LTC7061IMSE#WTRPBF

Overview

The LTC7061IMSE#WTRPBF is a dual high-side gate driver manufactured by Analog Devices Inc., designed to drive two N-channel MOSFETs in a half-bridge configuration with supply voltages up to 100V. It operates within a power supply range of 5V to 14V and supports an output current of 300µA. The device features adjustable dead time, with propagation delays specified at 14ns and 18ns. It includes comprehensive protection mechanisms such as under-voltage lockout for both high and low sides, overvoltage protection, and overtemperature shutdown. The component is housed in a 12-lead MSOP package with an exposed pad and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Drives two N-channel MOSFETs in a half-bridge configuration with high transient immunity
• Provides independent control for high-side and low-side drivers with different ground references
• Includes integrated protection against under-voltage, overvoltage, and overtemperature conditions

Applications

• High-voltage motor control systems
• Industrial power switching applications
• Inverter circuits requiring isolated or floating gate drive

Procurement Notes

Verify the specific suffix WTRPBF indicates tape-and-reel packaging when sourcing. Confirm the IMSE variant meets industrial temperature requirements (-40°C to +125°C). Ensure compatibility with the target MOSFET gate charge specifications given the 300µA output current limit. Check for RoHS compliance documentation corresponding to the PBF suffix designation.

Selection Notes

Select this component when driving high-side N-channel MOSFETs in 100V half-bridge topologies. It is suitable for applications requiring precise dead-time control and robust protection against fault conditions. Consider the limited output current capability for smaller MOSFETs or lower switching frequency requirements. Evaluate the MSOP-12 package constraints for thermal management and PCB layout space.

Part Context

This part belongs to the LTC7061 family of dual high-side gate drivers from Analog Devices. It shares core functionality with variants like the LTC7061EMSE#PBF but differs in packaging (MSOP vs. MSOP-12 EP) and reel configuration. The IMSE designation specifies the industrial temperature grade, distinguishing it from commercial grade options within the same functional family.

Replacement Considerations

Direct substitutes include other parts from the LTC7061 series such as the LTC7061EMSE#PBF, provided the package and temperature grade differences are acceptable. Verify pinout compatibility and electrical parameters before substitution.
