ISL6152CBZA-T Application Field and Working Principle

Introduction

The ISL6152CBZA-T is a hot swap controller designed to provide low loss system protection against overcurrent conditions for systems requiring application specific sensing and control. It provides the capability to support the protection of each individual load in the system with its current sensing reporting capability. This part is classified as a PMIC - Hot Swap Controller, and it is fabricated using low power CMOS process.

Features

This hot swap controller offers numerous features, designed to make it the perfect fit for its usage scenarios. These features include:• Input voltage range of 2.5V to 6V• Overcurrent protection up to 30mA• Undervoltage lockout protection• Low power supply current• Low voltage operation for maximum efficiency• SOIC-8 package

Application Field

The ISL6152CBZA-T is an ideal choice for hot swap applications, such as those in small embedded applications. This part is perfectly suited for use in systems requiring low-loss sensing and control of the power supply. It is often used in systems requiring protection from overcurrents and undervoltages, such as portable electronics, and embedded computers.

Working Principle

The ISL6152CBZA-T uses an innovative sensing circuit to monitor the current in the system, which then triggers the corresponding control signal to activate the protection circuits. The control signal is determined by a voltage correction signal, which is derived from the external voltage source. This voltage correction signal is then compared to the current signal, and if the external voltage exceeds the acceptable voltage range, the device will shut down the system to protect it from damage.The device also features a wide range of overcurrent protection settings, allowing the user to set the amount of protection the system requires. It can also be programmed to allow the user to choose what time delay they would like the system to shut down in the event of an over-current.

Conclusion

The ISL6152CBZA-T is a hot swap controller designed for low-loss system protection against overcurrents. It offers a wide range of features, including wide input voltage range, low power supply current, SOIC-8 package, and variable overcurrent protection. The device is perfect for any application requiring efficient power supply protection, making it an excellent choice for hot swap applications in small network embedded systems.
