The LTC4252-2CMS#PBF is a sophisticated negative voltage hot swap controller designed by Linear Technology, a brand of Analog Devices, to manage the insertion and removal of boards in live backplane systems. This component ensures safe and controlled power-up sequences for -48V and -60V supply rails commonly found in telecom and server environments.

Key Features

• Supply Voltage Range: The device operates with supply voltages ranging from -9V to -80V, making it versatile for various negative supply voltage applications.
• Adjustable Current Limit: Users can set the current limit threshold through an external resistor, providing flexibility to accommodate different board requirements.
• Overcurrent Protection: The LTC4252-2CMS#PBF includes a circuit breaker function that protects the system from overcurrent conditions, enhancing the reliability and longevity of the application.
• Automatic Retry or Latch Off: Upon fault detection, the device can be configured to automatically attempt to restart the power or to latch off, depending on the application's needs.
• Gate Drive for External N-Channel MOSFET: The controller provides a gate drive for an external N-Channel MOSFET, allowing for efficient power management and distribution.
• Under Voltage Lockout (UVLO): The UVLO feature ensures the MOSFET remains off when the input voltage is below a certain threshold, protecting the system from undervoltage conditions.
