MAX1811ESA+T

Battery Chargers Overview

The MAX1811ESA+T is a USB-powered lithium-ion battery charger manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of up to 6.5V and supports a maximum charging current of 500mA. The device features a charging saturation voltage of 4.2V and includes overcurrent fault protection. Designed for surface-mount technology, it is housed in an 8-pin SOIC package with dimensions of 4.90 x 3.90mm and a height of 1.75mm. The component functions reliably across an industrial temperature range of -40°C to +85°C.

Battery Chargers Feature Summary

• Integrated USB power interface for direct connection to host systems
• Automated charge termination at 4.2V saturation threshold
• Built-in overcurrent protection circuitry for safety compliance

Battery Chargers Applications

• Portable electronic devices powered via USB
• Lithium-ion battery management in consumer electronics
• Compact mobile accessories requiring integrated charging solutions

Battery Chargers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the SOIC-8 footprint matches the target PCB layout constraints. Validate thermal performance requirements against the specified operating temperature range during design phase.

Battery Chargers Selection Notes

Select this component for applications requiring a compact, single-cell lithium-ion charging solution directly powered by a USB source. The fixed 4.2V output suits standard Li-ion cells. Consider the 500mA current limit for smaller capacity batteries. The SOIC-8 package offers a balance between thermal dissipation and board space efficiency for portable designs.

Battery Chargers Part Context

This part belongs to the Maxim Integrated battery management portfolio, specifically designed for USB-powered applications. It simplifies charging circuitry by integrating necessary control logic and power switches into a small form factor. The series targets cost-sensitive consumer electronics where board space and component count are critical design parameters.

Battery Chargers Replacement Considerations

Consult official datasheets for pin-compatible alternatives within the same family. Verify electrical specifications match exactly before substitution. No public substitute part numbers are confirmed in the provided data.
