MAX5057BASA+

Overview

The MAX5057BASA+ is a dual MOSFET gate driver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4 V to 15 V and delivers a peak output current of 4 A. The device features both inverting and non-inverting configurations with two outputs. Typical rise and fall times are 85 ns and 75 ns, respectively. Maximum on and off delay times are limited to 35 ns. It functions reliably across an operating temperature range from -40°C to +125°C.

Feature Summary

• Provides dual independent drive channels for high-side and low-side MOSFET control
• Supports both inverting and non-inverting logic input configurations
• Delivers high peak source and sink currents for rapid switching transitions

Applications

• Half-bridge and full-bridge power converter topologies
• Motor drive circuits requiring isolated or floating gate control
• High-frequency DC-DC conversion systems

Procurement Notes

Verify the specific suffix and package variant against official datasheets before procurement. Confirm RoHS compliance status and lead time availability through authorized distributors. Ensure the ordering information matches the required pinout and electrical specifications for your design.

Selection Notes

Select this component when dual-channel driving with distinct phase requirements is necessary. Consider the 4 A output capability for driving larger MOSFET gates efficiently. Verify that the SOIC-8 package fits the PCB layout constraints and thermal management requirements of the application.

Part Context
