MAX5063DASA+

Overview

The MAX5063DASA+ is a high-voltage half-bridge MOSFET gate driver manufactured by Analog Devices Inc./Maxim Integrated. It features dual independent drivers capable of sourcing and sinking 2A peak output current. The device operates with a supply voltage range of 8V to 12.6V and supports bootstrap voltages up to 125V. It utilizes an 8-SOIC surface-mount package. Key timing parameters include rise and fall times of 65ns, with maximum on and off delays of 40ns. The component functions with non-inverting logic inputs and maintains low quiescent current.

Feature Summary

• Supports high-side switching with bootstrap operation up to 125V for driving N-channel MOSFETs in half-bridge configurations.

Applications

• High-voltage power conversion circuits
• Motor control systems requiring half-bridge topologies

Procurement Notes

Verify the specific suffix 'D' against official datasheets to confirm exact electrical characteristics and pinout compatibility. Confirm RoHS compliance status and lead time restrictions due to potential limited availability or end-of-life status. Ensure the SOIC-8 footprint matches the target PCB design before procurement.

Selection Notes

Select this component when a robust half-bridge driver is required for high-voltage N-channel MOSFETs. The 2A drive strength ensures fast switching transitions suitable for efficient power stages. Consider the 125V bootstrap capability as a primary differentiator for high-side applications compared to lower-voltage alternatives.
