PMIC - Hot Swap Controllers
The UCC3917N is an integrated Power Management IC (PMIC) designed for hot-swap applications that require input protection, current limiting and operational accuracy. It can provide up to 96W of power with up to 200V of input voltage, using a wide range of voltage, current, and power ratings. This PMIC also has a temperature operating window of -20C to 105C, and is capable of toggling up to 35V of output voltage. With a high-efficiency switching design and optimized loop compensation, the UCC3917N is designed to ensure optimal operation.
Applications
The UCC3917N has a variety of applications, and is ideal for hot-swap circuit applications that require input and output protection, current limiting and operational accuracy. These include machines and equipment for industrial applications such as home appliances, HVACs, electric vehicles and medical equipment. It can also be used for general commercial hot-swap circuits for enhancing the reliability and accuracy of system operations, monitoring and control.
Working Principle
The UCC3917N switch operates by detecting the input voltage and the amount of load current on a load. Depending on the level of the load current, the controller will then adjust the power stages to keep the output voltage within a specified range. The controller implements a high-voltage single-cycle transient response. This feature enables the controller to respond quickly to changes in load current. The controller also has a logic-controlled foldback that helps to reduce the inrush current during switch-on. In addition, it includes an internal error amplifier, as well as a temperature monitoring circuit and undervoltage lockout, which help to provide a high degree of control and protection. The internal error amplifier monitors the output voltage and compares it to a reference voltage to provide accurate output voltage control.
Benefits
The UCC3917N is designed to provide reliable and accurate operation, as well as to reduce unwanted power dissipation and improve overall system efficiency. It provides safe and precise current limit, precise voltage regulation and low output ripple, along with an adjustable over-current protection and thermal protection. Additionally, it has an integrated self-imposed switching frequency shift, providing better performance and improved system reliability in high temperature environments.
