PMIC - Hot Swap Controllers

The TPS259240DRCR is a Hot Swap Controller from Texas Instruments. This device is part of TI\'s robust portfolio of power solutions and devices, and is designed to provide the best power solutions to a wide range of applications. Hot swap controllers are designed to provide overcurrent protection, thermal protection, and output voltage control. The TPS259240DRCR can provide up to 18A of load current and has an adjustable output voltage range of 4.85V to 5.45V.

Application Field

The TPS259240DRCR is a hot swap controller most suited for data center applications, or any other application that requires reliable current management. The device offers over-temperature protection and output voltage control, which make it an ideal solution for server and storage equipment located in large data centers. The device can also be used in industrial, automotive, and medical applications, where over-current and/or over-temperature protection is required.

Working Principle

The primary function of the TPS259240DRCR is to provide reliable current protection in applications where the power supply may not be able to handle the total amount of power needed. The device uses an integrated high-frequency BMOS switch between the input voltage and the output voltage. The switch is controlled by an internal current sense amplifier, which monitors the current drawn from the output. When the current reaches a certain threshold, the switch is turned off and the output voltage is disconnected from the input voltage.

The device also includes an over-temperature protection feature, which monitors the temperature at the device. If the temperature exceeds a certain threshold, the device will shut off the output voltage. This ensures that the device does not overheat, which could cause permanent damage or lead to a catastrophic failure.

The device also features an adjustable output voltage. This can be set to a minimum of 4.85V and a maximum of 5.45V. This allows the user to customize the output voltage to match the needs of the application.

Conclusion

The TPS259240DRCR is an excellent Hot Swap Controller from Texas Instruments, offering reliable power management and protection, adjustable output voltage, over-current protection, and over-temperature protection. This device is ideal for any application that requires reliable power management and protection, such as data centers, industrial settings, automotive, or medical applications.
