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.
With low-power consumption, the ISOW7841 reduces device operating temperature by up to 40° C, enabling higher power delivery, higher channel count and longer system lifetime than other integrated solutions. 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 3 V to 5.5 V, while delivering t 0.65 W of output power.
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. In addition, the reinforced isolator offers one of the highest levels of immunity available, 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. The part comes in a 16-pin small outline integrated circuit (SOIC) wide-body package. This device is available in both fail-safe low and fail-safe high configurations.
