ADP3633ARHZ-RL

Gate Driver Overview

The ADP3633ARHZ-RL is a high-speed, dual-channel MOSFET gate driver from Analog Devices. It provides 4 A output current with 14 ns rise time. Operating voltage ranges from 9.5 V to 18 V. The device features inverting logic and operates between -40°C and +85°C. It includes UVLO, thermal warning, and shutdown protection. Packaged in MSOP-8.

Gate Driver Feature Summary

• Dual-channel architecture for independent N-channel MOSFET control
• Integrated overtemperature warning and shutdown protection
• Precision threshold shutdown comparator for system redundancy
• UVLO with hysteresis for safe startup and shutdown

Gate Driver Applications

• AC-to-DC switch mode power supplies
• DC-to-DC power supplies
• Synchronous rectification circuits
• Motor drive systems

Gate Driver Procurement Notes

Verify the specific suffix ARHZ-RL against the official datasheet to confirm package type and reel quantity. Ensure compatibility with the 9.5 V to 18 V supply range requirement. Confirm that the inverting input configuration matches the controller interface. Check for RoHS compliance documentation prior to integration.

Gate Driver Selection Notes

Select this component when driving two independent N-channel MOSFETs requiring high speed and 4 A peak current. The 9.5 V minimum supply voltage distinguishes it from the 4.5 V variants. The MSOP-8 package offers a compact footprint suitable for space-constrained designs while maintaining thermal performance through enhanced PCB mounting.

Gate Driver Part Context

This part belongs to the ADP362x/ADP363x family of high-current, dual high-speed drivers. The ADP363x series specifically requires a higher supply voltage range (9.5 V to 18 V) compared to the ADP362x series. The family shares industry-standard pinouts but adds improved switching performance and reliability features like thermal protection.

Gate Driver Replacement Considerations

The ADP3623ARHZ-RL serves as a functional substitute within the same family, offering identical pinout and features but supporting a lower supply voltage range starting at 4.5 V instead of 9.5 V.
