ADP3631ARMZ-R7

Gate Driver Overview

The ADP3631ARMZ-R7 is a high-speed, dual low-side MOSFET gate driver manufactured by Analog Devices Inc. It operates within a supply voltage range of 9.5 V to 18 V and delivers a peak output current of 2 A per channel. The device features propagation delays with a maximum of 35 ns, rise times of 14 ns, and fall times of 25 ns. Designed for surface-mount installation in an MSOP-8 package, it functions reliably across an operating temperature range of -40°C to +85°C while consuming only 1.2 mA of quiescent supply current.

Gate Driver Feature Summary

• Dual-channel architecture providing independent control for two low-side MOSFETs
• High-speed switching capability with nanosecond-level rise and fall times
• Low quiescent current consumption for efficient power management
• Robust output stage capable of sourcing and sinking 2 A drive current

Gate Driver Applications

• Synchronous buck converter circuits requiring fast switching speeds
• Motor drive systems utilizing low-side N-channel MOSFETs
• Power supply designs needing isolated or non-isolated gate driving
• Industrial automation equipment with high-frequency power stages

Gate Driver Procurement Notes

Verify the specific suffix R7 indicates reel packaging when ordering. Confirm the MSOP-8 package type matches your PCB footprint requirements. Ensure the 9.5 V minimum supply voltage aligns with your system's logic levels. Check RoHS compliance documentation if environmental regulations apply to your manufacturing process.

Gate Driver Selection Notes

Select this component when dual low-side driving is required without inversion. Compare against the ADP3630 if non-inverting outputs are needed instead. Consider the 2 A drive strength sufficient for your MOSFET gate charge requirements. Verify that the 18 V maximum supply voltage accommodates your highest expected bus voltage conditions safely.

Gate Driver Part Context

This part belongs to the ADP3630/ADP3631 family of high-speed gate drivers from Analog Devices. These devices are designed to replace discrete driver solutions in compact power electronics applications. The ADP3631 specifically offers dual low-side outputs, distinguishing it from single-channel or inverting variants within the same product line.

Gate Driver Replacement Considerations

The ADP3630ARMZ-R7 serves as a functional substitute if non-inverting outputs are acceptable. Both parts share identical pinouts, packages, and electrical characteristics except for signal inversion. Verify that the application circuitry supports the logical difference between inverting and non-inverting configurations before swapping.
