PMIC - Hot Swap Controllers are commonly used to protect circuitry from unexpected high inrush currents. The UCC3918DPTR is a high performance hot swap controller that is designed to meet the demands of electronic systems requiring progressively tighter safety specifications. By using an optimized low start-up current, UCC3918DPTR provides maximum thermal protection while minimizing board footprint.
The UCC3918DPTR uses a voltage comparator, a totem pole output stage, reference current sources, and a set of precision resistors to monitor the presence and line voltage of the system load. It switches the power on and off for the system load in order to provide maximum protection against anything that could be input into the system that could overload it.
The UCC3918DPTR has two levels of hot swap protection – monitoring the load current and monitoring the system power. The load current sensing circuit uses a precision resistor divider network and a voltage comparator to compare the load current with a threshold level, and the system power sensing circuit using a precision resistor divider network and a voltage comparator to compare the system voltage with a threshold level.
The UCC3918DPTR features a fast response time and a fast turn-on time. It also has an adjustable retry start-up count which allows the system power to be asserted up to three times, giving the system the capability to handle brief spikes in input power. In addition, it features reverse insertion protection to prevent hot-swapping the power lines in the wrong direction.
The UCC3918DPTR offers a wide variety of protection features for power systems. It contains over-temperature protection, over-current protection, electric shock protection, and reverse insertion protection. It also contains an adjustable turn-off delay to provide additional flexibility in transitioning from one system state to another. In addition, the UCC3918DPTR has a watchdog timer which will automatically reset the device in case it encounters any failures.
The UCC3918DPTR is an ideal choice for applications where power control and safety are top priority. It is designed for use in an array of systems requiring load protection such as computer motherboard power management, server power management, industrial power systems, and LCD inverters. The device can be used in conjunction with smart lithium-ion batteries, as well as uninterruptible power supply systems.
The UCC3918DPTR is a robust hot-swap power management IC that provides an efficient and reliable solution for regulating power in systems. It features protection against overloads, underloads, and overtemperature conditions, and a set of features to protect against electrical shock, reverse insertion, and watchdogs. It is an affordable choice for a wide variety of applications.
