PMIC - Hot Swap Controllers are power management solutions that protect sensitive electronics from overload. UCC2919PW is a hot swap controller from Texas Instruments (TI) that is provided to provide protection from an output overload. This hot swap controller provides scalable output current and a wide range of device options for improved system safety.

UCC2919PW hot swap controller utilizes precision current-sensing circuits and adjustable current limit. When the load exceeds the set current limit, it disconnects the power to prevent further damage. The controller also features automatic insertion and removal of the load into the circuit.

The UCC2919PW hot swap controller is useful in a variety of applications, such as:

• Power supply controllers
• Battery protection systems
• Overvoltage protection circuits
• Power distribution networks
• Memory card readers

The UCC2919PW hot swap controller works using a simple three-step process. The first step is to detect the input voltage. Once the input voltage reaches the specified level, the controller enters a “Power On” state. In this state, the controller monitors the output current and compares it to the set current limit. If the current exceeds the limit, the controller enters a “Fault” state and disconnects the power.

The next step is to determine the type of fault. The UCC2919PW can detect several types of faults, including an overcurrent, an overvoltage, an overtemperature, and an undervoltage condition. If any of these faults are detected, the controller enters the “Fault” state and disconnects the power. The controller then determines the cause of the fault and takes action to correct it, such as adjusting the output voltage or the current limit.

The last step is to reset the controller. The UCC2919PW controller has an onboard reset circuit that can be used to reset the controller when the fault condition is resolved. The reset circuit can also be used to enable manual control of the controller. Once the controller is reset, it re-enters the “Power On” state and resumes normal operation.

The UCC2919PW hot swap controller is a highly efficient and effective solution for protecting sensitive electronics from damage due to overvoltage, overtemperature, or overcurrent. The controller is easy to use and is compliant with the industry standards for greater safety and reliability. Whether used for power supply or power distribution, the UCC2919PW provides a robust and reliable solution that works reliably in a wide range of applications.
