MAX1647EAP+

Battery Chargers Overview

The MAX1647EAP+ is a chemistry-independent battery charger controller manufactured by Analog Devices Inc./Maxim Integrated. It supports lithium-ion, NiCd, NiMH, and lead-acid batteries with a maximum input voltage of 28V and battery voltage up to 18V. The device offers configurable charging currents of 4A, 2A, or 1A via an Intel SMBus interface. It features ±0.75% voltage accuracy and includes thermal safety protection using a battery thermistor. Packaged in a 20-pin SSOP.

Battery Chargers Feature Summary

• Chemistry-independent charging capability for multiple battery types including Li-Ion, NiCd, NiMH, and lead-acid.
• Controlled via Intel System Management Bus (SMBus) interface for setting charge voltage and current.
• Includes interrupt signals to host upon power application or battery insertion/removal.
• Thermistor-based safety protection integrated into the charging circuit.

Battery Chargers Applications

• Laptop computers
• Personal digital assistants

Battery Chargers Procurement Notes

Verify component authenticity through authorized distributors due to discontinued status. Confirm RoHS compliance details as specified in official documentation. Ensure compatibility with existing SMBus host controllers. Check for alternative sources if original manufacturing supply is exhausted. Validate package integrity upon receipt.

Battery Chargers Selection Notes

Select this component for applications requiring multi-chemistry support without hardware changes. Ideal for systems needing precise voltage regulation and SMBus integration. Suitable for portable devices where thermistor-based thermal management is required. Consider pinout compatibility with existing PCB layouts.

Battery Chargers Part Context
