LT1161CSW#TRPBF

Overview

The LT1161CSW#TRPBF 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 with a self-contained charge pump to fully enhance N-channel MOSFET switches without external components. It operates within an input voltage range of up to 60 V and a supply voltage range of 8 V to 48 V. The unit is housed in a 20-pin SOIC-W package and supports a maximum deadtime of 200 us.

Feature Summary

• Four independent high-side switch channels with integrated charge pumps
• Protective overvoltage shutdown functionality
• Automotive-grade design suitable for solenoid drivers

Applications

• Automotive solenoid driving
• Industrial switching applications
• High-side N-channel MOSFET control

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official documentation. Ensure the component matches the 20-pin SOIC-W form factor required by the target PCB layout. Cross-reference the manufacturer part number directly with Analog Devices to avoid counterfeit risks.

Selection Notes

Select this component for designs requiring isolated high-side drive for multiple N-channel MOSFETs. The integrated charge pump simplifies circuit design by eliminating external bootstrap capacitors. Consider the automotive qualification if operating in vehicle environments. Verify that the 48 V maximum supply voltage aligns with the system power rails.

Part Context

This part belongs to the LT1161 series of protected quad high-side gate drivers. It is functionally similar to the LT1161CN but differs in package type and reel configuration. The CSW variant specifically denotes the wide-body SOIC package optimized for thermal performance and automotive reliability standards.

Replacement Considerations

LT1161CN#PBF serves as a pin-compatible alternative in a PDIP-20 package.
