LTC1255CS8#PBF

Overview

The LTC1255CS8#PBF is a dual high-side MOSFET gate driver manufactured by Analog Devices. It operates within a supply voltage range of 4.5V to 24V and is housed in an 8-pin SOIC package. The device provides independent drive outputs for two N-channel power MOSFETs, featuring adjustable dead-time control to prevent shoot-through currents. It includes under-voltage lockout protection and is designed for efficient switching applications requiring precise timing control.

Feature Summary

• Dual independent high-side gate driver outputs
• Adjustable dead-time control mechanism
• Integrated under-voltage lockout protection

Applications

• High-side N-channel MOSFET switching
• DC-DC converter topologies
• Motor control circuits

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the SOIC-8 package dimensions match your PCB footprint requirements. Check current availability status as distribution may vary. Ensure the operating temperature range meets your system specifications before finalizing procurement.

Selection Notes

Select this component when driving dual high-side N-channel MOSFETs with precise dead-time requirements. Consider the 24V maximum supply limit against your system rail. Evaluate the need for integrated UVLO versus external monitoring. Compare pin compatibility if replacing legacy drivers in existing designs.

Part Context

This part belongs to the LTC1255 series of gate drivers from Analog Devices. It is specifically engineered for applications requiring isolated or non-isolated high-side switching. The SOIC-8 package allows for compact surface-mount integration in space-constrained power management designs.

Replacement Considerations

Direct substitutes include other dual high-side drivers with similar pinouts and voltage ratings. Verify functional equivalence regarding dead-time adjustability and output current capability. Ensure package compatibility for direct replacement without PCB redesign.
