Product Overview: LTC4252-1CMS#PBF

The LTC4252-1CMS#PBF is a high-performance negative voltage Hot Swap™ controller from Analog Devices Inc., designed to allow a board to be safely inserted and removed from a live backplane. This integrated circuit (IC) provides intelligent control of the power supply to a load during insertion (hot swapping) by limiting the inrush current to prevent glitches on the power supply that can reset other boards in the system.

Key Features

• Voltage Range: This device operates with a supply voltage range suited for negative voltage applications, ensuring compatibility with a variety of systems.
• Adjustable Current Limit: The LTC4252-1CMS#PBF allows precise setting of the current limit threshold via an external resistor, providing flexibility to match the requirements of the specific application.
• Overcurrent Protection: It features robust overcurrent protection to safeguard the system against short-circuits or excessive load conditions.
• High-Speed Circuit Breaker: The fast response time of the integrated circuit breaker minimizes the risk of damage due to overcurrent events.
• Gate Drive for External N-Channel MOSFET: The controller provides a gate drive for an external N-Channel MOSFET, enabling efficient power control and distribution.
• Power Good Output: A 'power good' output signal is available, which can be used to enable a downstream converter or notify the system that the power is stable and within specifications.
• Compact Package: The LTC4252-1CMS#PBF comes in a compact MSOP-10 package, ideal for space-constrained applications.

Applications

The LTC4252-1CMS#PBF is suitable for a wide range of applications, including but not limited to server hot swap applications, negative supply control in telecom systems, and industrial systems where safe insertion and removal of electronic components are required. Its robust feature set ensures reliable operation in harsh environments, making it a preferred choice for system designers looking for a negative voltage Hot Swap controller solution.
