Working Principle

ACPL-H312-000E optocoupler isolator integrates the control circuitry necessary for bidirectional communication with a power MOSFET switch. The device has an input stage with a nominal voltage of 5V DC. An UV-visible (UVA/UVB/VLC) LED is used to convert the electrical signal into light energy and an optically isolated photo-transistor is used to detect the light energy and produce an electrical output. This electrical signal is then amplified by the integrated switch driver and applied to the power MOSFET switch.

The device is designed to ensure that the electrical signals are isolated from each other, preventing electrical noise from one device from affecting the functioning of the other devices. The isolated power rail is also designed to ensure minimal input to output current leakage and ensure high voltage insulation between the two isolated rails.

The optocoupler isolator also offers protection features such as over-current, under-voltage lockout, and fault detection for the highest safety and reliability.

Conclusion

ACPL-H312-000E optocoupler isolator is an ideal choice for high-speed, industrial applications including robotics, motor drives, factory automation, and other sectors that require noise-free, high-speed, or high-efficiency data transmission. The device has an input stage with a nominal voltage of 5V DC and offers protection features such as over-current, under-voltage lockout, and fault detection for the highest safety and reliability.
