller
• Expanded memory options and improved performance: Extended performance and memory options, including 80MHz to 180MHz lockstep ARM Cortex-R4 cores and 256KB, 384KB, 1MB, and 1.25MB flash, provide designers with greater choice and scalability for multi-function safety products.
• Achieves ISO 26262 and IEC 61508 certification: Designed to comply with industrial safety standards at the component level, making it easy to achieve ISO 26262 and IEC 61508 certification in system design.
• Hardware safety features offering a wide range of performance: high level of online diagnostics with lockstep core, memory protection for CPU and bus master, Error Correction Code (ECC) for Flash and Single-bit Error Correction and Double-bit Error Detection (SECDED) for RAM, CPU and RAM built-in self-test (BIST) for potential fault detection, intelligent error signaling module for taking action in response to safety errors, parity for peripheral RAM, redundant analog-to-digital converters (ADCs) and timers, continuous voltage and clock monitoring, etc.
• Integrated motor control: On-chip integration of motor control functions, including enhanced pulse width modulation (PWM), sensor acquisition, and quadrature encoder interface, reduces external component count, and a 32-channel timer coprocessor acts as a redundant motor control channel, enabling PWM integrity checks of the motor control loop.
• Pin compatibility: Pin-compatible with the Hercules TMS570LS31x/21x safety microcontrollers released last year (Hercules TM(For S570LS12x/11x floating-point safety microcontrollers only) Mass production is scheduled for October 31, 2012.
• Integrated on-chip FlexRay™, CAN, Ethernet, and LIN connectivity: Integrated on-chip FlexRay™, CAN, Ethernet, and LIN connectivity provides support for standard automotive networks and a variety of options for data acquisition.
Key features and benefits of TI's first functional safety PMIC, the TPS65381-Q1
• Multiple power supply rails in a single device: An asynchronous buck switch power supply converter with internal FETs converts the input battery voltage to a 6V pre-regulator output, which powers the other regulators. Two linear regulators with internal FETs supply power to the Controller Area Network (CAN) and microcontroller input/output (I/O), and one linear regulator controller powers the microcontroller core. This integration of multiple power rails reduces design time and saves valuable board space.
• Additional sensor power supply: Provides short-to-ground and short-to-battery protection, allowing power to be supplied to sensors outside the Electronic Control Unit (ECU).
• Integrated functional safety architecture with various functions: question-and-response watchdog, MCU error signal monitor, clock monitoring for internal oscillator, self-check for clock monitor, cyclic redundancy check (CRC) for non-volatile memory, reset circuit for microcontroller, etc. In addition, BIST function can monitor device function at startup, and dedicated diagnostic function can be used by microcontroller to check PMIC safety function. Integrating these safety features eliminates the need for additional monitoring microcontrollers, saving cost, board space, and software development time.
Key Features and Benefits of the DRV3201-Q1, the Industry's First Functional Safety Motor Driver
• Bridge driver for automotive 3-phase brushless DC motors: Provides six dedicated drivers capable of driving steady-state N-channel MOSFET transistors with charge capacitances up to 250nC, with programmable driver source/sink current for convenient output slope adjustment.
