LTC1421ISW#PBF - Hot Swap Controller from Linear Technology

The LTC1421ISW#PBF is a sophisticated hot swap controller designed by Linear Technology, now part of Analog Devices, to allow safe board insertion and removal from a live backplane. This integrated circuit is essential for applications where system maintenance and serviceability are critical without the need to power down the entire system. The device operates with a supply voltage range of 2.7V to 12V, making it versatile for various applications.

Key Features:

    
• Adjustable Supply Voltage: The LTC1421ISW#PBF can operate with supply voltages ranging from 2.7V to 12V, accommodating a wide array of systems and power requirements.
    
• Electronic Circuit Breaker: This feature ensures protection against overcurrent conditions by limiting the output current to a safe level set by the user.
    
• Programmable Timer: A programmable timer allows for adjustable overcurrent auto-retry delay, providing flexibility and control over the fault recovery process.
    
• Under Voltage Lockout (UVLO): The UVLO function ensures that the device operates only when the input voltage is within a specified range, protecting downstream components from low voltage conditions.
    
• Thermal Shutdown: To prevent damage from overheating, the LTC1421ISW#PBF includes a thermal shutdown mechanism that disables the external MOSFET when the die temperature exceeds safe limits.
    
• Status Indicators: The device features status flags that provide real-time feedback on the operation conditions, such as overcurrent and power good status.
