MAX4842EXT+

Power Management - Specialized Overview

The MAX4842EXT+ is an overvoltage protection controller IC designed to safeguard low-voltage systems against input voltages up to 28V. It operates within a system voltage range of 1.2V to 28V and features a typical supply current of 130µA. The device utilizes a TSSOP package (specifically SC-88 or SOT-363 form factor) for surface-mount applications. As a specialized power management component, it monitors input conditions and disables output stages when overvoltage events occur, ensuring system integrity.

Power Management - Specialized Procurement Notes

Verify the manufacturer designation matches Analog Devices Inc. or Maxim Integrated. Confirm the suffix 'EXT+' indicates the specific lead-free and RoHS-compliant variant. Ensure the package type corresponds to the TSSOP/SC-88/SOT-363 specification. Check that the component date code reflects new manufacturing standards. Validate authenticity through authorized distribution channels to avoid counterfeit components.

Power Management - Specialized Selection Notes

Select this component when designing systems requiring robust protection against transient or sustained overvoltage conditions up to 28V. Consider the 130µA supply current for low-power applications. Evaluate the TSSOP package constraints for PCB layout. Ensure the operating voltage range aligns with the target system's 1.2V–28V requirements. Verify compatibility with existing power management architectures.

Power Management - Specialized Part Context

The MAX4842 belongs to a family of overvoltage protection ICs, including the MAX4838 through MAX4842 series. These devices are engineered to protect sensitive low-voltage loads from excessive input potentials. The EXT+ suffix typically denotes a specific packaging and environmental compliance configuration within the Maxim Integrated product line.
