Optoisolators play an important role in isolating signals between electronic circuits. In particular, they provide effective isolation between low current gate inputs and high current sources. The HCPL2631SDM logic output opto-isolator is a reliable and robust device ideal for voltage isolation between gate inputs and high supply voltages. It is also suitable for circuit protection and signal isolation.

The HCPL2631SDM’s main performance characteristics include input-output insulation of 15 kV/1 minute at a distance of 10 mm in isolation voltage. This isolator complies with the UL 1577 double module, with 830 VDC isolation voltage and rated current of 0.5 A. It is suitable for operating temperatures from -40 to +100 °C, and provides a noise immunity capability of 22 kV/μs. It is also available with a wide range of input and output voltage ratings, from 1.5 V to 30 V with 6 opto and NPN outputs.

The HCPL2631SDM optoisolator has an industry-standard footprint with a DIP-8 package that is easy to mount on printed circuit boards. It also features high common mode transient immunity, fast rise and fall times, high signal frequency, and full turn-on of the output LED in under 10 ns. It also has a narrow input-output voltage range, which improves isolation performance.

The HCPL2631SDM is suitable for a number of applications, including battery powered systems, LED configuration, and communication systems. It can also be used in open or enclosed automation systems. It is typically employed as a device for optically isolating low-level control signals from higher voltage/current sources. It is also used as a signal isolator for communications with other digital modules and instrumentation.

The HCPL2631SDM utilizes an LED, light sensor, and amplifier to isolate signals. The LED emits light when a low voltage input is applied to it. The light is then detected by the opto-sensor. The signal is then amplified and passed through an isolation barrier before being fed to the output. This arrangement allows the high voltage on the receiving side to remain isolated from the low voltage control voltage on the sending side.

In summary, the HCPL2631SDM is a reliable and robust logic output optoisolator suitable for voltage isolation between gate inputs and high supply voltages. It is capable of providing input-output insulation of 15 kV/1 minute at a distance of 10 mm in isolation voltage. These features make it ideal for applications such as battery powered systems, LED configuration, and communication systems.
