TI enables more efficient motor design with faster, more accurate current-sense amplifier
Texas Instruments » INA240
Industry-leading current-shunt monitor improves efficiency and accuracy for motor and solenoid control applications
Texas Instruments (TI) 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.
Key features and benefits
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.
