Texas Instruments has expanded its offerings for safety-critical automotive and transportation motor control applications.
The company introduced twelve Hercules TMS570 ARM Cortex-R4 safety microcontrollers, a complementary TPS65831-Q1 multi-rail safety power management IC and DRV3201-Q1 safety motor driver.
The combination forms what TI labels as a “safety motor control chip set” that maximizes failure detection and mitigation while minimizing software overhead, according to TI.

The new motor control safety chip set adheres to the SafeTI-26262 and SafeTI-61508 design packages, which lets designers more easily achieve ISO 26262 and IEC 61508 certifications for transportation motor control applications.
The new Hercules TMS570 microcontrollers expand the product line to include 36 configurations. They expand the range of performance and memory options, from 80 MHz to 180 MHz lockstep ARM Cortex-R4 cores and 256KB, 384KB, 1MB and 1.25MB Flash.
TI’s first functional safety PMIC, the TPS65381-Q1 includes multiple power supply rails in a single device, including an asynchronous buck switch-mode power-supply converter with internal FET converts the input battery voltage to 6V pre-regulator output, which supplies other regulators.
The DRV3201-Q1 motor driver is dedicated to automotive three-phase brushless DC motors, providing six dedicated drivers for normal level N-Channel MOSFET transistors up to 250nC charge.
Hercules TMS570 microcontrollers range from $5 to $22 in 1,000-unit quantities and samples are immediately available for order. A variety of free software and tools ranging from $79 to $599 are available today.
