MAX5048BAUT+T

Overview

The MAX5048BAUT+T is a single-channel low-side MOSFET gate driver manufactured by Analog Devices Inc. It operates within a supply voltage range of 4V to 12.6V and supports N-channel MOSFETs. The device provides peak output currents of 1.3A source and 7.6A sink. Typical switching times are 82ns rise and 12.5ns fall. Logic thresholds are defined at 0.8V for VIL and 2.4V for VIH. It is housed in a SOT-23-6 package and functions across a junction temperature range of -40°C to 150°C.

Feature Summary

• Provides high peak sink current capability for rapid N-channel MOSFET turn-off
• Supports both inverting and non-inverting logic input configurations
• Operates with low quiescent current consumption during standby

Applications

• Low-side switching in DC-DC converter topologies
• Gate driving for power MOSFETs in motor control circuits
• General purpose switching applications requiring fast turn-off speeds

Procurement Notes

Verify the specific suffix against official manufacturer documentation, as ordering codes may indicate variations in packaging or environmental compliance that do not alter electrical function. Confirm component status, as some variants like the #G16 designation are marked obsolete. Ensure sourcing channels provide valid traceability for RoHS3 compliance requirements.

Selection Notes

Select this component when a compact single-channel driver with asymmetric drive strength is required. The high sink current relative to source current makes it suitable for applications prioritizing fast turn-off times. Verify that the input logic levels align with the specified 0.8V and 2.4V thresholds for reliable operation across the full temperature range.

Part Context

This part belongs to the MAX5048B series of low-side gate drivers from Maxim Integrated, now part of Analog Devices. The series focuses on providing efficient switching performance in small form factors. The BAUT variant specifically utilizes the SOT-23-6 surface-mount package, distinguishing it from other pinout or thermal options within the broader family.

Replacement Considerations

Public records indicate the MAX5048BAUT#G16 variant is obsolete. No direct public substitute part numbers are confirmed for this specific model.
