Reinforced digital isolator

15 August 2018 Analogue, Mixed Signal, LSI

To better protect industrial systems from the dangers of high-voltage signals, equipment designers can employ the new robust and reliable MAX22445 5 kVRMS four-channel reinforced digital isolator from Maxim Integrated Products. Delivering high throughput at low power consumption versus competing solutions, the device provides reliable communication across the isolation barrier to ensure safe operation of compact industrial, medical and other equipment.

In high-voltage equipment, digital isolators provide signal isolation and level-shifting for proper operation of many circuits, while also protecting users from dangers such as electric shock. Yet, not all of these isolators are alike as many consume a large amount of power, generate significant heat and introduce large propagation delays, limiting system reliability and throughput.

Claiming to overcome the shortcomings of other digital isolators, the MAX22445 delivers reinforced, dual insulation barrier isolation for fast digital signals. The IC, which mitigates the dangers of high-voltage power, transfers signals of up to 200 Mbps with little power consumed. It is available in a 16-pin wide-body SOIC package with 8 mm of creepage and clearance.

The chip features 0,41 mA per channel current consumption and 0,74 mW power consumption at 1 Mbps with VDD at 1,8 V. Maximum propagation delay of 10,5 ns and maximum data rate of 200 Mbps enable fast and accurate data acquisition and high-speed interfaces with wide timing margins.
