MAX5063AASA

Overview

The MAX5063AASA is a high-voltage half-bridge MOSFET gate driver manufactured by Analog Devices Inc./Maxim Integrated. It features dual independent drivers configured for high-side and low-side applications, supporting N-channel MOSFETs. The device operates with a supply voltage range of 8V to 12.6V and delivers peak output currents of 2A for both sourcing and sinking. It utilizes an 8-SOIC surface-mount package. Key electrical parameters include rise and fall times of 65ns, with logic input thresholds defined at 0.8V (VIL) and 2V (VIH). The component supports a maximum high-side bootstrap voltage of 125V and functions within a junction temperature range of -40°C to 150°C.

Feature Summary

• Provides non-inverting drive signals for high-side and low-side N-channel MOSFETs in half-bridge configurations.
• Delivers robust 2A peak source and sink current capability to ensure fast switching transitions.
• Supports high-voltage operation with a maximum bootstrap voltage rating of 125V.

Applications

• High-voltage motor control systems requiring precise gate driving.
• Industrial power conversion circuits utilizing half-bridge topologies.
• Inverter stages in AC drives and variable frequency drives.

Procurement Notes

Verify the specific suffix and RoHS compliance status when ordering, as availability may vary between standard and lead-free variants. Confirm that the 8-SOIC footprint matches your PCB layout requirements. Check current stock levels and lifecycle status, as this component may be subject to limited supply or end-of-life notifications from the manufacturer.

Selection Notes

Select this driver for applications requiring high-voltage isolation and strong current drive for N-channel MOSFETs. Ensure the input logic levels are compatible with the specified 0.8V and 2V thresholds. Consider the thermal performance within the 150°C junction limit and verify that the 125V bootstrap rating exceeds the maximum bus voltage in your design.
