Introduction to ISL61861CCBZ

ISL61861CCBZ is a highly integrated hot swap (HS) and power management integrated circuit (PMIC). This chip is designed and manufactured by Intersil. It is a multi-phase, high-side HS device with integrated smart power stages (SPS). These are primarily used in telecommunications and computer applications including Point-of-Load (POL) and server applications.

Application Field

The application field of ISL61861CCBZ includes power management and hot swap in telecommunications, consumer, computing and desktop systems, such as laptops, servers, disk drives, Ethernet switches, and routers. It also finds application in xDSL, DSL, optical transceiver, and load switching.

Working Principle

The ISL61861CCBZ is an advanced multi-phase, high-side, hot swap controller. It provides a means to efficiently and safely bring a system into operability, by guarding against system faults, overcurrent conditions, and undervoltage conditions.The ISL61861CCBZ first enables the power supply when it is externally enabled and the system voltages are within their prescribed limits. It then monitors current, system voltage, and DC input voltage. If an overcurrent condition arises, the ISL61861CCBZ will direct the output drivers to shut off the system. Also, if the system’s voltages are below their predetermined level, the ISL61861CCBZ will shut off the power to the system.The ISL61861CCBZ also has a power up delay function to prevent false power up and shutdown conditions.

Conclusion

To conclude, Intersil’s ISL61861CCBZ hot swap and power management integrated circuit offers a reliable and efficient solution for hot swap and power management needs in telecom, consumer, computing, and desktop systems. The chip provides an easy-to-use, highly integrated circuit for managing system power, enabling systems to run reliably, efficiently, and safely.
