LTC4224CMS-2#PBF

Hot Swap Controllers Overview

The LTC4224CMS-2#PBF is a dual low voltage Hot Swap controller manufactured by Analog Devices Inc. It enables safe insertion and removal of boards from live backplanes by controlling two independent power supplies. The device operates within a supply voltage range of 2.9 V to 36 V and draws a typical operating supply current of 1.4 mA. It is housed in a compact 10-TFSOP or 10-MSOP package with a maximum body width of 3.00 mm. The component supports an extended commercial temperature range from 0°C to 70°C.

Hot Swap Controllers Feature Summary

• Dual channel control for managing two separate power supplies during hot swap events
• Integrated protection against overvoltage, undervoltage, and overcurrent conditions
• Compact surface-mount packaging suitable for space-constrained designs

Hot Swap Controllers Applications

• Safe insertion and removal of circuit boards from live backplanes
• Dual power supply management in telecommunications equipment
• Industrial control systems requiring redundant power inputs

Hot Swap Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free tin plating and RoHS compliance when ordering. Confirm the package variant matches the required footprint, as MSOP and TFSOP pinouts may differ. Check for recent Product Change Notices (PCN) regarding material or process updates that could affect compatibility. Ensure the operating temperature range meets the environmental requirements of the final assembly.

Hot Swap Controllers Selection Notes

Select this component when dual-channel hot swap protection is required for low-voltage applications. Compare input voltage ranges and current limits against system specifications to ensure adequate headroom. Evaluate the thermal performance within the 10-lead MSOP package for the expected load conditions. Verify that the control logic interfaces are compatible with the target microcontroller or FPGA signals.

Hot Swap Controllers Part Context

This part belongs to the LTC4224 family of dual low voltage Hot Swap controllers. The -2 suffix typically denotes specific internal threshold settings or feature variations compared to other variants like the LTC4224-1. The family is designed for applications requiring robust power sequencing and protection in compact form factors.

Hot Swap Controllers Replacement Considerations

Direct substitutes include other parts within the LTC4224 series, such as the LTC4224CMS-1#PBF, provided the electrical thresholds match the design requirements. Cross-reference pinouts and control logic polarity before substitution.
