These devices are known for their high voltage, high speed, and wide operating temperature range that cover -40°C to +85°C. This device also provides 5kV/µs of electrical transient immunity, and a 5KV of creepage and clearance at the smallest isolated lead spacing available.

This device also has a range of supply currents from 1.6mA to 5mA, and an excellent package design for easy installation. It has a low capacitance with TTL/CMOS compatible logic output, and a typical rise/fall time of 2.5μs/10μs. The LED performance is controlled for maximum consistency and guaranteed minimum magnitude of off-state voltage.

Applications

The HCPL-1931#200 can be used in a variety of applications due to its high voltage, frequency output, and wide operating temperature range. These applications include motor control, power management, digital displays, and line-frequency power isolation. This device is also used in for high-speed logic interface, serial-data transmission, medical equipment, factory automation, and automotive applications.

Working Principle

The HCPL-1931#200 is based on the principle of optoisolation. When an electric current flows through an LED, it emits light. The light then passes through an opto-isolator, an optical device with a light sensitive surface. This sensitive surface then converts the light into an electrical signal, and sends it to the output side of the device.

The device then triggers the output, resulting in the logic output from the device. The logic output is either HIGH or LOW, depending on the current, voltage, frequency allowed by the device. The HIGH/LOW output is used for applications with serial data transmission, processors, logic controls, and motor controlling.

Conclusion

The HCPL-1931#200 is a High-Voltage Gate Drive Optocoupler from the optoisolator with logic output category. This device has a wide operating temperature range, current rate, and frequency output. It is suitable for motor controlling, power management, digital displays, and line-frequency power isolation. The working principle of this device is based on the principle of optoisolation.
