LTC4444MPMS8E-5#TRPBF

Overview

The LTC4444MPMS8E-5#TRPBF is a high-voltage synchronous N-channel MOSFET driver manufactured by Analog Devices. It integrates high-side and low-side drivers in an MSOP-E-8 package, supporting input voltages up to 100 V. The device operates with a supply voltage range of 7.2 V to 13.5 V and delivers a peak output current of 3 A. Key electrical parameters include a maximum propagation delay of 60 ns, rise time of 80 ns, and fall time of 50 ns. It functions within an industrial temperature range of -55°C to +150°C and consumes 320 µA of quiescent current.

Feature Summary

• Integrates high-side and low-side gate drivers for synchronous rectification applications
• Supports high-voltage inputs up to 100 V with CMOS logic compatibility
• Provides fast switching performance with minimal propagation delay
• Operates reliably across extended military-grade temperature ranges

Applications

• High-voltage synchronous buck converters
• Motor control systems requiring robust gate driving
• Industrial power supplies operating in extreme environments

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when sourcing. Confirm that the MP prefix denotes military-grade qualification requirements for your application environment. Ensure the MSOP-E-8 footprint matches your PCB layout constraints. Cross-reference the datasheet for any recent pinout revisions or thermal pad specifications before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring high-voltage isolation and precise timing control. The 3 A drive capability suits medium-power MOSFETs efficiently. Consider the extended temperature range if ambient conditions exceed standard commercial limits. Evaluate the 7.2 V minimum supply requirement against your available rail voltages to ensure proper operation during startup and transient events.

Part Context

This part belongs to the LTC4444 series of high-voltage MOSFET drivers from Analog Devices. It shares functional similarities with the LTC4444IMS8E-5#PBF but differs in packaging and qualification grade. The MP variant specifically targets ruggedized applications requiring enhanced reliability standards compared to standard commercial counterparts.

Replacement Considerations

The LTC4444IMS8E-5#PBF serves as a commercial-grade alternative with identical electrical specifications but different temperature ratings and packaging options.
