The LTC1647-2IS8 is a sophisticated dual channel hot swap controller designed by Linear Technology, now part of Analog Devices, to manage the safe insertion and removal of boards in live backplane environments. This integrated circuit helps in preventing glitches on the power supply rail by controlling the inrush current during the insertion of electronic modules.
Key Features:
- Integrated Dual Channel: The LTC1647-2IS8 features two independent channels, allowing for the control of two separate supply voltages simultaneously. This is particularly useful for systems that require different voltages for analog and digital circuits.
- Adjustable Inrush Current Control: With external resistors, users can set the inrush current limit, enabling the customization of the power-up sequence for specific requirements of the load.
- Overcurrent Protection: The device provides robust protection against overcurrent conditions, safeguarding both the power source and the electronic components on the board.
- Power Good Output: Each channel has a 'power good' output signal, which indicates when the output voltage is within a specified range, ensuring that the system operates only when stable power is available.
- High Voltage Operation: The LTC1647-2IS8 can handle a wide range of supply voltages, making it versatile for various applications.
- Compact Package: Available in an 8-lead SOIC package, the LTC1647-2IS8 is designed for space-constrained applications.
