ADM1275-1ACPZ Application Field and Working Principle

The ADM1275-1ACPZ is a hot-swap controller designed for use in hot-swap applications. It is designed to safely and reliably insert board-level components into live systems, where possible current and field levels could be damaging or damaging even with an energized bus or system on the load side.The controller features an on/off switch control of two independent stages. Both stages include an adjustable current limit, over-temperature protection, over-voltage protection and under-voltage lockout. The ADM1275-1ACPZ also includes internal fault logging, independent fault-indication outputs, and a programmable interrupt output.In operation, the ADM1275-1ACPZ provides two main functions–first, it monitors the input voltage and current and if a fault condition is detected, it will automatically shutdown the board-level components. It also monitors the hot-swap bus current, temperature and voltage faults and can independently control its on/off switch.The ADM1275-1ACPZ uses an input voltage range of 4.5 v to 28 v and an operating temperature range of -40 °C to +80 °C. It is designed for use in extreme temperatures and environments and is an ideal choice for applications where reliability and protection of board-level components are important.In terms of the working principle of the ADM1275-1ACPZ, the controller monitors the input voltage and current with two on/off switch control stages. This ensures that all board-level components inserted into the board are protected from any fault conditions such as over-voltage, over-temperature or under-voltage, which can damage the components.The ADM1275-1ACPZ also includes independent fault-indication outputs and programmable interrupt output. This allows the user to be alerted to any fault condition, enabling them to take corrective action in time. In the case of an over-voltage fault, the controller will shut down the board-level components, preventing further damage.Overall, the ADM1275-1ACPZ is a hot-swap controller designed for use in hot-swap applications. It has a reliable and robust design, making it an ideal choice for applications where reliability and protection of board-level components are important. It is designed for use in extreme temperatures and environments, making it suitable for deployment in a variety of demanding scenarios.
