MAX5048CAUT+T

Overview

The MAX5048CAUT+T is a high-speed, 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 features both inverting and non-inverting logic inputs. The device delivers peak output currents of 7.6A sink and 3A source. Typical switching times are 28ns rise and 13ns fall. It is housed in a SOT-23-6 surface-mount package and supports an operating junction temperature range of -40°C to 150°C.

Feature Summary

• Provides simultaneous inverting and non-inverting outputs for flexible control schemes
• Delivers high peak current capability for rapid MOSFET switching
• Operates with low-voltage logic signals down to 0.8V input threshold

Applications

• High-frequency DC-DC converter topologies
• Synchronous rectification circuits
• Motor drive gate driving stages

Procurement Notes

Verify the specific suffix 'C' indicates the extended temperature grade (-40°C to 150°C) compared to standard variants. Confirm the '+T' designation corresponds to tape-and-reel packaging. Ensure compatibility with the target PCB footprint for the SOT-23-6 package before finalizing procurement orders.

Selection Notes

Select this component when high-speed switching with minimal propagation delay is required in a compact form factor. The dual-output configuration simplifies circuit design by eliminating external inverters. Verify that the 7.6A/3A current ratings sufficiently drive the gate capacitance of the intended power MOSFETs at the target switching frequency.

Part Context

This part belongs to the MAX5048 family of high-current MOSFET drivers designed for space-constrained applications. The CAUT variant specifically extends the thermal operating range compared to lower-grade counterparts. It serves as a critical interface between low-power control logic and high-power switching elements in modern power management systems.

Replacement Considerations

The MAX5048BAUT+T is a related variant but typically specifies a lower maximum operating temperature (125°C). Verify if the extended 150°C rating is mandatory for the application environment before substituting.
