LTC1155IN8#PBF

Overview

The LTC1155IN8#PBF is a dual high-side microprocessor MOSFET gate driver manufactured by Analog Devices Inc. It operates within a supply voltage range of 4.5 V to 18 V and supports input voltages up to 22 V. The device features two independent drivers with a maximum dead time of 60 µs and a typical quiescent current of 180 µA. Designed for through-hole mounting, it is housed in an 8-pin PDIP package and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual high-side configuration designed for driving N-channel power MOSFETs
• Integrated deglitching circuitry to minimize output glitches during switching transitions
• Independent control inputs allowing separate timing management for each channel

Applications

• High-side switching in DC-DC converter topologies
• Motor control circuits requiring isolated high-side drive
• Power management systems utilizing microprocessor-controlled load switching

Procurement Notes

Verify the specific suffix #PBF confirms lead-free compliance and RoHS adherence before procurement. Confirm the PDIP-8 package availability matches your PCB footprint requirements. Ensure the supplier provides valid traceability documentation for the Analog Devices manufacturing lot. Cross-reference the datasheet revision date to ensure compatibility with your design specifications.

Selection Notes

Select this component when a dual high-side driver is required for synchronous rectification or load switch applications. The low quiescent current makes it suitable for battery-operated systems where standby power consumption is critical. Verify that the input logic levels are compatible with the controlling microprocessor or FPGA signals.

Part Context

This part belongs to the LTC1155 series of high-speed MOSFET drivers. It serves as a specialized solution for applications requiring precise control of high-side switches without the complexity of discrete bootstrap circuits. The device integrates necessary protection features to ensure reliable operation in noisy industrial environments.

Replacement Considerations

Consult official Analog Devices documentation for verified cross-reference part numbers. Ensure any substitute maintains the same PDIP-8 package and dual high-side functionality.
