ADP3624ARHZ-RL

Gate Driver Overview

The ADP3624ARHZ-RL is a high-speed, dual-channel MOSFET gate driver manufactured by Analog Devices Inc. It features two independent outputs capable of sourcing and sinking 4 A of current to drive N-channel power MOSFETs. The device operates with a supply voltage range of 4.5 V to 18 V and supports both inverting and non-inverting input configurations. It utilizes an 8-lead MSOP package and includes thermal protection mechanisms such as overtemperature warning and shutdown. Typical rise and fall times are 10 ns under a 2.2 nF load, with matched propagation delays between channels.

Gate Driver Feature Summary

• Dual high-current outputs for independent N-channel MOSFET control
• Integrated thermal protection with warning and shutdown thresholds
• Fast switching performance with 10 ns typical transition times
• Wide supply voltage compatibility for diverse power architectures

Gate Driver Applications

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

Gate Driver Procurement Notes

Verify the specific suffix ARHZ against official Analog Devices documentation to confirm the MSOP-8 package variant. Ensure the RL designation matches the required reel packaging quantity. Cross-reference the operating temperature range and UVLO settings with system requirements before integration.

Gate Driver Selection Notes

Select this component when high-speed switching and precise thermal management are critical for dual-MOSFET topologies. The 4 A drive capability suits medium-power applications requiring fast transitions. Consider the MSOP footprint constraints and the 4.5 V minimum supply requirement relative to the controller logic levels.

Gate Driver Part Context

Part of the ADP362x/ADP363x family of high-current, dual high-speed drivers designed for improved system reliability. The series maintains industry-standard footprints while enhancing switching speed. The ADP3624 specifically targets lower supply voltage ranges compared to the ADP363x variants, offering flexibility in low-voltage power stages.
