MAX5048AAUT+T

Overview

The MAX5048AAUT+T is a single-channel low-side MOSFET gate driver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4V to 12.6V and supports both inverting and non-inverting logic inputs. The device features peak output currents of 1.3A source and 7.6A sink, with typical rise and fall times of 82ns and 12.5ns respectively. It is housed in a SOT-23-6 surface-mount package and functions reliably across an extended junction temperature range of -40°C to 150°C.

Feature Summary

• Provides high peak sink current capability for rapid MOSFET turn-off
• Supports dual logic input configurations including inverting and non-inverting modes
• Operates over an extended industrial temperature range up to 150°C junction temperature

Applications

• Low-side switching control in DC-DC converters
• Gate driving for N-channel power MOSFETs
• General-purpose power management circuitry

Procurement Notes

Verify the specific suffix 'AAUT' against official manufacturer documentation to confirm exact pinout and electrical characteristics, as variations exist within the MAX5048 family. Ensure the component meets RoHS3 compliance requirements for your assembly process. Confirm availability status directly with authorized distributors, as supply levels may fluctuate. Cross-reference the datasheet revision date to ensure compatibility with your design specifications.

Selection Notes

Select this component when a compact, low-side driver with high peak sink current is required for efficient power switching. The SOT-23-6 package offers space savings compared to larger footprints. Consider the 12.6V maximum supply limit and the specific rise/fall time trade-offs inherent to the technology. Verify that the logic voltage thresholds align with your microcontroller or controller IC outputs.
