MAX5055BASA+T

Overview

The MAX5055BASA+T 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 an inverting configuration with maximum turn-on and turn-off delay times of 35 ns each. Rise and fall times are specified at 85 ns and 75 ns, respectively. It functions reliably across an operating temperature range from -40°C to +125°C. The component is housed in an SOIC-8 surface-mount package.

Feature Summary

• Dual-channel architecture providing independent control for two MOSFETs
• High-speed switching capability with nanosecond-level propagation delays
• Robust thermal performance supporting high junction temperatures up to 125°C

Applications

• Synchronous rectification in DC-DC converters
• Half-bridge and full-bridge power stage driving
• Motor control applications requiring precise timing

Procurement Notes

Verify the specific suffix and manufacturer documentation to confirm pinout compatibility and electrical specifications before integration. Ensure that the supply voltage remains strictly within the 4 V to 15 V limits to prevent device damage. Confirm that the PCB layout supports the SOIC-8 package dimensions and thermal requirements for reliable operation.

Selection Notes

Select this component when dual isolated or non-isolated gate drive signals are required for synchronous power stages. The 4 A output current capability suits medium-power MOSFETs. Consider the inverting logic configuration during circuit design to ensure correct signal alignment with control inputs.

Part Context

This part belongs to the MAX5055B series of high-performance gate drivers. It is categorized under PMIC and MOSFET Gate Drivers within the Analog Devices portfolio.
