The TLP5752 is a ultra-compact 2-channel optically coupled isolator with built-in power MOSFET designed for high speed signal isolation applications. It contains an LED on the input side and a MOSFET on the output side, which provides an electrically isolated interface between two circuits. Due to its small package size, the TLP5752 can be used in numerous applications, especially those requiring more information to be passed through a single unit. Additionally, it has excellent temperature stability and low power consumption.

Applications of the TLP5752

The TLP5752 finds applications in many industries, but its primary use is as a gate driver. It can be used to drive power MOSFETs or IGBTs in high speed switching applications. It can also be used as a high voltage isolator and a control signal converter. Additionally, it can be used to build small systems such as frequency converters and motor drives. It can be used in motor control, automotive, and industrial fieldbus applications, as well as renewable energy, solar, and wind power systems.

Features of the TLP5752

The TLP5752 has many features that make it an ideal choice for isolator and gate driver applications. It is compact and has a low power consumption of only 2mW per channel. It has a low voltage supply of 5.5V and can achieve a blocking voltage up to 5kVrms. It also has a fast response time of 2ns and a wide temperature range of -40°C to +125°C. Additionally, it has a typical isolation voltage of 5kVrms, high common mode transient immunity of 40kV/μs, and ESD protection of up to 8kV HBM.

Working Principle of the TLP5752

The working principle of the TLP5752 is quite simple. It consists of an LED and a MOSFET that are placed in a package with a wall of insulation between them. The LED is connected to the input side of the circuit and emits light when a voltage is applied to it. The light is then received by the MOSFET, which is connected to the output side of the circuit, and results in a current being passed through the output. This current turns on the power MOSFET or IGBT, thus providing a high speed signal isolation between the two circuits.

Conclusion

The TLP5752 is a highly versatile isolator and gate driver that can be used in a wide variety of applications. It offers excellent temperature stability and low power consumption, as well as a fast response time and high common mode transient immunity. Additionally, it has a wide temperature range and a very high ESD protection rating. All of these features make it ideal for isolator and gate driver applications in many industries, such as the automotive, motor control, industrial fieldbus, and renewable energy industries.
