LT4254CGN#PBF is listed in the Hot Swap Controllers range at ChipApex. The manufacturer field lists Analog Devices Inc.. Its product description is IC HOT SWAP CTRLR GP 16SSOP. Review the specifications below when checking this part for your BOM.
The LT4254CGN#PBF is a single-channel hot swap voltage controller manufactured by Analog Devices Inc., designed for positive voltage applications. It operates within an input supply range of 10.8 V to 36 V and features an adjustable current limit function. The device draws a typical operating supply current of 1.9 mA and supports surface-mount installation in a 16-lead SSOP package. It functions within a commercial temperature range from 0°C to +70°C, providing essential protection for backplane insertion systems.
Verify the specific suffix '#PBF' confirms lead-free tin-silver-copper plating and RoHS compliance when sourcing. Confirm the 'G' designation indicates the commercial temperature grade suitable for standard industrial environments. Ensure the SSOP-16 footprint matches your PCB layout constraints before finalizing procurement orders.
Select this component for single-rail positive voltage hot swap applications requiring integrated fault protection. Compare against negative voltage controllers if system polarity differs. Consider channel count requirements; this part handles one channel only. Verify that the 36 V maximum input rating aligns with your bus voltage specifications.
This part belongs to the LT4254 series of hot swap controllers. It complements other Analog Devices power management ICs like the LTC4252 for negative rail applications. The SSOP-16 package is common across several Linear Technology legacy parts, ensuring mechanical compatibility with existing designs utilizing similar footprints.
