MAX626CSA+T

Overview

The MAX626CSA+T is a dual low-side power MOSFET driver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.5 V to 18 V and delivers an output current of 2 A. The device features inverting logic compatible with CMOS and TTL standards, ensuring reliable signal interfacing. Key performance metrics include rise and fall times of 20 ns, supporting high-speed switching applications. It is housed in an SOIC-8 surface-mount package and functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

• Dual-channel architecture providing independent low-side drive capabilities for multiple MOSFETs
• Inverting logic configuration ensures compatibility with standard digital control interfaces
• High peak output current capability supports rapid charging and discharging of gate capacitances

Applications

• Synchronous rectification circuits in DC-DC converters
• Motor control systems requiring precise low-side switching
• Power management modules driving external N-channel MOSFETs

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm that the component meets RoHS compliance requirements for your manufacturing process. Ensure the SOIC-8 footprint matches your PCB layout specifications. Check for any regional distribution restrictions or limited availability status before finalizing procurement plans.

Selection Notes

Select this component when dual low-side driving is required without the complexity of high-side integration. The inverting logic simplifies control scheme design by directly mapping input states to opposite output actions. Consider the 2 A output current limit against the total gate charge requirements of the target MOSFETs to ensure adequate switching speed.

Part Context

This part belongs to the MAX626 series of dual low-side MOSFET drivers. It shares functional similarities with other Maxim Integrated drivers but is distinct in its specific output current rating and inverting logic configuration. The series is designed for cost-effective power switching solutions where high-side drive is not necessary.

Replacement Considerations

Direct substitutes may include other dual low-side drivers from the same manufacturer family, such as the MAX626CSA+. Verify pinout compatibility and electrical parameters like output current and propagation delay before substitution.
