Optoisolators utilize light to transfer electrical signals between two isolated areas, blocking out electrical noise while still passing the signal. The SL55013SD is an isolated switching interface that provides galvanic isolation between power supply and load circuits. This specially designed optoisolator features a high-speed switching response and a wide operating voltage range. The product is capable of selectively protecting a wide variety of industrial and consumer electronic devices from harsh electrical environments.

The SL55013SD is a photovoltaic output optoisolator. When current passes through the internal LED, it emits light which is detected by the phototransistor inside the device, generating two active and a static output signals. The dynamic output (active) transistors conduct their output signals at predetermined thresholds, while reverse clamping diodes at the output protect from overloads resulting from excessive voltage. The logic gate(s) forming the sensor circuit is complemented by a diode for Schmitt-trigger behavior.

The SL55013SD is available with supply voltage ratings from 1.8V to 20V, with an operating frequency range up to 40kHz. Its isolation voltage rating is 5kV DC, making it ideal for use in industrial applications, such as industrial motors, pumps, and HVAC equipment. Its small package size allows it to be easily integrated into existing systems.

The SL55013SD provides high-speed switching to reduce power losses, allowing for improved efficiency in power applications. Its low saturation voltage and fast switching time make it more resistant to interference and thermal shock. As a result, the device can be used in applications where high efficiency and minimal noise are required.

An example of an application for the SL55013SD is in a motor controller. The optoisolator can be used to control the switching of the motor’s power supply to its various speed settings. The controller can sense the inputs from the user, detect the appropriate switch positions, and generate the necessary signals to control the motor. Its high-speed switching and wide operating voltage range make it an ideal solution for the task at hand.

In summary, the SL55013SD is a photovoltaic output optoisolator designed for use in a wide variety of industrial and consumer electronic applications. Its high-speed switching and wide voltage range allow for improved efficiency in power applications. It is especially well suited for motor controllers and other applications which require high efficiency and minimal noise.
