LTC4211IMS#TRPBF

The LTC4211IMS#TRPBF is a high-performance hot-swap controller designed to enable safe insertion and removal of circuit boards into live backplanes. This device is particularly suited for advanced mezzanine cards, MicroTCA systems, workstations, servers, and telecom networks.

Key Features:

1. Dual Supply Control: The LTC4211IMS#TRPBF provides independent control of both the 12V main and 3.3V auxiliary supply outputs. This allows for flexible power management and ensures reliable operation of the connected devices.
2. Hot-Swap Capability: With its hot-swap functionality, the LTC4211IMS#TRPBF allows for the safe insertion and removal of circuit boards without disrupting the power supply to the rest of the system. This is achieved through the use of an internal high-side switch driver that controls an external N-channel MOSFET.
3. Overcurrent Protection: The device incorporates two internal current-limiting comparators that provide dual-stage overcurrent circuit breaker protection. This ensures that the system remains protected against potential faults and damage.
4. Programmable Soft-Start: During startup, the LTC4211IMS#TRPBF offers a programmable soft-start feature that limits inrush currents and prevents potential damage to the system. This feature also allows for a gradual increase in power, ensuring a smooth and reliable startup process.
5. Fault Indication and Management: The LTC4211IMS#TRPBF includes FAULT and FILTER pins (for MS packages) that provide additional functionality such as fault indication, automatic retry or latch-off mode, and programmable current-limiting response time. This allows for more sophisticated fault management and system recovery processes.
6. Voltage Monitoring and Control: The FB pin is used to monitor the output power supply voltage and issue indications to the RESET output pin. This ensures that the system can respond appropriately to any changes in the power supply status.
7. Compact Package: The LTC4211IMS#TRPBF is available in a compact 10-MSOP package, making it easy to integrate into existing systems and reducing board space requirements.

Applications:

• Advanced mezzanine cards
• MicroTCA systems
• Workstations and servers
• Telecom networks
• Any application requiring safe hot-swapping of circuit boards into live backplanes

Overall, the LTC4211IMS#TRPBF is a versatile and reliable hot-swap controller that offers advanced power management features and protection against potential faults. Its compact package and wide range of applications make it an ideal choice for designers looking to implement efficient and safe hot-swapping solutions in their electronic systems.
