MAX17604ASA+

Overview

The MAX17604ASA+ is a dual low-side MOSFET gate driver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4V to 14V and supports logic input levels of 2V (VIL) and 4.25V (VIH). The device provides independent outputs with a peak sink/source current capability of 4A per channel. Proprietary features include programmable dead-time control and shoot-through protection to prevent cross-conduction in half-bridge configurations. It utilizes an 8-SOIC surface-mount package and is rated for junction temperatures up to 150°C.

Feature Summary

• Integrated programmable dead-time control for optimized switching performance
• Shoot-through protection mechanism prevents simultaneous conduction
• Independent dual-channel architecture for flexible drive configurations

Applications

• Half-bridge power stage driving
• Synchronous buck converter output stages
• Motor driver circuits

Procurement Notes

Verify the specific suffix 'ASA+' against official manufacturer documentation to confirm pinout compatibility and thermal specifications. Confirm that the 8-SOIC package dimensions match the target PCB footprint. Ensure the operating temperature range aligns with system requirements, as industrial variants may differ from commercial grades.

Selection Notes

Select this component when high peak current drive is required for low-side N-channel MOSFETs. The integrated dead-time control simplifies design compared to discrete solutions. Verify that the input logic voltage levels are compatible with the controlling microcontroller or FPGA signals before finalizing the selection.

Part Context

This part belongs to the MAX17604 series of dual MOSFET drivers. It is distinct from evaluation kits like the MAX17604EVKIT and other package variants such as the TDFN or UMAX versions. The SOIC package offers a balance between thermal performance and ease of manual assembly for prototyping.

Replacement Considerations

Cross-reference with other MAX17604 family members like MAX17604ATA+T or MAX17604AUA+T if different packaging is required. Verify functional equivalence regarding dead-time settings and current ratings before substitution.
