LTC1155CS8#TR

Overview

The LTC1155CS8#TR is a dual high-side micropower MOSFET 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 drivers with a maximum quiescent current of 180 uA and an output voltage capability of 18 V. It utilizes an SOIC-8 surface-mount package and functions within a temperature range of 0°C to +70°C.

Feature Summary

• Dual high-side configuration for independent N-channel MOSFET control
• Micropower operation designed for battery-sensitive applications
• Integrated charge pump eliminates external bootstrap components

Applications

• Battery-powered motor control systems
• Portable equipment requiring low standby current
• High-side switching in automotive electronics

Procurement Notes

Verify the specific suffix #TR indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as availability varies by production batch. Ensure the component matches the SOIC-8 footprint and pinout requirements for your PCB layout. Check for obsolescence notices or lifecycle changes from Analog Devices before finalizing procurement plans.

Selection Notes

Select this component when dual high-side driving is required with minimal power consumption. Compare against single-driver alternatives if only one channel is needed. Consider thermal performance within the SOIC-8 package for your specific load conditions. Verify that the 18 V output drive level meets the gate threshold requirements of your target MOSFETs.

Part Context

This part belongs to the LTC1155 series of micropower MOSFET drivers. It shares functional similarities with the LTC1154 single-driver variant but provides dual channels. The CS8 designation identifies the commercial temperature grade and SOIC-8 package style. It is distinct from the CN8 through-hole version.

Replacement Considerations
