LTC4444IMS8E-5#TRPBF

Overview

The LTC4444IMS8E-5#TRPBF is a dual high-side and low-side MOSFET gate driver manufactured by Analog Devices Inc. It operates within a supply voltage range of 7.2 V to 13.5 V and supports input voltages up to 100 V. The device provides peak output currents of 3 A for both sourcing and sinking. It features typical rise and fall times of 80 ns and 50 ns, respectively, with a maximum propagation delay of 60 ns. Designed for surface mount installation in an MSOP-E-8 package, it functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Dual-channel configuration providing independent high-side and low-side drive capabilities
• Capable of driving N-channel MOSFETs with high peak output current
• Supports high-voltage inputs suitable for bridge topologies
• CMOS logic interface compatible with standard control signals

Applications

• Synchronous buck converter circuits
• Half-bridge and full-bridge power stages
• Motor driver interfaces
• Isolated DC-DC converter gate control

Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm the E-5 designation matches the required voltage threshold or logic compatibility for your application. Ensure the MSOP-E-8 thermal pad is properly connected to the PCB ground plane for adequate heat dissipation during operation.

Selection Notes

Select this component when a compact dual-driver solution is needed for synchronous rectification or bridge applications. The wide operating temperature range makes it suitable for industrial environments. Consider the 3 A output capability against the gate charge requirements of the target MOSFETs to ensure sufficient switching speed without excessive drive losses.

Part Context

This part belongs to the LTC4444 series of gate drivers from Analog Devices. It is designed to replace discrete driver solutions in space-constrained designs. The IMS8E package offers a small footprint while maintaining robust thermal performance through the exposed pad.

Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio that offer similar current drive and voltage ratings. Verify that any substitute maintains the same MSOP-E-8 package dimensions and thermal characteristics.
