The ISL61851LCBZ-T is a hot swap controller, designed to protect sensitive loads from inrush current and overvoltage faults. It is designed to manage the hot swap enabling of devices that require extra protection due to their sensitive nature. The device provides additional safe on/off and overvoltage protection for a variety of hot swappable application including industrial, consumer, and medical electronics.

Application Field for ISL61851LCBZ-T

The ISL61851LCBZ-T is well suited for a variety of applications that require extra protection due to their sensitive nature. This includes both commercial and industrial applications. In addition, it is an important device in medical engineering applications as well, such as providing additional protection for implanted medical devices.

In commercial applications, the ISL61851LCBZ-T is ideal for protecting loads from overvoltage and inrush current on electronic and digital equipment. This includes consumer electronics such as Digital Video Recorders (DVRs), televisions, Point of Sale (POS) devices, and more. In addition, industrial applications that require an added layer of protection, such as remote monitoring systems, automated industrial equipment, and other factory automation, can benefit from the ISL61851LCBZ-T.

In medical engineering applications, the ISL61851LCBZ-T provides an additional layer of protection to sensitive medical implants. These implants are often used to deliver drugs, or to monitor vital signs such as heart rate, oxygen saturation, and more. The ISL61851LCBZ-T can provide the added protection needed to ensure safe operation of these sensitive medical implants.

Working Principle of ISL61851LCBZ-T

The ISL61851LCBZ-T utilizes two main methods of protection for its hot swap applications. The first is a low voltage/current droop system, which helps to protect against inrush current. When the device is turned on, the ISL61851LCBZ-T begins to drop the voltage and current supplied to the load in increments, eventually reaching a steady output. This ensures that the load is not subjected to an excessive start-up current, which could cause it damage.

The second protection system is an overvoltage protection function. This function ensures that the voltage supplied to the load never exceeds an absolute maximum level, regardless of the input voltage that is applied to the device. This helps to prevent damage from overvoltage conditions, and can help to extend the life of the sensitive load.

The ISL61851LCBZ-T also offers other features, such as a soft start function and a power good flag. The soft start function helps to reduce the inrush current when the device is turned on, while the power good flag is used to indicate that the voltage supplied to the load is within a predetermined range.

Conclusion

The ISL61851LCBZ-T is a hot swap controller designed to provide additional protection to sensitive loads that are vulnerable to inrush current and overvoltage faults. It is well suited for a variety of applications, from commercial and industrial to medical engineering, due to its low voltage/current droop and overvoltage protection functions. In addition, the ISL61851LCBZ-T also includes a soft start function and a power good flag, which further increases its versatility and protection. This makes it an ideal solution for a variety of hot swappable applications.
