DS2720AU+T&R

Battery Management Overview

The DS2720AU+T&R is a rechargeable lithium-ion safety circuit designed for single-cell battery protection. It provides overvoltage, undervoltage, overcurrent, short-circuit, and overtemperature protection by controlling high-side N-channel power MOSFETs driven from an internal 9V charge pump. The device features an eight-byte lockable EEPROM and a Dallas 1-Wire interface with a unique 64-bit address. It operates within a temperature range of -40°C to +85°C in an 8-pin micro small outline package.

Battery Management Feature Summary

• Integrated safety circuit providing comprehensive protection against overvoltage, undervoltage, overcurrent, short-circuit, and overtemperature conditions for rechargeable lithium-ion cells.
• Controls high-side N-channel power MOSFETs using an internal 9V charge pump system for efficient power management.
• Includes eight bytes of lockable EEPROM and supports the Dallas 1-Wire interface with a unique 64-bit device address.

Battery Management Applications

• Rechargeable lithium-ion battery pack protection
• Portable electronic devices requiring single-cell battery management
• Power tool battery packs

Battery Management Procurement Notes

Verify the specific suffix 'AU' against official datasheets to confirm the commercial temperature grade (-40°C to +85°C) versus other variants like 'BU'. Confirm RoHS compliance status as indicated by the '+' suffix. Check current availability status as some Maxim Integrated products may be discontinued or subject to last-time buys.

Battery Management Selection Notes

Select this component when a dedicated single-cell lithium-ion protection IC with integrated EEPROM and 1-Wire communication is required. Ensure the application utilizes external high-side N-channel MOSFETs controlled by the IC. Verify that the operating environment falls within the specified temperature range for the AU suffix variant.
