TVS components are essential to protect electrical systems from high-speed power surges. In the electronic industry, there is an ongoing need for more comprehensive protection solutions. ISA2412 from Infineon Technologies is an advanced DC-to-DC converter designed to provide exceptional protection against transient voltage surges. This article provides an overview of the ISA2412 application field and working principle.

What is ISA2412?

ISA2412 is a highly integrated DC-to-DC voltage converter integrated circuit (IC) designed to provide reliable surge protection for electronic circuits exposed to transient electrical power surges. It is RoHS compliant, which means that it is compliant with restricted materials guidelines. It is designed to provide an improved level of protection from transient voltages up to 24V DC. In addition, it features a fast response time, low quiescent current and a wide input voltage range of 4.2V-20V DC.

Application Field

ISA2412 is suitable for a wide variety of applications, including TV sets, automotive electronics, communication equipment, medical devices, and consumer goods. This integrated circuit can provide reliable protection for circuits exposed to transient voltage surges, often referred to as Electrostatic Discharge (ESD). It has the ability to detect transient voltage peaks and shut down the system until the transient voltage dissipates.

In automotive applications, ISA2412 can provide a safer and energy-efficient solution for DC-DC converters. It can be used to protect the auto ignition system from overvoltage and reduce the current consumption of the vehicle’s electrical system. It can also be used to protect infotainment systems, instrument clusters, navigation systems, and other automotive electronic systems.

Working Principle

The ISA2412 works by clipping the incoming transient voltage peaks. It uses a fast response time and wide input voltage range to provide reliable surge protection. When the power supply is connected, the ISA2412 starts to detect any transient voltage peaks. It then quickly lowers the voltage to a level where no damage will occur. It then waits until the input voltage returns to within the acceptable range, and the system can be powered again.

When the supply voltage reaches its normal range, the ISA2412 adjusts the output voltage to the desired operating level. This allows the system to reset and power the connected system. In this way, the ISA2412 protects the system from overvoltage and provides a reliable power supply.

Conclusion

ISA2412 from Infineon Technologies is an advanced DC-to-DC converter designed to provide exceptional protection against transient voltage surges. It has a wide variety of applications, including automotive, communication, medical, and consumer electronics, and it offers a reliable and energy-efficient solution for DC-DC converters.

The ISA2412 works by clipping the incoming transient voltage peaks and adjusting the output voltage to the desired operating level. It quickly lowers the voltage to a level where no damage will occur and waits until the input voltage returns to within the acceptable range before resetting the system and powering it back up. In this way, the ISA2412 can provide reliable and effective surge protection for circuits exposed to transient voltage surges.
