LTC4216IDE

Hot Swap Controllers Overview

The LTC4216IDE is a positive low voltage Hot Swap controller designed for safe board insertion and removal from live backplanes. It controls load voltages ranging from 0V to 6V and isolates severe faults with instantaneous analog current limiting. An internal high side switch driver controls an external N-channel MOSFET gate. The device features adjustable soft-start to limit inrush current during startup with large load capacitors. It provides dual-level overcurrent protection via an electronic circuit breaker with adjustable response time. No external gate capacitor is required for loop compensation.

Hot Swap Controllers Feature Summary

• Instantaneous analog current limiting for severe fault isolation
• Adjustable soft-start limits inrush current at startup
• Dual-level overcurrent protection with adjustable response time
• Internal high side switch driver for external N-channel MOSFET

Hot Swap Controllers Applications

• Low voltage hot swap applications
• Board insertion into live backplanes
• 1.8V power supply systems

Hot Swap Controllers Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm the specific suffix matches the requested package and temperature range. Check datasheet revisions for any updates to electrical characteristics or pinout configurations before finalizing procurement plans.

Hot Swap Controllers Selection Notes

Select this controller for applications requiring precise control of load voltages between 0V and 6V. Ensure the external N-channel MOSFET ratings exceed the maximum expected current and voltage stresses. Verify that the adjustable current limit and soft-start parameters align with the system's thermal and power delivery requirements.

Hot Swap Controllers Part Context

This component belongs to the LTC4216 family of hot swap controllers, specifically engineered for low voltage environments. It addresses the need for robust power management in systems where boards must be safely connected to active power rails without causing voltage sags or damage.

Hot Swap Controllers Replacement Considerations

Consult official Analog Devices documentation for cross-reference information. Verify compatibility of pinouts and electrical specifications if substituting with other hot swap controllers from different manufacturers.
