LTC1255IS8#PBF

Overview

The LTC1255IS8#PBF 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 delivers an output current capability of 23 uA and features a maximum dead time of 60 us. It functions at a quiescent supply current of 600 uA with an output voltage of 10.5 V. The component is rated for operation between -40°C and +70°C and is housed in an 8-pin PDIP package.

Feature Summary

• Dual-channel architecture designed specifically for driving high-side N-channel power MOSFETs
• Inherent dead-time control mechanism prevents cross-conduction in half-bridge configurations
• Integrated bootstrap diode simplifies external circuit design and reduces component count
• Robust input threshold compatibility ensures reliable switching across varying logic levels

Applications

• Synchronous rectification in DC-DC converter topologies
• Motor control systems requiring precise high-side switching
• Power supply circuits utilizing half-bridge or full-bridge architectures

Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm pinout and electrical characteristics match the required application. Ensure that the PDIP-8 package dimensions align with the target PCB footprint. Confirm compliance with relevant environmental standards such as RoHS before finalizing procurement decisions.

Selection Notes

Select this component when a dedicated dual high-side driver is necessary for synchronous applications. Consider the 23 uA output current limit and 600 uA quiescent current for power-sensitive designs. Evaluate the 9 V minimum supply requirement against available system rails. Assess thermal performance within the specified -40°C to +70°C operating range for the intended environment.
