Analog Devices Inc./Maxim Integrated MAX5054BATA+T

Overview

The MAX5054BATA+T from Maxim Integrated is a dual high-speed MOSFET driver with TTL logic inputs, delivering 4A peak source/sink current per channel and 20ns typical propagation delay while driving 5000pF loads. It operates from 4V to 15V, features matched delays between inverting/noninverting inputs and across channels, and is qualified for automotive applications from −40°C to +125°C.

For engineers reviewing the MAX5054BATA+T datasheet, MAX5054BATA+T pinout, MAX5054BATA+T application, or MAX5054BATA+T equivalent, key selection criteria include TTL input compatibility, dual independent inverting/noninverting input pairs per channel, thermally enhanced 8-pin TDFN-EP package, and shoot-through prevention logic for high-frequency power stage control.

Technical Context

The MAX5054BATA+T implements break-before-make control logic to eliminate shoot-through during output transitions, reducing quiescent supply current at high switching frequencies. Its TTL-compatible inputs accept 2.1V VIH and 0.8V VIL thresholds with 0.3V hysteresis, tolerate up to +18V regardless of VDD, and exhibit only 2.5pF input capacitance.

Each channel integrates low-R_ON p-channel and n-channel totem-pole outputs, enabling fast turn-on/turn-off of high-gate-charge MOSFETs. Propagation delay matching is specified at ≤2ns (Δt_ON-OFF) and ≤1ns (Δt_A-B) under VDD = 15V/CL = 10,000pF conditions, supporting precise timing-critical synchronous rectification and half-bridge drive.

FAQ

What logic voltage levels does the MAX5054BATA+T accept?

The MAX5054BATA+T accepts TTL-compatible logic inputs: VIH = 2.1V (min), VIL = 0.8V (max), with 0.3V hysteresis. Inputs tolerate up to +18V regardless of VDD, enabling direct interfacing with 3.3V, 5V, or 12V controllers without level shifters. This behavior is confirmed in the Electrical Characteristics table and applies specifically to the MAX5054B variant.

Does the MAX5054BATA+T support independent control of each channel's inverting and noninverting inputs?

Yes, the MAX5054BATA+T provides both INA+ and INA− for Channel A, and INB+ and INB− for Channel B. This dual-input-per-channel architecture allows independent active-high and active-low control of each output, enabling push-pull, enable/shutdown, or phase-modulated drive schemes without external logic gates.

What is the purpose of the exposed pad on the MAX5054BATA+T package?

The exposed pad on the MAX5054BATA+T's 8-pin TDFN-EP package is internally connected to GND and serves as a thermal conduction path-not the primary electrical ground. When soldered to a PCB ground plane, it reduces θ_JA to 41°C/W and enables 1.9W power dissipation. Pin 3 (GND) remains the required signal and power ground connection.

How does the MAX5054BATA+T prevent shoot-through in half-bridge configurations?

The MAX5054BATA+T incorporates internal break-before-make logic that forces a brief dead-time between high-side and low-side FET switching transitions. This prevents simultaneous conduction, eliminating shoot-through current and associated power loss-confirmed in the Detailed Description section and functional block diagram for the MAX5054 variant.

Is the MAX5054BATA+T qualified for automotive applications?

Yes, the MAX5054BATA+T is explicitly qualified for the automotive temperature range of −40°C to +125°C, as stated in the General Description, Ordering Information, and Absolute Maximum Ratings sections. Its packaging, process, and tested specifications meet AEC-Q100 stress requirements for under-hood and powertrain applications.
