Reinforced isolator with integrated power offers industry's highest efficiency, lowest emissions
Texas Instruments introduced a new single-chip reinforced isolator with integrated power that offers 80 percent higher efficiency than existing integrated devices. With the industry's most efficient power transfer, lowest radiated emissions and highest immunity this new reinforced isolator supports reliable operation of industrial systems, including factory automation, grid infrastructure, motor control, isolated power supplies, and test and measurement equipment.
Compared to discrete solutions, the ISOW7841 integrates both isolated data and power, enabling a smaller bill of materials (BOM) and reduced board space, as well as helping with easier and faster system certification. For more information, see www.ti.com/isow-pr.
Key features and benefits of the ISOW7841
- Eighty percent higher efficiency: With the industry's lowest power consumption, the ISOW7841 reduces device operating temperature by up to 40 degrees C, enabling higher power delivery, higher channel count and longer system lifetime than other integrated solutions.
- Single-chip reinforced isolated power and data up to 100 Mbps: Combining reinforced isolation and DC/DC conversion in a single package minimizes board space and cost for easier multichannel system design. A working voltage of 1 kVrms helps provide improved system reliability and lifetime. The ISOW7841 supports an input voltage range of 3V to 5.5V, while delivering an industry best 0.65W of output power.
- More than 10-dB lower radiated emissions: The ISOW7841 improves system signal integrity by minimizing system noise and providing robust electromagnetic compatibility to meet International Electrotechnical Commission (IEC) 61000-4-x standards for electrostatic discharge and electrical fast transient events. Additionally, the reinforced isolator offers the highest level of immunity available in the market today reducing the effect of noise and high-voltage events on the industrial equipment.
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.
