MAX5057AASA+T

Overview

The MAX5057AASA+T is a low-side gate driver IC manufactured by Analog Devices Inc./Maxim Integrated. It features an independent channel configuration designed for driving N-Channel MOSFETs. The device operates within a supply voltage range of 4V to 20V and draws an operating supply current of 2.4 mA. Key electrical parameters include a maximum turn-on delay time of 35 ns and a maximum turn-off delay time of 35 ns. The power dissipation capability is rated at 1.538 W. The component is housed in an 8-SOIC package with exposed pad (EP) for enhanced thermal performance.

Feature Summary

• Independent low-side gate driver configuration optimized for N-Channel MOSFET switching applications
• Fast switching performance with symmetric 35 ns maximum turn-on and turn-off delay times
• Robust thermal management via exposed pad design supporting up to 1.538 W power dissipation

Applications

• Power factor correction (PFC) circuits requiring low-side switching control
• Synchronous rectification stages in DC-DC converters
• General-purpose high-frequency power switching topologies

Procurement Notes

Verify the specific suffix (+T) indicates tape-and-reel packaging when sourcing. Confirm the manufacturer designation as Analog Devices Inc. or Maxim Integrated, as ownership transitions may affect documentation sources. Ensure the 8-SOIC-EP package footprint matches your PCB layout requirements before procurement.

Selection Notes

Select this component for applications requiring precise timing symmetry between turn-on and turn-off events. The 4V minimum supply voltage allows compatibility with standard logic-level control signals. Consider the 1.538 W power dissipation limit when designing thermal solutions for continuous operation environments.

Part Context

This part belongs to the MAX5057 family of gate drivers from Maxim Integrated, now part of Analog Devices. The 'A' variant typically denotes specific electrical characteristics compared to other revisions. The '+T' suffix confirms RoHS compliance and reel packaging format, distinguishing it from tube-packaged equivalents like the MAX5057AASA+.

Replacement Considerations

The MAX5057BASA+T is a related variant within the same family. Verify differences in power dissipation ratings, as the B variant may have different thermal characteristics. Ensure pinout compatibility and switching speed requirements match before substituting.
