The TPS259230DRCR (DRVR) is a Hot Swap (HS) controller IC that provides a safe and reliable power supply for circuit boards. It is suitable for distributed system applications, such as telecommunications and servers, as well as embedded and industrial applications. This IC is designed to protect sensitive circuit components and devices from overcurrent, excessive transients, under-voltage and thermal conditions.

The TPS259230DRCR has programmable settings, allowing users to tune the power levels. It is an ideal solution for distributed system applications, specifically because it can be used to expand the number of power rails available on a circuit board. The HS controllers can be used to switch on and off power sources in order to isolate critical circuit components from overcurrent, excessive transients, under-voltage, and thermal conditions. With its integrated high-side switch and current sense amplifiers, the TPS259230DRCR provides superior power-management flexibility.

The TPS259230DRCR is based on a unique and novel rail-to-rail design. It features DC/DC or AC/DC voltage sources, current sense amplifiers, and an isolation switch. Its self-powered design allows for use in distributed systems. This HS controller IC includes protection against over-voltage, over-current, over-temperature, and under-voltage events. It also provides proportional current and voltage control as well as programmable settings.

The working principle of the TPS259230DRCR is based on a series of limits, which are defined by the user in terms of maximum source voltage, maximum source current, and maximum transient current. These limits are established to protect sensitive components, the circuit board itself, and the environment surrounding the circuit board. When the user-defined limits are exceeded, the TPS259230DRCR will immediately shut off the power supply, thus preventing damage to the components, circuit board, and environment.

In addition, the TPS259230DRCR includes a low-impedance current-sense amplifier for monitoring the power rails. This allows for a very precise control of the power rail, since it is capable of detecting a change in current or voltage as small as 0.15%. The amplifier is able to detect a peak-to-peak current deviation of up to 1 percent, and can detect a peak-to-peak voltage deviation of up to 10 percent.

The TPS259230DRCR also offers protection against thermal runaway, and is designed to operate in a temperature range of –40°C to 85°C. Additionally, the IC supports auto-restart and energy limiting functions, allowing it to efficiently manage power in demanding applications.

The TPS259230DRCR is an advanced Hot Swap controller IC that offers expandable power sources, integrated current sense amplifiers, isolation switch, accurate voltage and current control, and outstanding thermal protection. It is designed for use in distributed system applications, embedded and industrial systems, telecommunications, servers, and other critical applications.
