MAX4842AELT+T

Product Overview

The MAX4842AELT+T from Analog Devices Inc./Maxim Integrated is an overvoltage protection controller integrated circuit in a compact power-management package. It is a specialized PMIC in a surface-mount 6-WFDFN package, with a 6-µDFN (1.5x1) device package. The device operates from a supply voltage range of 1.2 V to 28 V and has a supply current of 75 µA. Its operating temperature range is -40°C to 85°C (TA). The supply voltage and package size are primary selection parameters.

Key Features

• Overvoltage protection controller function for power-management applications.
• Supply voltage range of 1.2 V to 28 V.
• Supply current of 75 µA.
• Operating temperature range of -40°C to 85°C (TA).
• Surface-mount 6-WFDFN package.
• 6-µDFN (1.5x1) device package.

Applications

• Overvoltage protection control in compact board-level circuits.
• Specialized PMIC functions in surface-mount protection assemblies.
• Designs requiring a 6-µDFN (1.5x1) protection controller footprint.

Design & Procurement Notes

The 1.2 V to 28 V supply range and 75 µA supply current should be matched to the expected operating conditions of the target circuit. Thermal and environmental design should account for the -40°C to 85°C (TA) range. The -40°C to 85°C (TA) range should be checked against the ambient conditions of the final assembly. Layout planning must accommodate the 6-WFDFN / 6-µDFN (1.5x1) surface-mount package and the associated surface-mount assembly constraints. Because the device is a specialized PMIC, its role should be considered within the overall power-management architecture. The 75 µA supply current should be included in power-budget calculations.
