Overview
The LTC4442EMS8E#PBF is a high-speed synchronous N-channel MOSFET gate driver manufactured by Analog Devices Inc. It integrates two independent drivers in an 8-lead MSOP package with exposed pad. The device supports input voltages up to 38 V and operates on supply rails between 6 V and 9.5 V. It delivers a peak output current of 5 A with propagation delays of 20 ns, rise times of 12 ns, and fall times of 8 ns. Operating temperatures range from -40°C to +85°C.
Feature Summary
- Integrates high-side and low-side drivers for synchronous rectification applications
- Supports high input voltage operation up to 38 V
- Provides fast switching performance with nanosecond-level rise and fall times
Applications
- Synchronous buck converter topologies
- High-side and low-side MOSFET control circuits
- DC-DC power management systems requiring fast switching
Procurement Notes
Verify the specific suffix #PBF indicates lead-free compliance and RoHS standards before procurement. Confirm the MSOP-E-8 package dimensions match your PCB footprint requirements. Check official Analog Devices documentation for the latest manufacturing status and availability constraints as distribution channels may vary.
Selection Notes
Select this component when designing synchronous rectifier stages requiring high input voltage tolerance up to 38 V. Ensure the operating supply voltage remains within the 6 V to 9.5 V range. Consider the 5 A output drive capability for driving moderate-sized N-channel MOSFETs efficiently at high frequencies.
Part Context
This part belongs to the LTC4442 series of high-speed MOSFET gate drivers. It is designed specifically for applications requiring isolated or non-isolated control of synchronous rectifiers. The MSOP-E-8 package provides thermal performance benefits through the exposed pad design.
Replacement Considerations
Consult official Analog Devices documentation for verified cross-reference part numbers. Ensure any substitute maintains compatible input voltage ranges, drive currents, and package specifications.
