LT1161ISW#PBF

Overview

The LT1161ISW#PBF is a quad high-side gate driver manufactured by Analog Devices Inc. It enables the use of low-cost N-channel power MOSFETs for high-side switching applications. The device features four independent switch channels, each containing a completely self-contained charge pump to fully enhance an N-channel MOSFET switch with no external components. It operates within an input voltage range of 8V to 48V and is housed in a 20-pin SOIC W package.

Feature Summary

Four independent switch channels with self-contained charge pumps
Enables low-cost N-channel MOSFET usage for high-side switching
No external components required for full enhancement

Applications

High-side switching applications
Industrial motor control systems
Automotive power distribution networks

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS status. Confirm the ISW variant meets automotive temperature specifications if required. Check current availability as supply may be limited. Ensure the 20-pin SOIC W package matches the PCB footprint design. Validate input voltage ranges against system requirements before integration.

Selection Notes

Select this component when driving multiple N-channel MOSFETs in a high-side configuration. The integrated charge pumps eliminate the need for external bootstrap capacitors or drivers. Consider the 8V to 48V input range for compatibility with standard industrial and automotive bus voltages. Evaluate thermal performance within the SOIC W package for the expected load currents.

Part Context

This part belongs to the LT1161 family of protected quad high-side MOSFET drivers. It shares functional similarities with other high-side drivers but distinguishes itself through integrated charge pumps and protection features. The ISW designation specifies the industrial temperature range and wide-body SOIC packaging, differentiating it from commercial variants.
