Optoisolators are used in a range of applications, including medical, automotive, entertainment, and consumer goods. The TLP626(BV,F) is a photovoltaic output transistor optoisolator, specifically designed for industrial and consumer applications.

The TLP626(BV,F) is designed to provide an optically isolated, bidirectional DC voltage converter between high and low voltages, making it suitable in applications such as motor control and general power line isolation. It is constructed with a customized optical format, and also features a shielded case (IP6K9K).

The optoisolator’s construction consists of an infrared LED emitter encased in a 6-pin SMT package and a phototransistor receiver housed in a 6-lead flatcan package. The optoisolator is sensitive to infrared signals from the LED, and the output of the phototransistor subjects the signal at the input to a voltage conversion. This conversion occurs at a 10-30 kHz frequency, and allows the information to be transferred accurately and reliably over the isolated interface.

The input and output pins of the optoisolator are short-circuit and overload protected, as well as open-drain circuits that are both polarity and maximum voltage (500V) protected. This ensures that it can be used in small and large electronic circuits, and ease of testing as required.

In terms of performance, the TLP626(BV,F) optoisolator has a guaranteed delay time of 40µs, an output resistance of 40kΩ, and an isolation voltage of 4,000Vrms. The voltage transfer ratio of the device can range from 14.2V to 30V, and the minimum sensitivity rating of the LED is 0.2mA. Additionally, it operates over a wide ambient temperature range of -40°C to 85°C, making it suitable for most industrial and consumer applications.

The TLP626(BV,F) optoisolator is typically used in motor control, power line isolation, high voltage pulse resetting, and motor speed control applications. In motor control, the optoisolator can detect changes in direction, as well as monitor the temperature of the motor and calculate the current direction of the motor.

In power line applications, it is used to provide protection against electrical surge and provide galvanic isolation between the power line and the logic circuit. It can also be used in circuit resetting applications, where it can detect a positive voltage pulse and convert it to a logic level for use in the circuit.

Finally, it can be used in motor speed control applications, thanks to its wide operating voltage range and sensing capability. The optoisolator can detect the current speed of the motor and send the signal to the logic circuit, allowing the speed to be controlled accurately and precisely.

The TLP626(BV,F) optoisolator is a reliable and versatile photovoltaic output transistor optoisolator that provides protection against electrical surge and galvanic isolation between the power line and the logic circuit. Its performance meets or exceeds the requirements of many industrial and consumer applications, making it an ideal choice for motor control, power line isolation, high voltage pulse resetting, and motor speed control.
