.Introduction
A Hot Swap controller is an integrated circuit (IC) that safely controls the process of inserting and removing a circuit board or other type of module into an electrically powered system. Hot Swap controllers provide protection against overcurrent, overtemperature, undervoltage and other potentially hazardous conditions while allowing individual boards to be hot-swapped. LTC1647-2CS8#TRPBF is a Hot Swap controller designed by Linear Technology, which can be used with a wide range of applications.Applications
The LTC1647-2CS8#TRPBF can be used in a wide array of applications including but not limited to, portable and embedded systems, server and storage, telecommunications and networking and industrial automation. Possible applications for the LTC1647-2CS8#TRPBF include:- Hot swap power applications
- High-power, low-voltage supplies
- Battery operated systems
- Charge pump and DC-DC converters
- Power line telemetry
- Automotive systems
Feature
The LTC1647-2CS8#TRPBF offers a range of features designed to protect its user’s circuit as well as provide a range of capabilities. These include:- High Efficiency Automated Fault Monitoring - Output voltage, current, and temperature can be measured and monitored without compromising system performance.
- Voltage and Current Limiting - The device provides powers limits and current limiting protection that can be used to set a safe operating range and protect against overloads.
- Safety System - The device is designed to move from an off state to a current-limited/fault-protected state as soon as power is applied, preventing high currents from flowing into the controlled circuit during hot-swap operations.
- Over-temperature protection - Thermal protection is provided by the device’s thermal shutdown circuitry and adjustable thermal limit.
- Input UVLO Protection and Input Reverse Polarity Protection - The device can be used with AC and DC input voltages, and includes an Input Undervoltage Lockout Protection that notifies the user when the input voltage is too low.
- Fast Transient Response - The device is designed to respond to fast transients (e.g. brownouts) with speed and accuracy, protecting against voltage drops and surges.

Working Principle
The working principle of the LTC1647-2CS8#TRPBF controller is based on a modified PI (proportional-integral) controller. The PI controller adjusts the output voltage according to the input voltage, and the feedback received from the output voltages and currents. The main goal of the PI controller is to maintain the output voltages within the required range, while also providing protection against input voltage and current spikes.At start-up, the LTC1647-2CS8#TRPBF controller monitors the input voltage and output voltages and current. If the input voltage is within the acceptable limits, the device outputs a charging current to the output voltage and current loops, in order to charge the load. The PI controller then adjusts the output voltage and current until it reaches the desired level.When the input voltage or current drops below or above the limits, the device enters the fault protection state, in which it limits the output current and shuts off the power. This process provides protection against harmful overcurrent and overvoltage conditions.The LTC1647-2CS8#TRPBF is designed to protect against thermal runaway, in which the output current may exceed the rated limit due to excessive heat. For example, if the temperature of the device exceeds 125°C, the thermal protection circuitry inside the device automatically shuts off the power to the circuit, thus protecting it from damage.Conclusion
The LTC1647-2CS8#TRPBF is a Hot Swap controller which is suitable for applications that require hot-swapping capability, as well as protection against over-current, over-voltage, under-voltage, input reverse polarity and thermal runaway protection. The device is designed with a modified PI controller, making it very accurate and responsive to input voltage and current fluctuations. It is also able to monitor output voltages and currents, while providing protection against hazardous conditions. Thanks to its small size, the device is suitable for use in space-constrained applications.The specific data is subject to PDF, and the above content is for reference
