LTC4444HMS8E#TRPBF

Overview

The LTC4444HMS8E#TRPBF is a high-voltage synchronous N-channel MOSFET gate driver manufactured by Analog Devices. It operates with an input voltage range up to 100 V and supports supply voltages from 7.2 V to 13.5 V. The device features two independent drivers in an MSOP-E-8 package, designed for efficient power management applications requiring robust high-side switching capabilities.

Feature Summary

• Supports high-side N-channel MOSFET driving with input voltages up to 100 V
• Integrates two independent gate drivers for dual-channel control
• Compatible with standard CMOS logic inputs for straightforward interface

Applications

• High-side switching in DC-DC converter topologies
• Synchronous rectification in power supply designs
• Motor control systems requiring isolated or floating gate drive

Procurement Notes

Verify the specific suffix E and TRPBF against official Analog Devices documentation to confirm pinout compatibility and tape-and-reel packaging specifications. Ensure the component meets RoHS standards as indicated in the manufacturer's compliance data before integration into production assemblies.

Selection Notes

Select this component when designing circuits that require driving N-channel MOSFETs at potentials significantly above ground. The dual-driver configuration allows for complementary switching arrangements. Confirm that the operating temperature range and supply voltage limits align with the target system environment.

Part Context

This part belongs to the LTC4444 series of high-voltage gate drivers. It is distinct from low-voltage counterparts and is engineered specifically for applications where the source terminal of the controlled MOSFET floats at high potentials relative to the system ground.

Replacement Considerations

LTC4444IMS8E-5#PBF is a documented tube-packaged variant within the same family. Verify package type differences and ensure electrical parameters match the design requirements before substitution.
