Product Overview: LTC4252CIMS-2#PBF

The LTC4252CIMS-2#PBF from Linear Technology is a sophisticated negative voltage Hot Swap™ controller that allows a board to be safely inserted and removed from a live backplane. Utilizing external N-channel MOSFETs, the controller provides power to the board without causing any disturbances to the backplane power rail.

Key Features

• Integrated Charge Pump: The device features an onboard charge pump that eliminates the need for an external power supply to drive the gate of the N-channel MOSFETs, ensuring efficient operation and reduced component count.
• Adjustable Overcurrent Protection: The LTC4252CIMS-2#PBF offers an adjustable overcurrent function with a circuit breaker that provides reliable protection for the system components.
• Under-Voltage Lockout: An under-voltage lockout (UVLO) feature ensures that the Hot Swap operation only occurs when the supply voltage is within an acceptable range, preventing damage due to insufficient power.
• Overvoltage Protection: The device also includes overvoltage protection to safeguard the load from transient voltage spikes.
• Compact MSOP Package: The LTC4252CIMS-2#PBF is available in a compact 10-lead MSOP package, which is suitable for space-constrained applications.

Applications

Designed for a wide range of applications, the LTC4252CIMS-2#PBF is ideal for use in:

• Telecommunications Equipment
• Network Servers and Routers
• Industrial Systems
• Datacom Infrastructure
