Product Overview: LTC4252BCMS-1#PBF from Linear Technology

The LTC4252BCMS-1#PBF is a sophisticated negative voltage Hot Swap™ controller designed by Linear Technology to enable safe board insertion and extraction for systems with a negative supply voltage. This integrated circuit provides a controlled power-up sequence, which helps in preventing glitches on the power supply rail and protects both the backplane and the card from damage due to inrush currents or short circuits.

Key Features

• Hot Swap Control: The LTC4252BCMS-1#PBF allows a circuit board to be removed from or inserted into a live backplane without causing any electrical disruption. This is particularly important in systems that cannot be powered down, such as servers or telecommunications equipment.
• Voltage Range: It operates with a supply voltage range from -9V to -80V, making it versatile for various applications that require a negative supply voltage.
• Adjustable Current Limit: The product features an adjustable overcurrent limit, which helps in protecting the power supply and the load from excessive current that can lead to overheating and potential damage.
• Gate Drive for External N-Channel MOSFET: The controller drives an external N-Channel MOSFET, providing flexibility in the choice of the MOSFET to match specific application requirements.
• Overcurrent Auto-Retry Feature: The LTC4252BCMS-1#PBF includes an auto-retry feature that will attempt to re-enable the load after a fault condition has been removed, which can be crucial for maintaining system uptime.
• Thermal Protection: It incorporates thermal shutdown to protect itself and the system it controls from overheating.
• Compact Package: Housed in a compact MSOP-10 package, the LTC4252BCMS-1#PBF saves precious board space in dense electronic systems.
