TI enables more efficient motor design with faster, more accurate current-sense amplifier

Industry-leading current-shunt monitor improves efficiency and accuracy for motor and solenoid control applications

DALLAS, Nov. 8, 2016 — (PRNewswire) —  Texas Instruments (TI) (NASDAQ: TXN) today introduced a new current-sense amplifier for in-line motor phase current measurement that improves overall motor efficiency, compared to existing current-sense amplifiers. The INA240 offers enhanced pulse-width modulation (PWM) rejection for systems running at up to 80 V to support a variety of applications such as motor control, solenoid control and power delivery systems. For more information about the new current-sense amplifier or to order samples, see www.ti.com/INA240-pr.

Key features and benefits

To see the new current-sense amplifier in a live Smart Factory Industry 4.0 demonstration and learn about other ways TI is engineering industrial innovation, visit Booth 219 in Hall A4 at electronica, Nov. 8-11, 2016. The INA240 will also be on display at the SPS IPC Drives exhibition in Booth 6-441 starting Nov. 22.

Tools and support to jump-start design
Short, use-case technical notes called TI TechNotes offer engineers implementation techniques related to low-drift in-line motor current phase measurement and current monitoring for overcurrent protection.

Support is available in the TI E2E™ Community Current Sensing forum, where engineers can search for solutions, get help, share knowledge, and solve problems with fellow engineers and TI experts. As with TI's entire current-sensing portfolio, designers have access to a full suite of support resources, including a complete library of TI Designs reference designs, evaluation modules (EVMs), online training series and SPICE models.

Package, availability and pricing
The 8-pin INA240 is available now in a 3-mm-by-4.4-mm thin-shrink small outline package (TSSOP) from the TI store and authorized distributors. Pricing is US$0.99 in 1,000-unit quantities. An evaluation module (EVM) is available now in the TI store for US$25.

The INA240 is the latest addition to TI's growing portfolio of innovative current-sense amplifiers that offers a leading combination of power, efficiency and accuracy. Explore TI's entire current-sense amplifier portfolio.
