MAX5054BATA+T

Overview

The MAX5054BATA+T is a dual, high-speed MOSFET driver IC designed for low-side switching applications. It provides independent inverting and non-inverting outputs with a peak source and sink current of 4A. The device features a fast propagation delay of 20ns and rise/fall times of 20ns. It operates from a supply voltage range of 4V to 15V. The logic input thresholds are defined by VIL at 0.8V and VIH at 2.1V. Packaged in an 8-TDFN (3x3) footprint, it supports N-channel MOSFET gate driving.

Feature Summary

• Dual independent channel configuration supporting both inverting and non-inverting output logic states
• High peak drive capability sourcing and sinking up to 4A per channel
• Fast switching performance characterized by 20ns propagation delay and transition times

Applications

• Low-side N-channel MOSFET gate driving in power conversion circuits
• High-speed digital-to-analog interface buffering for power stages
• General purpose isolated or non-isolated gate drive in motor control systems

Procurement Notes

Verify the specific suffix '+T' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status as indicated by the '+' designation. Ensure the 8-TDFN package dimensions match the PCB footprint design. Check for obsolete lifecycle status if long-term availability is required.

Selection Notes

Select this component when dual independent low-side drive is required with high peak current capability. The 4A output current suits medium-power MOSFETs. Verify that the 4V minimum supply voltage aligns with the system's available rail. Consider the 20ns delay for timing-sensitive synchronous rectification or bridge drive topologies.

Part Context

This part belongs to the Maxim Integrated line of high-speed gate drivers. It is functionally similar to other dual MOSFET drivers but distinguished by its specific 4A current rating and 20ns speed profile. The TDFN package offers thermal efficiency for compact designs compared to larger DIP packages.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other dual 4A MOSFET drivers only after verifying pinout compatibility and electrical specifications against the official datasheet.
