The TPS259240DRCT is a Power Management IC (PMIC) designed for Hot Swapping applications, developed by Texas Instruments. This device provides simple circuits with integrated protection, monitoring and current control for six channels of hot swapping. In one package, it provides several functions for each hot swap channel, including automated on/off, current limiting, power limiting, and power dissipation preventing, along with integrated power good signals. The features of this IC make it ideal for hot-swap applications, such as server, storage, router or power distribution systems.

Features of TPS259240DRCT

The TPS259240DRCT consists of six hot swap channels and a low on-resistance switch to control the HOT_OFF signal. The six channels offer a wide range of features, such as:

• High efficiency switch with up to 0.7% on resistance
• Integrated current-sensing loops
• Digital slave I2C interface
• Programmable terminal voltage and current settings
• Programmable current limits for each channel
• Protection and monitoring for overvoltage, under-voltage, over-current, and over-temp
• Unique hot swap power good signals for each channel
• Input power conditioning with advanced power fail-safe

Working Principle of TPS259240DRCT

The TPS259240DRCT is a hot swap power controller, which allows devices to be hot swapped or replaced while a system is powered on. This device is able to manage the power up and shut down sequences of individual devices, to ensure their smooth and reliable operation.The primary function of the TPS259240DRCT is its voltage and current sensing circuits, which allow the IC to regulate the voltage and current of the devices being hot swapped. The IC also performs a series of protection functions, such as over-voltage, under-voltage, over-current, and over-temperature protection, which helps to protect the devices from damage.The TPS259240DRCT also has an integrated I2C interface, which allows for configuration and control of the device. The interface is used to set the voltage and current limits, enable or disable channels, and monitor the status of various protection events. The TPS259240DRCT also has a unique power good signal for each channel, which indicates when the power is being supplied to the channel.

Conclusion:

The TPS259240DRCT hot-swap controller from Texas Instruments is an ideal solution for hot-swap applications, such as server, storage, router or power distribution systems. The device provides six channels of hot swapping with automated on/off, current limiting, power limiting, and power dissipation prevention, along with integrated power good signals. The device also performs several protection functions, such as over-voltage, under-voltage, over-current, and over-temperature protection. In addition, the TPS259240DRCT features an I2C interface which allows for configuration and control of the device.
