Texas Instruments promises users of its new motor control safety chipset, comprising twelve Hercules TMS570 ARM Cortex-R4 safety microcontrollers along with the TPS65831-Q1 multi-rail safety power management IC (PMIC) and the DRV3201-Q1 safety motor driver, shorter time to market for safety-critical motor control applications. These devices maximize failure detection and mitigation while minimizing software overhead. The new chipset adheres to the SafeTI-26262 and SafeTI-61508 design packages, helping customers more easily achieve ISO 26262 and IEC 61508 certification.
Designed for advanced driver assistance systems, electric power steering, hybrid and electric vehicles, rail propulsion control, aviation anti-skid control, off-road vehicles and more, the new Hercules TMS570 safety microcontrollers support 36 configurations to meet application-specific needs. The Hercules TMS570LS12x/11x floating-point safety microcontrollers provide additional memory and performance configurations with expanded motor control capabilities, while the Hercules TMS570LS04x/03x safety microcontrollers provide a smaller package, lower cost, entry-level solution with integrated motor control interfaces. The compatible PMIC combines multiple power supplies and safety features in a single device to reduce design time and board space.
