MAX1822ESA Equivalent & Substitute Parts

Part Overview

The MAX1822ESA is a charge pump switching regulator IC manufactured by Analog Devices Inc./Maxim Integrated, designed for power management applications requiring positive fixed output voltage regulation. This device generates an output voltage of Vin+11V from input sources ranging from 4.6V to 16.5V, delivering up to 25mA output current in an 8-SOIC surface mount package.

The MAX1822ESA is classified as obsolete. Identifying suitable substitute parts is necessary to ensure continued availability for new designs, production continuity, and long-term system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX1822ESA is determined by strict equivalence across the following critical parameters:

• Topology: Charge Pump
• Output Configuration: Positive
• Output Type: Fixed
• Voltage - Input Range: 4.6V to 16.5V
• Voltage - Output: Vin+11V
• Current - Output: 25mA
• Frequency - Switching: 90kHz
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Operating Temperature Range: -40°C ~ 85°C (TA)

Only parts matching all these parameters across the same manufacturer (Analog Devices Inc./Maxim Integrated) and base product number (MAX1822) are classified as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The MAX1822ESA+ is a direct functional equivalent to the MAX1822ESA. Both parts share identical electrical specifications, package configuration, and thermal operating range. The primary distinction is product status: the MAX1822ESA is obsolete, while the MAX1822ESA+ maintains active status with current manufacturer support.

Both parts maintain ROHS3 compliance and carry identical moisture sensitivity ratings (MSL 1 - Unlimited), ensuring compatibility with standard manufacturing and storage protocols. The MAX1822ESA+ is recommended for new designs and production continuity where the MAX1822ESA is no longer available through standard distribution channels.

Frequently Asked Questions (FAQ)

Q: Can MAX1822ESA+ be used as a direct replacement for MAX1822ESA in existing designs?

A: Yes. The MAX1822ESA+ is electrically and mechanically identical to the MAX1822ESA across all specified parameters, including input voltage range, output voltage, output current, switching frequency, package type, and operating temperature range. No circuit modifications are required.

Q: What is the difference between MAX1822ESA and MAX1822ESA+?

A: The primary difference is product status. The MAX1822ESA is obsolete, while the MAX1822ESA+ is active. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical and mechanical specifications.

Q: Are there any packaging differences between these parts?

A: Both parts use the 8-SOIC (0.154", 3.90mm Width) surface mount package. The main part number suffix difference does not indicate package variation.

Q: Do both parts meet the same compliance standards?

A: Yes. Both MAX1822ESA and MAX1822ESA+ are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Both are REACH unaffected and carry the same ECCN and HTSUS classifications.

Q: What output voltage does this charge pump regulator produce?

A: The output voltage is Vin+11V, where Vin is the input voltage. With the specified input range of 4.6V to 16.5V, the output voltage ranges from 14.5V to 27.5V.
