HOTSWAP OPERATIONS FOR PROGRAMMABLE LOGIC DEVICES

Techniques are provided to control hotswap operations with programmable logic devices (PLDs). In particular, a MOSFET is provided to limit an in-rush current drawn from a power supply by capacitive components of an electronic assembly when it is plugged into the live, power supply. A controller with an algorithm is provided to control the MOSFET based on the in-rush current detected at the MOSFET. As such, a feedback control loop is established to selectively bias the gate of the MOSFET based on the detected in-rush current. The algorithm may limit the in-rush current based on a Safe Operating Area (SOA) of the MOSFET. The hotswap process may include multiple phases each with a voltage and/or current limit modeling the voltages and currents of the SOA. The algorithm may transition through the phases with the respective current and/or voltage limits during the hotswap process. 本发明涉及用于可编程逻辑装置的热插拔操作。提供技术以控制采用可编程逻辑装置(PLD)的热插拔操作。特别地，提供MOSFET以限制当插入通道电源时由电子组件的电容性部件从电源吸取的突入电流。提供具有算法的控制器以基于在MOSFET处检测到的突入电流而控制MOSFET。如此
