MAX620EWN High-Side Gate Driver IC

Part Overview

The MAX620EWN is a high-side gate driver IC manufactured by Analog Devices Inc./Maxim Integrated, designed for driving N-channel MOSFETs in power management applications. This component operates as a non-inverting driver with independent channel configuration and is housed in an 18-SOIC surface mount package.

The MAX620EWN is classified as obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term production requirements for systems utilizing this gate driver topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX620EWN is determined by strict equivalence across the following critical parameters:

• Driven configuration (high-side operation)
• Number of independent drivers (4 channels)
• Gate type (N-channel MOSFET)
• Input logic type (non-inverting)
• Supply voltage range (4.5V ~ 16.5V)
• Logic voltage thresholds (VIL 0.8V, VIH 2.4V)
• Rise and fall time specifications (1.7µs, 2.5µs typical)
• Operating temperature range (-40°C ~ 85°C)
• Package form factor (18-SOIC)
• Surface mount mounting type

Substitute parts must maintain identical electrical performance and mechanical compatibility across all these parameters to ensure direct replacement capability without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The MAX620EWN+ serves as the direct substitute for the obsolete MAX620EWN. Both parts maintain identical electrical specifications and mechanical compatibility across all critical parameters. The primary distinction is product status: the MAX620EWN+ is active production, ensuring ongoing availability and supply chain continuity.

The MAX620EWN+ achieves ROHS3 compliance, whereas the original MAX620EWN is RoHS non-compliant. This compliance upgrade aligns with current regulatory requirements for electronic components in regulated markets. The MAX620EWN+ is supplied in tube packaging, compared to the unspecified packaging of the original part.

For new designs or production transitions, the MAX620EWN+ is the appropriate selection. For legacy system support requiring the original MAX620EWN, existing inventory of 2140 pieces remains available.

Frequently Asked Questions (FAQ)

Q: Can MAX620EWN+ directly replace MAX620EWN without circuit modification?

A: Yes. The MAX620EWN+ maintains identical electrical specifications, logic thresholds, timing characteristics, and package form factor. Direct substitution is possible without circuit redesign.

Q: What is the significance of the product status difference?

A: The MAX620EWN is classified as obsolete, indicating discontinued manufacturing. The MAX620EWN+ is active production status, ensuring long-term availability and supply reliability for ongoing applications.

Q: Does RoHS3 compliance affect electrical performance?

A: No. RoHS3 compliance reflects material composition and manufacturing process standards. Electrical performance and functional characteristics remain identical between the RoHS non-compliant MAX620EWN and ROHS3 compliant MAX620EWN+.

Q: Are there packaging considerations for substitution?

A: Both parts use identical 18-SOIC surface mount packages. The MAX620EWN+ is supplied in tube packaging. No PCB layout or assembly process modifications are required.

Q: What parameters determine substitution eligibility?

A: Substitution requires equivalence across driven configuration (high-side), driver count (4), gate type (N-channel MOSFET), input logic (non-inverting), supply voltage range (4.5V ~ 16.5V), logic thresholds (0.8V, 2.4V), timing specifications (1.7µs rise, 2.5µs fall), operating temperature (-40°C ~ 85°C), and package form factor (18-SOIC).
