Industry-leading combination of galvanic isolation and small package provide high level of protection in industrial applications
DALLAS, Sept. 30, 2013 /PRNewswire/ -- Texas Instruments (TI) (NASDAQ: TXN) today introduced the industry's first family of digital isolation devices to offer the highest isolation rating, at 2.5 kVrms, in a small, 5- by 6-mm QSOP package. The ISO71xx family is 50-percent smaller than traditional SOIC isolation devices and provides an isolation rating 2.5 times better than competitive devices in the same package. Reducing board space without compromising protection from lower isolation ratings or EFT surges is increasingly important in industrial automation applications, such as programmable logic controllers (PLCs) and sensors, and Fieldbus applications, such as DeviceNet, CAN and RS-485. The low-power ISO71xx family of isolation devices meets these demands by offering up to 2.5 times higher common-mode transient immunity and 30-percent better maximum working voltage, versus similar devices. For more information and to order samples, visit www.ti.com/iso7131-pr.
The family includes six triple and quad devices based on integrated silicon dioxide capacitors and provides both resistance to electromagnetic interference (EMI) and lower EMI radiance to provide increased reliability in harsh environments. To further enhance performance, the devices incorporate a glitch filter to smooth operation at lower frequencies. And with a power rating of approximately 1 mA per channel, the new isolation devices enable low power in these environments.
Key features and benefits of the ISO71xx devices
By combining the ISO71xx family with TI's wide portfolio of gate driver ICs, such as the UCC27531, UCC27517 or UCC27211, it is possible for designers to build compact, high-speed, industrial automation systems and offline, isolated switch-mode power supplies where there is need for the PWM control signal to cross the isolation barrier from one side and drive power semiconductor switches on the other side with short propagation delays.
Tools and support
The low-power digital isolation evaluation module is available to evaluate the isolator performance and parameter using the ISO71xx family. It can be ordered today for US$79.
Support is available on the Industrial Interface Forum in the TI E2E™ Community, where engineers can ask questions and get answers from TI experts.
Availability, packaging and pricing
The triple ISO7131CC and quad ISO7140FCC, ISO7140CC, ISO7141FCC, ISO7141CC and ISO7142CC devices are available in 16-pin, 5- by 6-mm QSOP packages. Suggested retail pricing in 1,000-unit quantities starts at US$1.60.
