ADP3635ARDZ-RL

Gate Driver Overview

The ADP3635ARDZ-RL is a high-speed, dual low-side MOSFET gate driver manufactured by Analog Devices. It provides independent drive for two N-channel power MOSFETs with a peak output current of 4 A. The device operates on a supply voltage range of 9.5 V to 18 V and features a typical rise time of 14 ns. It includes integrated thermal protection with warning and shutdown functions, an under-voltage lockout (UVLO) with hysteresis, and a precision threshold shutdown comparator. The component is housed in an SOIC-8 package and supports surface mount installation.

Gate Driver Feature Summary

• Dual channel architecture driving independent N-channel MOSFETs
• Integrated over-temperature warning and shutdown protection
• Precision threshold shutdown comparator for system redundancy
• Under-voltage lockout with hysteresis for safe startup

Gate Driver Applications

• AC-DC switch mode power supplies
• DC-DC power conversion systems
• Synchronous rectifier circuits
• Motor drive applications

Gate Driver Procurement Notes

Verify the specific suffix RL indicates reel packaging when sourcing. Confirm RoHS compliance status through official documentation. Check for moisture sensitivity level requirements during storage and handling. Ensure the SOIC-8 package matches the target PCB footprint. Validate that the 9.5 V minimum supply voltage aligns with the system design.

Gate Driver Selection Notes

Select this component for designs requiring high-speed switching of dual N-channel MOSFETs. The 4 A drive current supports moderate load requirements. The 9.5 V to 18 V supply range suits standard logic-level control interfaces. Integrated thermal management reduces external component count. Verify compatibility with the intended PWM controller input levels.

Gate Driver Part Context

This part belongs to the ADP362x/ADP363x series of high-current, dual-channel drivers. The series shares industrial standard pinouts while offering enhanced speed and reliability. It complements other Analog Devices power management solutions by providing robust gate drive capabilities for synchronous rectification and motor control topologies.

Gate Driver Replacement Considerations

Cross-reference with ADP3625ARDZ-RL for similar functionality with a different supply voltage range. Verify pinout compatibility before substitution. Ensure thermal performance meets application requirements.
