ADP3634ARHZ

Gate Driver Overview

The ADP3634ARHZ 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 4 A per channel. The device features both inverting and non-inverting configurations with rise and fall times of 10 ns. It is housed in an MSOP-8 package and functions reliably across an operating temperature range of -40°C to +85°C.

Gate Driver Feature Summary

• Dual-channel architecture providing independent inverting and non-inverting outputs for flexible control schemes.
• High-speed switching capability with 10 ns rise and fall times to minimize transition losses.
• Robust drive strength delivering 4 A output current to efficiently switch power MOSFETs.

Gate Driver Applications

• Low-side switching in synchronous buck converters
• Motor control circuits requiring fast gate drive signals
• General-purpose power management systems utilizing N-channel MOSFETs

Gate Driver Procurement Notes

Verify the specific suffix ARHZ against official documentation to confirm the MSOP-8 package variant. Confirm availability status as distribution channels may report limited stock or discontinuation. Ensure the selected component matches the required thermal and electrical specifications for the target application environment.

Gate Driver Selection Notes

Select this component when a dual low-side driver with mixed polarity outputs is required. The 4 A drive current supports larger MOSFETs compared to lower-current alternatives. Consider the MSOP-8 footprint constraints and the 9.5 V minimum supply requirement during circuit design.

Gate Driver Part Context

This part belongs to the ADP3634 series of high-speed gate drivers from Analog Devices. It complements other variants like the ADP3634ARDZ (SOIC-8) and ADP3633 family members by offering a compact surface-mount solution for applications needing precise timing and high current drive in a small form factor.

Gate Driver Replacement Considerations

The ADP3634ARDZ serves as a pin-compatible alternative with identical electrical characteristics but utilizes an SOIC-8 package instead of MSOP-8. Verify board space and thermal requirements before substituting.
