• Aerospace power management circuits

Procurement Notes

Verify the specific suffix 'EPA+' confirms the 8-DIP through-hole package and lead-free compliance. Confirm the manufacturer designation as Analog Devices Inc./Maxim Integrated for authenticity. Ensure the part status is active if new production is required, noting that older stock may be obsolete.

Selection Notes

Select this component for applications requiring robust low-side switching with high input voltage tolerance. The supply-independent logic simplifies interface design across varying supply rails. Consider the 1.5A output current capability for driving medium-power MOSFETs efficiently without external buffering.

Part Context

This part belongs to the Maxim Integrated gate driver family, designed for reliable switching in power conversion topologies. It complements other drivers in the series by offering specific low-side functionality with integrated protection features suitable for demanding environments.

Replacement Considerations

Check for direct pin-compatible substitutes within the same product family. Verify equivalent current drive capabilities and input logic compatibility before substitution.
