Introduction to Hot Swap Controllers

A hot swap controller is a chip used to allow safe replacement of electronics while they are still powered. The device works by cutting off the power supply once the power draw exceeds a certain threshold, or when an over-current or short-circuit condition is detected. Hot-swap controllers are usually used on printed circuit boards (PCB) to protect against unexpected damage or malfunctions of the circuit.

TPS259520DSGT

The TPS259520DSGT is a Texas Instruments hot swap controller. It is a compact, single-channel device that can be used to safely connect one device to a supply voltage. The TPS259520DSGT features under-voltage lockout, over-current protection, fault output, and multiple circuit protections.

Application Field

The TPS259520DSGT can be used for a wide range of applications including consumer electronics, industrial, automotive, and medical. It is ideal for high-density systems where power management is essential, and it offers protection against circuit damage or faults. In consumer electronic applications, the TPS259520DSGT can be used to safely power displays, memory modules, and other high-power devices. In medical applications, the device can provide over-current protection to protect patient-connected equipment.

Working Principle

The TPS259520DSGT works by monitoring the input voltage and current. When the voltage drops below a certain threshold, or when an over-current or short-circuit condition is detected, the device will shut off the output. On top of this, the device also features programmable over-voltage and under-voltage limits, making it suitable for a variety of power supply applications.

Conclusion

The TPS259520DSGT hot swap controller from Texas Instruments is a versatile and reliable device for connecting one device to a supply voltage. It is capable of providing over-voltage, under-voltage, over-current and short-circuit protection, making it suitable for a variety of applications including consumer electronics, industrial, automotive and medical.
