MAX4428ESA+T

Overview

The MAX4428ESA+T is a dual high-speed MOSFET gate driver manufactured by Analog Devices Inc./Maxim Integrated. It operates with a minimum supply voltage of 4.5 V and features a SOIC-Narrow-8 surface-mount package. The device provides two outputs with rise and fall times of 30 ns each, supporting low-side switching applications. It functions within a temperature range starting at -40°C and accepts CMOS or TTL logic inputs.

Feature Summary

• Dual-channel configuration for independent control of multiple MOSFETs
• High-speed switching capability with 30 ns transition times
• Compatible with standard CMOS and TTL logic families

Applications

• Low-side MOSFET driving in power conversion circuits
• Industrial motor control systems requiring fast switching
• General-purpose power management IC interfaces

Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm RoHS compliance details as specified in official documentation. Ensure the SOIC-8 package matches design requirements. Check for specific ordering suffixes that may affect function or packaging. Validate datasheet revisions against current manufacturing standards before integration.

Selection Notes

Select this component when dual low-side drive is required with minimal propagation delay. The 1.5A output capability suits moderate load applications. Consider thermal dissipation limits of 471 mW during operation. Verify input logic levels align with system microcontrollers. Evaluate package constraints against PCB layout space limitations.

Part Context

This part belongs to the MAX4427 series of high-speed gate drivers. It shares similar electrical characteristics with the MAX4427 but offers dual channel functionality. The series is designed for efficient power switching in compact form factors. Analog Devices integrates this technology into broader power management solutions.

Replacement Considerations

The MAX4427ESA-T serves as a related single-channel alternative within the same family. Cross-reference pinouts and electrical specifications carefully before substitution. Verify that the replacement meets the required 30 ns switching speed and 4.5 V minimum supply voltage.
