TI: reinforced isolator with integrated power
Texas Instruments introduced a new single-chip reinforced isolator with integrated power that offers 80 percent higher efficiency than existing integrated devices. Compared to discrete solutions, the ISOW7841 integrates both isolated data and power, enabling a smaller bill of materials and reduced board space, as well as helping with easier and faster system certification.
The ISOW7841 reinforced isolator with a three forward/one backward channel configuration is the first device in the ISOW78xx family, with multiple devices expected later in 2017. These new devices join TI’s isolation portfolio that supports the highest isolation ratings, reliability, immunity and performance.
Designers can quickly and easily evaluate the new reinforced isolator with the ISOW7841 evaluation module (ISOW7841EVM), available today for US$49 from the TI store and authorized distributors. Engineers can also jump-start their system design with the integrated signal and power reference designs for isolated RS-485 and RS-232. Additionally, another reference design is available to help integrate reinforced isolation and power in an industrial grid design.
The ISOW7841 reinforced isolator with integrated power is now available through the TI store and authorized distributors in a 16-pin SOIC wide-body package. This device is available in both fail-safe low and fail-safe high configurations.
