MXLSMCGLCE75A Circuit Protection

TVS - Diodes

TVS - Diodes are voltage-controlled devices, typically used in electronic circuits to limit overvoltage transients caused by electrostatic discharge or inductive load switching. The MXLSMCGLCE75A is an integrated circuit that incorporates the functionality of a voltage protection device in a single package. It can replace discrete diodes, transistors, and resistors, making it ideal for applications where space is at a premium.

Application Field

The MXLSMCGLCE75A is ideally suited for overvoltage protection in portable and embedded applications. Its overvoltage protection circuit blocks input voltage up to 900V, while simultaneously permitting an output voltage between 4 to 30V. With its high level of protection, it can be used in computer systems, communication systems, industrial automation systems, and other applications that require a high level of protection from overvoltage transients.

Working Principle

The MXLSMCGLCE75A operates on the principle that a voltage transient will cause a current flow, bar a specific reverse breakdown voltage. When a voltage transient is detected, the device turns on and limits the current flow, preventing voltage spikes from damaging sensitive components in the circuit. The device does not require any voltage suppression devices, such as zener diodes, and can operate at a maximum reverse voltage of 900V.

The device operates in active mode when it is in standby mode, which is achieved by keeping the input voltage below the protection voltage. When the input voltage exceeds the protection voltage, the device enters active mode and begins limiting the current in order to protect the circuit. The active mode is controlled by an internal timer, which ensures that the current is limited to the maximum permitted level and that the device does not remain in active mode for longer than specified.

Conclusion

The MXLSMCGLCE75A is an integrated device that combines the functionality of multiple diodes and transistors into a single package. It provides overvoltage protection up to 900V, allowing it to be used in a variety of applications. The device is designed to limit voltage transients by operating on the principle that a voltage transient will cause a current flow, bar a specific reverse breakdown voltage. In summary, the MXLSMCGLCE75A is an ideal solution for high-level voltage protection in embedded and portable applications.
