LTC1255IS8#TRPBF

Overview

The LTC1255IS8#TRPBF is a dual high-side MOSFET gate driver manufactured by Analog Devices Inc. It operates within a supply voltage range of 9 V to 24 V and supports input voltages up to 30 V. The device provides two independent outputs with a maximum dead time of 60 µs to prevent shoot-through in bridge configurations. Designed for surface-mount installation, it utilizes an 8-lead SOIC package. The component functions as a power management IC suitable for driving external N-channel MOSFETs in applications requiring reliable high-side switching control.

Feature Summary

• Dual channel architecture providing independent high-side drive capabilities
• Integrated dead-time generation to ensure safe bridge operation
• Input tolerance exceeding supply voltage for direct logic interfacing

Applications

• High-side N-channel MOSFET switching circuits
• DC-DC converter topologies requiring isolated or floating gate drive
• Motor control systems utilizing half-bridge configurations

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when sourcing. Confirm that the IS8 variant corresponds to the industrial temperature range and SOIC-8 package dimensions required for your PCB layout. Ensure compatibility with the 9 V to 24 V supply rails specified in the official datasheet before finalizing procurement orders.

Selection Notes

Select this component when a dual high-side driver is required for N-channel MOSFETs. It is appropriate for designs needing integrated dead-time control to simplify timing requirements. Consider the 8-lead SOIC package constraints and the 24 V maximum supply limit during circuit planning. Verify that the input signal levels align with the device's common-mode rejection capabilities.

Part Context

This part belongs to the LTC1255 family of high-side gate drivers from Analog Devices. It serves as a specialized interface between low-voltage logic controllers and high-power switching elements. The series is designed to provide robust performance in power conversion environments where precise timing and reliability are critical for system stability.

Replacement Considerations

Consult official Analog Devices documentation for verified cross-reference part numbers. Ensure any substitute maintains identical pinout, voltage ratings, and package dimensions to guarantee mechanical and electrical compatibility without redesigning the host circuit.
