Power Management IC - Hot Swap Controllers

The ISL61863BCRZ-T is a hot swap controller designed for users who need to maintain a controlled power supply under various conditions. The device helps to keep the power delivery system in good shape by managing overcurrent, over-temperature, and other operations as necessary. This protects the input power/peripheral power rail, as well as the load power rail, from potential danger or destruction.

Features of the ISL61863BCRZ-T

• Absolute Maximum Ratings range from -0.3V to 7V for Input Voltage
• Operating Temperature range from -40°C to +85°C
• Automatic soft-start
• Overtemperature protection
• Overvoltage protection
• Two-phase power-good
• On-time measurement
• Pre-bias start-up
• 2.5V-5.5V Internal Reference

Application of the ISL61863BCRZ-T

The ISL61863BCRZ-T hot swap controller is designed to provide overcurrent protection and temperature sensing for applications that require reliable power supply. It can be used in a variety of power systems and is ideal for different types of servers, such as blade servers and rack servers, as well as computer motherboards, digital video surveillance systems and high-density telecom switching systems. It is also suitable for various branch circuit protection applications, such as Ethernet modules, daughter boards, and hard drives.

Working Principle of the ISL61863BCRZ-T

TheISL61863BCRZ-T hot swap controller is a programmable controller that controls the overcurrent, over-temperature, and other operations. The device is designed to monitor the power supply system, detect any irregularities in the current and voltage levels, then operate accordingly. It supports three protection modes: overcurrent, overvoltage, and overtemperature. The device monitors the input power/peripheral power rail, load power rail, and the external temperature sensor. When any of these parameters are violated, the controller will power down or limit the current to protect the system from damage. As a result, the ISL61863BCRZ-T hot swap controller helps to maintain a safe and secure power supply at all times.

Conclusion

The ISL61863BCRZ-T hot swap controller is a programmable power supply management tool designed for user who need reliable and consistent power supply. It supports three protection modes, namely overcurrent, overvoltage, and overtemperature, to protect the peripheral power rail, load power rail, and input voltage from danger or destruction. The device can be used in a variety of applications and is suitable for servers, computer motherboards, digital video surveillance systems, and high-density telecom switching systems.
