MAX892LEUA Equivalent & Substitute Parts

Part Overview

The MAX892LEUA is a Power Switch/Driver IC manufactured by Analog Devices Inc./Maxim Integrated, designed for high-side P-channel switching applications. This component operates as a 1:1 power switch with a maximum output current of 250mA and supports load voltages from 2.7V to 5.5V. The device features integrated status flag capability and fault protection including adjustable current limiting and over-temperature protection.

The MAX892LEUA is classified as obsolete, which necessitates identification of equivalent substitute components for new designs or ongoing production requirements. The active product variant MAX892LEUA+ provides functional continuity while maintaining full electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX892LEUA is determined by strict equivalence across the following critical parameters:

• Output Configuration: High Side, P-Channel topology
• Number of Outputs: Single output (1:1 ratio)
• Voltage - Load Range: 2.7V ~ 5.5V compatibility
• Current - Output (Max): 250mA rating
• Rds On (Typical): 250mOhm on-resistance
• Input Type: Non-Inverting control logic
• Features: Status Flag presence
• Fault Protection: Current Limiting (Adjustable) and Over Temperature protection
• Package / Case: 8-TSSOP, 8-MSOP form factor
• Operating Temperature Range: -40°C ~ 85°C
• Mounting Type: Surface Mount

The MAX892LEUA+ qualifies as a direct substitute based on complete alignment with all electrical specifications, mechanical packaging, and functional features. The primary distinction is product status: MAX892LEUA is obsolete while MAX892LEUA+ is active, and packaging format (MAX892LEUA+ is supplied in Tube packaging).

Parameter Comparison

Engineering Selection Recommendations

The MAX892LEUA+ is the appropriate substitute for the obsolete MAX892LEUA. Both components maintain identical electrical specifications, mechanical packaging dimensions, and functional capabilities. The MAX892LEUA+ carries active product status from Analog Devices Inc./Maxim Integrated, ensuring ongoing availability and manufacturer support.

Both variants satisfy ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for current manufacturing standards. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling.

For new designs or production transitions, the MAX892LEUA+ should be specified to ensure long-term component availability and manufacturer technical support continuity.

Frequently Asked Questions (FAQ)

Q: Can MAX892LEUA+ be used as a direct replacement for MAX892LEUA in existing designs?

A: Yes. The MAX892LEUA+ is electrically and mechanically identical to the MAX892LEUA. All electrical parameters, package dimensions, pin configurations, and functional features are equivalent. The primary difference is product status: MAX892LEUA is obsolete while MAX892LEUA+ is active.

Q: What is the significance of the "+" suffix in MAX892LEUA+?

A: The "+" suffix indicates the active production variant supplied in Tube packaging format. The electrical and functional specifications remain unchanged from the base MAX892LEUA designation.

Q: Are there any compliance or certification differences between MAX892LEUA and MAX892LEUA+?

A: No. Both variants maintain identical RoHS3 compliance, REACH unaffected status, and MSL rating of 1 (Unlimited). Regulatory and environmental compliance requirements are fully satisfied by either component.

Q: What are the critical parameters that define substitution eligibility for this power switch?

A: Substitution requires equivalence across: output configuration (High Side P-Channel), current rating (250mA), load voltage range (2.7V ~ 5.5V), on-resistance (250mOhm typical), input type (Non-Inverting), fault protection features (Current Limiting and Over Temperature), package form factor (8-TSSOP/8-MSOP), and operating temperature range (-40°C ~ 85°C).

Q: Is the 8-TSSOP/8-MSOP package footprint identical between both variants?

A: Yes. Both MAX892LEUA and MAX892LEUA+ use the same 8-TSSOP/8-MSOP package with 0.118" width (3.00mm). PCB layout and component placement are fully compatible.

Q: What inventory status should be considered when selecting between these variants?

A: MAX892LEUA has 2900 pieces in stock (obsolete status). MAX892LEUA+ has 1709 pieces in stock (active status). For new production or long-term requirements, MAX892LEUA+ is the recommended selection due to active manufacturer support and ongoing availability.
