MAX5078BATT-T

Overview

The MAX5078BATT-T is a low-side MOSFET gate driver manufactured by Analog Devices Inc./Maxim Integrated. It features a single channel with both inverting and non-inverting inputs, designed for driving N-channel power MOSFETs. The device operates within a supply voltage range of 4V to 15V and supports peak output currents of 4A source and 4A sink. Typical switching characteristics include an 85ns rise time and a 75ns fall time. Logic input thresholds are defined at 0.8V for VIL and 2.1V for VIH. The component is housed in a 6-TDFN (3x3) package with exposed pad and functions across a junction temperature range of -40°C to 150°C.

Feature Summary

• Provides dual logic input options with dedicated inverting and non-inverting channels for flexible control signal integration.
• Delivers symmetrical high-current drive capability to ensure rapid switching transitions for power MOSFETs.
• Incorporates robust protection mechanisms including under-voltage lockout to maintain safe operation during power fluctuations.

Applications

• Synchronous buck converter topologies
• Motor control systems requiring low-side switching
• DC-DC converter power stages

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when sourcing components. Confirm that the part number corresponds to the standard MAX5078BATT+T variant rather than the AATT version which may have different electrical specifications. Ensure compatibility with the required 6-TDFN footprint and verify RoHS compliance status for the specific manufacturing lot prior to procurement.

Selection Notes

Select this component for applications requiring a compact low-side driver with simultaneous inverting and non-inverting outputs. The 4A peak current rating suits moderate-power MOSFET switching needs. Consider the 6-TDFN package size for space-constrained designs. Evaluate the 4V minimum supply voltage against system rail availability. Compare thermal performance requirements against the 150°C maximum junction temperature limit for high-temperature environments.

Part Context

The MAX5078 series belongs to Maxim Integrated's portfolio of low-side gate drivers designed for efficient power management solutions. This specific model variant utilizes a TDFN package to minimize board space while maintaining thermal efficiency. It serves as a critical interface between low-voltage logic controllers and high-power switching elements in modern electronic power conversion circuits.
