MAX5056BASA Low-Side Gate Driver IC

Part Overview

The MAX5056BASA is a low-side gate driver IC manufactured by Analog Devices Inc./Maxim Integrated, designed for driving N-channel MOSFETs in power management applications. This device features independent dual-channel configuration with non-inverting logic inputs and is housed in an 8-SOIC surface mount package.

The MAX5056BASA is classified as obsolete, which necessitates identification of equivalent substitute components for new procurement and design continuity. Finding suitable alternatives ensures project timelines are maintained and supply chain reliability is preserved.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX5056BASA is determined by strict equivalence across the following critical parameters:

• Driven configuration (Low-Side)
• Number of independent driver channels (2)
• Gate type (N-Channel MOSFET)
• Supply voltage range (4V ~ 15V)
• Logic voltage thresholds (VIL 0.8V, VIH 2.1V)
• Peak output current capability (4A source, 4A sink)
• Input logic type (Non-Inverting)
• Package type (8-SOIC)
• Operating temperature range (-40°C ~ 150°C)

The MAX5056BASA+ qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility across all parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

The MAX5056BASA+ is a direct functional and mechanical equivalent to the MAX5056BASA. Both devices maintain identical electrical performance specifications and package dimensions, enabling pin-for-pin substitution in circuit designs.

The primary distinction between these parts is product status: the MAX5056BASA is classified as obsolete, while the MAX5056BASA+ is designated as not for new designs. Both devices carry ROHS3 compliance and unlimited moisture sensitivity rating, confirming regulatory equivalence.

Selection between these parts should be based on component availability and procurement timelines, as electrical and mechanical compatibility is fully established.

Frequently Asked Questions (FAQ)

Q: Can the MAX5056BASA+ be used as a direct replacement for the MAX5056BASA in existing designs?

A: Yes. The MAX5056BASA+ is electrically and mechanically equivalent to the MAX5056BASA. All electrical parameters, logic thresholds, output current ratings, timing characteristics, and package dimensions are identical, enabling direct substitution without circuit modification.

Q: Are there any differences in supply voltage or operating temperature between these parts?

A: No. Both the MAX5056BASA and MAX5056BASA+ operate across the same supply voltage range (4V ~ 15V) and temperature range (-40°C ~ 150°C). Logic voltage thresholds and thermal specifications are identical.

Q: What is the significance of the "+" suffix in the MAX5056BASA+ part number?

A: The "+" suffix typically indicates a packaging or distribution variant. In this case, the MAX5056BASA+ is supplied in tube packaging, whereas the original MAX5056BASA packaging is not specified. The electrical and functional specifications remain unchanged.

Q: Are both parts RoHS compliant?

A: Yes. Both the MAX5056BASA and MAX5056BASA+ are ROHS3 compliant and carry unlimited moisture sensitivity rating (MSL 1), confirming environmental and regulatory equivalence.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. The 8-SOIC package dimensions (0.154" width, 3.90mm) are identical for both parts, and all pin assignments and electrical characteristics match. No PCB layout modifications are required for substitution.
