Product Overview: LTC4231CUD-2#PBF

The LTC4231CUD-2#PBF from Linear Technology is a high-performance Hot Swap™ controller that allows a board to be safely inserted and removed from a live backplane. This integrated circuit provides intelligent control of the power to board level components, ensuring both the board and the backplane are protected from the potential damage caused by short circuits, overcurrent, overvoltage, and other fault conditions.

Key Features

• Adjustable Supply Voltage: The LTC4231 operates over a wide supply voltage range, accommodating various system requirements and ensuring versatility across different applications.
• Programmable Current Limit: Users can set the overcurrent threshold to match the needs of their specific application, providing precise control over the power distribution system.
• Fast Overcurrent Protection: The device responds quickly to overcurrent conditions, minimizing the risk of damage to sensitive components on the board.
• Multi-Function Timer: An onboard timer provides control over fault detection and power-up sequencing, enhancing system reliability.
• Under Voltage Lockout (UVLO): This feature ensures that the controller remains off if the supply voltage is too low, preventing malfunctioning of the system due to insufficient power.
• Low Quiescent Current: The LTC4231CUD-2#PBF boasts a low quiescent current, which is ideal for power-sensitive applications.
• Compact Package: Housed in a 12-pin QFN package, the LTC4231CUD-2#PBF is designed for space-constrained applications.
