Overview
The LTC4444IMS8E#TRPBF is a high-voltage synchronous N-channel MOSFET driver manufactured by Analog Devices. It integrates two independent gate drivers in an MSOP-8 package, supporting supply voltages from 7.2 V to 13.5 V and handling input signals up to 100 V. The device delivers a peak output current of 3 A with rise and fall times of 80 ns and 50 ns respectively. It operates within a temperature range of -40°C to +125°C and features CMOS logic compatibility with a typical quiescent current of 320 µA.
Feature Summary
- Integrated dual high-side and low-side gate drivers for synchronous rectification applications
- Capable of driving external N-channel MOSFETs with high voltage inputs up to 100 V
- Optimized for fast switching performance with low propagation delay and minimal cross-conduction risk
Applications
- Synchronous buck converters
- High-side power switching circuits
- DC-DC converter control stages
Procurement Notes
Verify the specific suffix E#TRPBF against the manufacturer's latest datasheet to confirm pinout and electrical specifications match your design requirements. Ensure the ordering information aligns with the exact package type and tape-and-reel quantity specified in official documentation before finalizing procurement.
Selection Notes
Select this component when designing circuits requiring isolated or floating gate drive for high-side N-channel MOSFETs. Consider the 100 V input capability and 3 A output drive strength relative to the target MOSFET gate charge. Verify that the operating voltage range of 7.2 V to 13.5 V suits the system power supply constraints.
Part Context
This part belongs to the LTC4444 series of high-voltage MOSFET drivers. It is designed to simplify the implementation of synchronous rectification in power supplies by integrating both high-side and low-side drive functions into a single compact surface-mount package.
Replacement Considerations
Consult Analog Devices documentation for verified alternative part numbers within the same product family or compatible devices with matching electrical characteristics and pin configurations.
