PMIC - Hot Swap Controllers have become a necessary safety measure for a wide variety of electronics, which require a secure and durable solution for managing power connections. The UCC3915NG4 is a unique hot-swap controller from Texas Instruments that provides the features needed to safely connect and disconnect a power supply from live systems, both in industrial and consumer applications. This device offers a wide range of features to ensure safe and reliable operation, as well as an auto-retry feature for improved protection.

The UCC3915NG4 Hot Swap Controller provides over-current protection and auto-retry functions in order to protect the connected systems from any kind of overloads. It also has integrated low-power dissipation and high-efficiency circuitry, which allows to reduce the power losses up to 95% when the device is on and delivering the constant current. Additionally, it contains a user-programmable auto-retry feature that can be set to two different frequencies to avoid the board becoming alive and cause any kind of damage.

The UCC3915NG4 Hot Swap Controller is designed for a wide variety of applications, ranging from industrial equipment to consumer electronics. It supports voltages up to 36V, which makes it an ideal choice for applications such as servers, storage, and telecommunication systems. The device also features a low output voltage rise time, which ensures that the load safely transitions from low to high voltage without potential glitches. Besides, its low suppress voltage, wide delay time range, and fast loop response time are essential characteristics essential to meet the dynamics of the system.

In addition, the UCC3915NG4 Hot Swap Controller is provided with a Power-Control-Fault (PCF) pin that helps to reduce the unwanted currents through the device due to an abnormal input voltage. The PCF pin can be used to put the device into an off-state, which prevents it from switching on until the power supply is stable. Moreover, an integrated over-temperature protection feature helps to protect the system from any type of thermal damage in case of excessive temperature. Finally, a high-speed digital solenoid output isolator helps to reduce the switching time of the internal circuitry by over 70% for improved reliability.

Overall, the UCC3915NG4 Hot Swap Controller provides overvoltage protection and reliable power delivery, while using the auto-retry feature and the PCF pin to protect the connected systems from any potential damages. The device is suitable for a wide variety of applications, and offers low power dissipation and high efficiency, allowing up to 95% power saving when delivering constant currents. It has low output voltage rise time and fast loop response time, which minimizes potential glitches and helps the load transition from low to high voltage without any issues. Finally, the integrated over-temperature protection and the high-speed digital solenoid output isolator help to improve the overall reliability and safety of the system.
