MAX8890ETCAKM

Power Management - Specialized Overview

The MAX8890ETCAKM is a specialized power management integrated circuit (PMIC) designed for handheld and mobile devices. It operates within a supply voltage range of 2.5V to 5.5V and draws a supply current of 180µA. The device features three outputs with a maximum output current of 0.1A per channel and exhibits a maximum dropout voltage of 0.1V. It is housed in a 12-WQFN package with exposed pad, measuring 4x4 mm, and supports surface mount installation. The component functions across an operating temperature range of -40°C to 85°C.

Power Management - Specialized Feature Summary

• Integrates multiple power management functions into a single compact cell for system simplification
• Supports wide input voltage compatibility suitable for single-cell lithium-ion batteries and USB power sources
• Designed for low-power operation in portable consumer electronics applications

Power Management - Specialized Applications

• Handheld mobile devices
• Portable consumer electronics
• Battery-powered systems requiring integrated power management

Power Management - Specialized Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as records indicate non-compliance for this specific part number variant. Check for obsolescence notices or product change notifications prior to procurement. Ensure the 12-WQFN package type matches PCB footprint requirements. Validate that the 2.5V-5.5V input range aligns with system power architecture.

Power Management - Specialized Selection Notes

Select this component for designs requiring integrated power management in space-constrained mobile applications. Ensure the 180µA supply current meets low-power standby requirements. Verify that the 0.1A output current capability satisfies load demands. Confirm thermal performance within the -40°C to 85°C operating range. Evaluate compatibility with single-cell Li-ion battery architectures.

Power Management - Specialized Part Context

The MAX8890 belongs to Maxim Integrated's portfolio of specialized PMICs targeting mobile and handheld markets. Analog Devices acquired Maxim Integrated, consolidating these product lines. This component represents a dedicated power management solution rather than a general-purpose regulator, optimized for integration in compact wireless devices.
