LTC4444MPMS8E#PBF

Overview

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

Feature Summary

• Integrated dual-channel driver architecture providing both high-side and low-side gate drive capabilities for synchronous rectification applications.
• Capable of driving external N-channel MOSFETs with high input voltage tolerance, eliminating the need for isolated power supplies for the high-side driver.
• Designed for robust performance in harsh environments with an extended operating temperature range suitable for military and industrial standards.

Applications

• High-voltage synchronous rectification in DC-DC converters
• Motor control systems requiring precise gate driving
• Industrial power management modules

Procurement Notes

Verify availability status as this component may be subject to limited supply or factory special order constraints. Confirm that the specific suffix E-5 matches the required temperature grade and pinout configuration for your design. Ensure compliance with RoHS directives and check for any recent product change notices affecting lead times or manufacturing locations before finalizing procurement plans.

Selection Notes

Select this part when designing circuits requiring high-side drive for N-channel MOSFETs without isolated supplies. The wide input voltage range accommodates various bus voltages. Consider the thermal performance in the MSOP-8 package for your PCB layout. Verify that the 3A peak current meets the gate charge requirements of your selected MOSFETs at the target switching frequency.

Part Context

This component belongs to the LTC4444 series of high-voltage MOSFET drivers. It is distinct from standard logic-level drivers due to its ability to handle common-mode voltages up to 100V. The MP suffix indicates a military-grade temperature range variant compared to commercial versions like the IMS8E.

Replacement Considerations

LTC4444IMS8E-5#PBF is a commercial grade alternative with a lower temperature range (-40°C to +125°C). Verify if the extended temperature capability of the MP version is strictly necessary for your application environment.
