Introduction to Hot Swap Controllers

Hot Swap Controllers are extremely useful products in the field of Power Management Integrated Circuit (PMIC) which use multiple control and protection mechanisms to allow safe power and signal interconnections between two power sources. Hot Swap Controllers prevent the large inrush current which could be harmful to the power source and the power receiving equipment, by allowing the power to slowly ramp up and monitor the power levels while they are being exchanged to the desired level.

TPS259570DSGT Application Field

The Texas Instruments TPS259570DSGT Hot Swap Controller is an ultra-low power Hot Swap Controller based on the Texas Instruments Digital Telecom Code (DTI) platform which combines high accuracy system monitoring and protection with high performance power management capabilities. It is a highly integrated device with 26 serially-controlled channels for Voltage and Current Sensing, Temperature Sensing (TSense), Gate Driving, Fault Detection and Management. It is suitable for applications where low power, high accuracy and robust protection are crucial. The TPS259570DSGT Hot Swap controller is well-suited for applications including automotive, industrial, telecoms, and computing applications where hot-swapping of a supply voltage is required.

TPS259570DSGT Working Principle

The TPS259570DSGT Hot Swap Controller is a single-chip controller which combines multiple power management functions such as voltage, current and temperature monitoring, fault detection, over-current protection, surge protection and power-on/off delay. It provides a full interoperability between the various power sources and the Hot Swap Controller, allowing a reliable power delivery to the connected device. The Hot Swap Controller uses multiple methods to protect the connected devices, such as by controlling the current and voltage-ramp rates, thermal protection, and slew rate control, etc. It also provides an accurate monitoring of all parameters, including the supply voltage, load current, and temperature, allowing a safe and uninterrupted power flow. The TPS259570DSGT Hot Swap controller also has advanced fault detection modes which can detect any abnormal conditions, such as a short-circuit caused by external over-currents, and shut down the circuit to protect it from potential harm.

Conclusion

The TPS259570DSGT Hot Swap Controller is a highly integrated Hot Swap Controller which combines low-power architecture and multiple protection mechanisms with accurate system monitoring and protection. It is well-suited for applications requiring hot-swapping of a supply voltage, such as in automotive, industrial, telecoms, and computing applications. The TPS259570DSGT Hot Swap Controller can also provide reliable and safe power delivery to connected devices, with its advanced protection and fault detection modes.
