MAX5048AAUT-T

Overview

The MAX5048AAUT-T is a high-speed, single-channel low-side MOSFET gate driver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 4V to 12.6V and is housed in a compact SOT-23-6 surface-mount package. The device features independent pull-up and pull-down outputs capable of delivering peak sink currents of 1.3A and source currents of 7.6A. It includes both inverting and non-inverting inputs with matched transmission delays of approximately 12ns typical. The logic inputs tolerate transient voltages up to +14V regardless of the supply voltage and incorporate hysteresis for noise immunity.

Feature Summary

• Provides independent control over turn-on and turn-off speeds via separate source and sink output stages.
• Features logic inputs that withstand +14V transients independent of the V+ supply voltage.
• Includes internal circuitry to prevent shoot-through conditions during output state transitions.
• Offers matched propagation delays between inverting and non-inverting inputs to minimize timing skew.

Applications

• DC-DC converters
• Motor control systems
• Power MOSFET switching applications
• Switch-mode power supplies
