TI introduces motor driver family with integrated power management and CAN interface for use in automotive functional safety applications
DALLAS, July 11, 2013 /PRNewswire/ -- Texas Instruments (TI) (NASDAQ: TXN) today expanded the industry's first automotive motor driver family intended to help TI customers design automotive applications to meet the functional safety requirements of ISO 26262. With three new devices added today, the DRV32xx-Q1 family now comprises four 3-phase, brushless, pre-FET motor drivers equipped with built-in diagnostic capabilities. The DRV3202-Q1 offers automotive system designers integrated power management and CAN interface to help reduce board space and design complexity in their safety-critical applications. The DRV3203-Q1 and DRV3204-Q1 help TI customers design safety-critical applications to meet ASIL-B, while the DRV3201-Q1, previously introduced in October, 2012 helps TI customers design safety-critical applications to meet ASIL-D requirements.
The three new motor drivers added to the family provide designers with highly reliable and space-saving options intended to help them address the challenges of space constraints and harsh conditions such as high-temperature, low-voltage start-stop and cold crank situations. Applications in which these devices may be used include power steering, hybrid electric vehicles/electric vehicles (HEV/EV), power train, oil pump, water pump and electric braking systems. For more information or to order samples, visit http://www.ti.com/automotordriver-pr.
Key features and benefits of the DRV32xx-Q1 family:
-- Optimized component count and board space for cost- and space-sensitive
applications: The DRV3202-Q1 integrates a voltage regulator and CAN
interface to reduce component count and minimize system cost and board
space.
-- Built-in diagnostics: The DRV32xx-Q1 family integrates hard-wired
diagnostic circuits including a pre-FET driver short, over/under voltage
and over temperature. The system's microcontroller can quickly
communicate with the DRV32xx-Q1 family and monitor internal status
through serial peripheral interface (SPI).
-- Devices help TI customers design applications to meet the functional
safety requirements of ISO 26262: The DRV3201-Q1 can help TI customers
design critical-safety applications, such as electric power steering and
electric braking systems, to meet ASIL-D requirements, and the
DRV3204-Q1 and DRV3203-Q1 can help customers design safety applications,
such as oil pump and water pump, to meet ASIL-B requirements.
-- Design simplicity for start-stop and cold crank applications: With an
integrated boost regulator, the DRV3201-Q1 eliminates the need for a
large capacitor to hold battery voltage. With an integrated low drop-out
linear regulator controller (LDO) and an external FET, the DRV3203-Q1
and DRV3204-Q1 also eliminate the need for a large capacitor or external
boost regulator. This integration simplifies design and speeds up
development time.
Highly integrated motor drivers for non-safety critical automotive applications
TI has also expanded its portfolio of DRV8x motor drivers to include new devices for automotive applications that span a complete range of motors including brushed DC (BDC), stepper, and brushless DC (BLDC). The highly integrated DRV8801-Q1, DRV8823-Q1, DRV8832-Q1 and DRV8301-Q1 can reduce board space by as much as 60% compared to the competition enabling smaller, more cost effective designs. All four devices support an operating ambient temperature range of -40 to 125C, targeting non-safety critical automotive applications such as retractable navigation screens; adjustable side mirrors; adaptive front lighting; fuel pumps; and seat, door, and window control. The new devices include the following:
-- DRV8801-Q1 brushed DC motor driver, featuring 8-V to 38-V operating
range and up to 2.8-A peak output.
-- DRV8823-Q1 quad brushed, dual stepper motor driver, featuring 8-V to
32-V operating range and up to 1.5-A peak output current.
-- DRV8832-Q1 brushed DC motor driver, featuring 2.75-V to 6.8-V operating
range and up to 1-A peak output current.
-- DRV8301-Q1 3-phase brushless motor pre-driver, featuring 6-V to 60-V
operating range and integrating a gate drive up to 1.7-A, 1.5-A
step-down voltage regulator, and dual low side current sense amplifiers.
Tools and support:
Simulation models and evaluation modules (EVMs) are available for the DRV3203-Q1 and DRV3204-Q1 at http://www.ti.com/automotordriver-pr.
Evaluation modules (EVMs) are also available today for the DRV8801-Q1, DRV8823-Q1, DRV8832-Q1 and DRV8301-Q1.
