LTC4440IS6#TRPBF

Overview

The LTC4440IS6#TRPBF is a high-speed, high-voltage N-channel MOSFET gate driver manufactured by Analog Devices Inc. It operates with a supply voltage range of 6.5 V to 80 V and supports input logic voltages as low as 1.3 V or 1.6 V. The device delivers peak output currents of 2.4 A for both sourcing and sinking. It features typical rise and fall times of 100 ns and 70 ns, respectively. Operating temperatures span from -40°C to +125°C. The component is housed in a compact SOT-23-6 surface-mount package.

Feature Summary

• High-side gate driver configuration designed for driving N-channel MOSFETs
• Capable of operating at bootstrap supply voltages up to 80 V
• Compatible with low-voltage control logic inputs starting at 1.3 V
• Provides robust 2.4 A peak drive current for fast switching

Applications

• High-side power switching in DC-DC converters
• Motor control systems requiring high-voltage gate drive
• Industrial power management circuits
• Automotive electronics applications

Procurement Notes

Verify the specific suffix #TRPBF against official Analog Devices documentation to confirm tape-and-reel packaging and lead-free status. Confirm that the IS6 variant meets the required industrial temperature range specifications for your design. Ensure compatibility with the target PCB footprint for the SOT-23-6 package before finalizing procurement plans.

Selection Notes

Select this component when a single high-side driver is needed for voltages up to 80 V. It is suitable for designs requiring low input threshold compatibility with standard logic levels. Consider the thermal performance within the SOT-23-6 package for your expected duty cycle. Verify that the 2.4 A drive current matches the gate charge requirements of the intended MOSFET load.

Part Context

This part belongs to the LTC4440 family of high-voltage gate drivers. It serves as a specialized power management IC within Analog Devices' portfolio. The device integrates bootstrap functionality to facilitate high-side switching without external level shifters. It is distinct from low-voltage drivers due to its extended supply voltage capability.
