Optoisolators are components that provide the reliable electrical isolation of two circuits. The HCPL4503TSR2VM is a particular type of optoisolator known as a transistor, photovoltaic output. This component is designed for use with transistor-based logic circuits, and it is a compact, integrated, optically isolated interface used in variety of applications where a reliable, high-performance isolation barrier is necessary. It is suitable for TTL and CMOS (including LVDS) signals and has an operational transistor output current of 25mA.

Application Field

The HCPL4503TSR2VM optoisolator is used to provide reliable electrical isolation between two circuits, such as between the logic circuitry and the load. It is a compact, cost effective way to protect components from transients and noise, while also allowing for full data transfer between the two circuits. The HCPL4503TSR2VM is designed to work in a wide variety of applications, including high temperature industrial and automotive electronics, consumer electronics, telecommunications, data acquisition, motor control and more.

Working Principle

The HCPL4503TSR2VM works by using light to transmit a signal between two truly isolated circuits. It consists of an LED light source on one side, and a photodiode on the other. When a voltage is applied to the LED, it causes a light signal to be emitted, which is received by the photodiode on the other side. This signal is then converted into a voltage that can be used in the logic or load circuit.

The HCPL4503TSR2VM is also designed to be very efficient. It can isolate a signal up to 10KV at normal temperatures, and up to 5KV at high temperatures. This means it can provide a reliable isolation barrier, even in very harsh environments.

The HCPL4503TSR2VM is also designed to be very compact. It has an overall size of 10x7.5mm, making it a cost effective solution for isolating signals in tight spaces. This small size also means that it can be used in a wide variety of applications, from high temperature automotive electronics to consumer electronics.

Conclusion

The HCPL4503TSR2VM is a compact, cost effective optoisolator designed for use with transistor-based logic circuits. It can provide reliable electrical isolation between two circuits, and it is designed to work in a wide variety of applications. The HCPL4503TSR2VM can isolate a signal up to 10KV at normal temperatures, and up to 5KV at high temperatures. It also has a small size of 10x7.5mm, making it an ideal solution for isolating signals in tight spaces.
