ISL61863DIRZ-T

Introduction
ISL61863DIRZ-T is a Hot Swap Controllers from the Power Management IC (PMIC) family. It’s designed to provide protection of the system when it’s connected and disconnected from the load. The device continuously monitors the power supply voltage and current, and provides over-voltage, over-current, and over-temperature protection. This Hot Swap Controller also has an on-off control, so it can be used to control the power-on sequence of boards and cards. In addition, the device is RoHS compliant, reducing its environmental impact.Features
The ISL61863DIRZ-T Hot Swap Controller provides several features to protect your system, including:

• Over-voltage protection (OVP)
• Over-current protection (OCP)
• Over-temperature protection (OTP)
• On-off control for sequence control
• Adjustable soft-start
• Intelligent sequencing
• I2C Slave Interface

Applications
ISL61863DIRZ-T Hot Swap Controller is ideal for applications that require the disconnection and reconnection of a system from a load or power source, such as server systems, power supplies, and network switches. Its features provide protection against over-voltage, over-current and over-temperature. It also allows for precise control of power-on sequence and intelligent sequencing of boards and cards.Working Principle
The ISL61863DIRZ-T Hot Swap Controller continuously monitors the voltage and current of the system, and uses the on-off control to provide precise control of the power-on sequence. The device is also equipped with an adjustable soft-start with intelligent sequencing. The device has a programmable delay that prevents any excessive inrush current when power is connected to the system.When the input voltage exceeds a pre-defined threshold, the Hot Swap Controller will turn off the MOSFET in order to give over-voltage protection. The threshold for over-current protection is programmable, and when the current exceeds this limit, the MOSFET will be turned off. The device also has an adjustable threshold for over-temperature protection, which will turn off the MOSFET when the temperature exceeds the limit. The device also has a programmable delay to avoid excessive inrush current.Conclusion
The ISL61863DIRZ-T Hot Swap Controller from the Power Management IC (PMIC) family is designed to provide over-voltage, over-current, and over-temperature protection, as well as precise control of the power-on sequence. It also features an adjustable soft-start and intelligent sequencing. The device is ideal for systems that require the connection and disconnection of load and power sources, such as servers, power supplies, and network switches.
