MAX17605AUA+T

Overview

The MAX17605AUA+T is a high-speed dual MOSFET driver from Analog Devices Inc./Maxim Integrated, designed for efficient switching control in power electronics. It operates on a single +4V to +14V supply and delivers a peak sink/source current of 4A. The device features one non-inverting and one inverting input channel with integrated enable pins for precise timing management. It incorporates internal logic to prevent shoot-through during state transitions and includes inputs rated up to +14V regardless of VDD. With a typical propagation delay of 12ns and package options including µMAX-8, it supports high-frequency applications across an operating temperature range of -40°C to +125°C.

Feature Summary

• Provides independent non-inverting and inverting output channels with dedicated enable controls for flexible gate driving.
• Integrates internal logic circuitry to actively prevent shoot-through currents during output state changes.
• Features robust input protection capable of withstanding voltage spikes up to +14V independent of the supply voltage.

Applications

• High-frequency power conversion circuits requiring fast switching speeds
• Motor drive systems utilizing dual MOSFET configurations
• Industrial power supplies needing reliable gate control

Procurement Notes

Verify the specific suffix 'A' against official documentation to confirm pinout or electrical variations compared to standard variants. Confirm RoHS compliance status through manufacturer declarations. Ensure the supplier provides valid traceability data for the component batch. Cross-reference the datasheet revision date to ensure compatibility with current design specifications. Validate that the packaging type matches the intended automated assembly process requirements.

Selection Notes

Select this component when designing circuits requiring asymmetric drive signals with distinct enable capabilities. The 4A peak current rating suits medium-power MOSFETs where rapid transition times are critical. Consider the ±12ns propagation delay for minimizing switching losses in high-frequency topologies. The wide input voltage tolerance simplifies interface design with various logic families without additional level shifting components.

Part Context

This part belongs to the MAX17600–MAX17605 family of dual MOSFET drivers. The series offers flexibility through various input logic options, including TTL and CMOS-like high-noise margin levels. While other members provide different combinations of inverting and non-inverting outputs, the MAX17605 specifically combines one of each type within a compact surface-mount package suitable for dense PCB layouts.

Replacement Considerations

Direct substitutes include MAX17603AUA+T (dual inverting) and MAX17604AUA+T (dual non-inverting). These parts share identical pinouts and electrical characteristics but differ in logical output configuration. Verify that the application circuit does not strictly require the mixed inverting/non-inverting topology unique to the MAX17605 before substituting.
