Hot-swap controllers are power management integrated circuits (PMICs) used to safely power any kind of electronic device. Hot-swap controllers allow very rapid and safe insertion of a device into a power system that is already powered up, eliminating downtime associated with short-circuits or other surges in the line. The TPS24700DGK is a hot-swap controller made by Texas Instruments, and it is widely used in applications such as automotive, computing, industrial, medical and communications devices.

The TPS24700DGK is the first ultra-low-dropout (UL-LVM) single-chip controller that supports current up to 30A. The device is designed with a drop-down voltage-level detector, integrated low-wind safe start circuitry and overtemperature protection to ensure a safe, positive insertion into customer application systems. It provides ultra-low quiescent current and operates from 4.5V to 17V with a dropout voltage of only 0.2V at full current. This helps minimize power loss, which can reduce device temperature and reduce power-related costs.

The device contains a control circuit that monitors the input voltage, output current and temperature. The control circuit is designed to detect any overvoltage or overcurrent conditions and shuts off the device, thereby protecting the system from further damage. In addition, the over-temperature protection feature of the device will detect any thermal emergencies and will shut down the device if needed.

The TPS24700DGK also contains a MOSFET gate driver, which is designed to drive the power MOSFETs in the system. The gate driver provides gate current and voltage protection, as well as low-threshold overvoltage protection. This ensures that the power MOSFETs in the system are protected from overcurrent, overvoltage and overtemperature conditions.

The TPS24700DGK provides a set of complementary use cases that make it suitable for many applications. These include a full-loop thermal shutdown, Over-Temperature and Overvoltage Protection (OTP), Automatic Retry and Automatic Retry on Overshoot (ARO), and Enhanced Current Sense (ECS). These features allow the device to be used in applications where a high degree of protection is required, such as automotive, computing, industrial, medical, and communications devices.

In summary, the TPS24700DGK is a high-performance, single-chip hot-swap controller designed for applications where a high degree of protection and system monitoring are needed. The device features an integrated MOSFET gate driver, drop-down voltage-level detector, integrated low-wind safe start circuitry, and overtemperature protection to ensure a safe, positive insertion into customer application systems. With its wide range of use cases, it is suitable for automotive, computing, industrial, medical, and communications devices.
