The UCC3913DG4 is a hot swap controller (PMIC) used to control power to a system or device and protect it from overcurrent or short-circuit related damage and destruction. It serves as a single-chip solution for thermal-limited systems, allowing the system to be safely powered down in the event of any electrical fault. The device is designed to automatically limit the current drawn from a remote power supply, providing robust protection and improved system reliability.

The UCC3913DG4 can be used in a variety of applications including distributed DC/DC converters, pluggable power supplies, adaptor power supplies, and telecom/telephony equipment. It is especially useful in medical applications, due to its ability to quickly and accurately detect and respond to overcurrent or short-circuit events. This leads to enhanced system reliability and improved patient safety.

The UCC3913DG4 is based on a monolithic CMOS process and includes the necessary components and circuitry to allow the device to operate as a hot-swap controller. The design of the device integrates a configurable gate drive, adjustable current limit, overvoltage and undervoltage detection, as well as a wide-range power-on reset that ensures a reliable power-up sequence.

The hot-swap controller is designed to facilitate efficient power management at the point of load. This is achieved by monitoring the incoming voltage and current associated with the load and protecting against overcurrent events by limiting the current drawn from the power supply. When the load begins to draw more than the current limit of the controller, the gate drive output is triggered, disabling the gate voltage to the power device.

The UCC3913DG4 also provides precise overvoltage and undervoltage protection via its adjustable threshold inputs. In addition, the device offers soft-start current limiting, enabling low-current startup of the power supply. This allows a high-current supply design to be used while still providing the safety and ease of operation associated with low-current startup.

Overall, the UCC3913DG4 is a highly-integrated hot swap controller (PMIC) that is designed to protect systems and devices from overcurrent and short-circuit related damage and destruction. It offers robust protection and improved system reliability, along with precise overvoltage and undervoltage protection. The device can be used in a variety of applications, and is especially useful in medical applications due to its ability to quickly and accurately detect and respond to overcurrent events.
