MAX1259EWE+

Overview

The MAX1259EWE+ is a battery management integrated circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates with a working supply voltage of 5 V and provides an output voltage of 3 V at a maximum current of 250 mA. The device is housed in a WSOIC-16 surface-mount package. It functions within a temperature range of -40°C to +85°C. This component is classified as a charge management IC within the PMIC category.

Feature Summary

• Integrated battery charge management functionality
• Surface-mount WSOIC-16 packaging for compact board integration

Applications

• Battery-powered portable electronics
• Consumer devices requiring single-cell charging
• Industrial equipment with battery backup systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance documentation matches specific revision requirements. Validate package integrity upon receipt, as discontinued items may have extended storage periods affecting solderability. Ensure design-in compatibility with existing power architectures before finalizing procurement decisions.

Selection Notes

Select this component when a dedicated single-cell battery charger solution is required with fixed output parameters. The WSOIC-16 package suits applications needing moderate pin counts without excessive board space consumption. Consider thermal performance limits defined by the specified operating temperature range during system design. Evaluate alternative active parts if long-term supply continuity is critical for production lifecycles.

Part Context

This part belongs to the MAX1259 series of battery managers from Analog Devices/Maxim Integrated. It serves as a specialized power management solution for single-cell lithium-ion or lithium-polymer batteries. The E suffix indicates industrial temperature rating, while WE denotes the wide SOIC package type. The '+' suffix signifies lead-free and RoHS compliant manufacturing.

Replacement Considerations

No officially confirmed substitute part numbers are available in public documentation. As the product is listed as End-of-Life (EOL), engineers must evaluate functional equivalents from current portfolios or redesign using active components with similar charge management capabilities.
