LTC4444EMS8E-5#TRPBF

Overview

The LTC4444EMS8E-5#TRPBF is a high-voltage synchronous N-channel MOSFET gate driver manufactured by Analog Devices Inc. It integrates two drivers in an MSOP-8 package, supporting input voltages up to 100 V and operating supply voltages from 7.2 V to 13.5 V. The device delivers 3 A output current with rise and fall times of 80 ns and 50 ns respectively. It features CMOS logic inputs, operates between -40°C and +125°C, and consumes 350 µA quiescent current.

Feature Summary

• Integrates high-side and low-side drivers for synchronous rectification
• Supports high-voltage inputs up to 100 V
• Provides independent three-state PWM input logic
• Operates with standard CMOS logic levels

Applications

• Synchronous rectifier control in DC-DC converters
• High-voltage half-bridge configurations

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the E-grade temperature range matches application requirements. Check availability status as distribution may vary. Ensure the MSOP-8 footprint aligns with PCB design constraints before procurement.

Selection Notes

Select this component for applications requiring high-voltage isolation and synchronous rectification. Compare against the IMS8 variant if industrial temperature ratings are sufficient. Verify that the 100 V input rating exceeds the maximum bus voltage. Consider the 3 A peak drive current capability relative to the target MOSFET gate charge requirements.

Part Context

This part belongs to the LTC4444 series of high-voltage MOSFET drivers. It is designed for efficient power conversion where traditional diodes cause significant losses. The device simplifies design by integrating bootstrap and level-shifting functions typically required in high-side driving applications.
