TI Korea (CEO Kent Chon, www.ti.com/ww/kr ) July 17, 2013 – TI (CEO Kent Chon) announced the launch of the industry's first automotive motor driver family that meets ISO 26262 standard functional safety requirements and supports automotive application designs. The DRV32xx-Q1 family, consisting of three new devices, includes four 3-phase brushless pre-FET motor drivers with integrated diagnostic capabilities. The DRV3202-Q1 integrates power management and a CAN interface to save board space and reduce design complexity for safety-centric application designs. The DRV3203-Q1 and DRV3204-Q1 support safety application designs that meet ASIL-B. The DRV3201-Q1, released in October 2012, helps design safety applications that meet ASIL-D requirements.

The latest three types of motor drivers provide a space-saving solution that addresses space constraint challenges and combines excellent stability to withstand harsh conditions, such as high temperatures, low-voltage start-stops, and cold cranking. They are particularly suitable for applications such as power steering, HEV/EVs, powertrains, oil pumps, water pumps, and electric brake systems.

Key Features and Benefits of the DRV32xx-Q1 Product Family
• Optimization of component count and board space for cost and size-sensitive applications: The DRV3202-Q1 integrates a voltage regulator and a CAN interface to reduce component count and minimize system cost and board space.
• Built-in Diagnostic Functions: The DRV32xx-Q1 family incorporates hard-wired diagnostic circuitry to protect against pre-FET driver shorts, overvoltage/undervoltage, and overheating. The system microcontroller communicates rapidly with the DRV32xx-Q1 product and monitors its internal status via the SPI (serial peripheral interface).
• Enables the design of applications that meet ISO 26262 standard functional safety requirements: DRV3201-Q1 supports the design of safety applications that meet ASIL-D requirements, such as electric power steering or electric brake systems, while DRV3204-Q1 and DRV3203-Q1 support the design of safety applications that meet ASIL-B requirements, such as oil pumps or water pumps.
• Simplified design for start-stop and cold crank applications: The DRV3201-Q1 integrates a boost regulator, eliminating the need for large capacitors to maintain battery voltage. The DRV3203-Q1 and DRV3204-Q1 also use an integrated LDO (low dropout) linear regulator controller and an external FET, allowing for simplified design and reduced development time without large capacitors or external boost regulators.

TI's Integrated Motor Drivers for Other Automotive Applications
TI has added new devices to its DRV8x motor driver portfolio, expanding support for automotive applications to include a range of motors such as brushed DC (BDC), stepper, and brushless DC (BLDC). The highly integrated DRV8801-Q1, DRV8823-Q1, DRV8832-Q1, and DRV8301-Q1 devices can save up to 60% of board space compared to competitors, enabling more compact and cost-effective designs. These four types of devices operate in a temperature range of 40°C to 125°C and are also suitable for major automotive applications that are not related to safety, such as foldable navigation screens, adjustable side mirrors, intelligent headlights, fuel pumps, and seat/door/window controls.
