LTC4214-2IMS#PBF

Hot Swap Controllers Overview

The LTC4214-2IMS#PBF is a single-channel negative voltage Hot Swap controller manufactured by Analog Devices Inc. It manages power delivery and protection for supplies ranging from near zero to -16V. The device features an adjustable current limit and multifunction timer for start-up delay and circuit breaker response. It operates within a supply voltage range of 2.7V to 36V, with a quiescent current of 4µA. The component supports an operating temperature range from -40°C to +85°C and is housed in a 12-lead MSOP package.

Hot Swap Controllers Feature Summary

• Enables safe insertion and removal of boards from live backplanes handling negative voltages
• Provides adjustable current limiting to protect against overcurrent conditions
• Integrates multifunction timers for controlled start-up sequencing and fault response

Hot Swap Controllers Applications

• Negative voltage hot swap control in telecommunications equipment
• Server and storage system backplane power management
• Industrial control systems requiring safe module replacement under load

Hot Swap Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the IMS package variant matches your PCB footprint requirements. Ensure the negative voltage rating aligns with your system's rail specifications. Check for any recent product change notifications that may affect pinout or electrical characteristics.

Hot Swap Controllers Selection Notes

Select this component when managing negative rails between 0V and -16V. It is suitable for applications requiring precise current limiting and controlled ramp-up times. Consider the MSOP-12 package size for space-constrained designs. Verify compatibility with the system's ground reference and logic levels for proper operation.

Hot Swap Controllers Part Context

This part belongs to the LTC4214 series of negative voltage Hot Swap controllers. It is designed specifically for protecting circuits during board insertion into live backplanes. The series offers robust protection features including current limiting and thermal shutdown for reliable operation in demanding environments.

Hot Swap Controllers Replacement Considerations

Direct substitutes include other Analog Devices negative Hot Swap controllers such as the LTC4215 series. Verify voltage ranges and package compatibility when considering alternatives. Cross-reference pinouts and timing parameters to ensure functional equivalence.
