MM3474N01VBE

Overview

The MM3474N01VBE is a monolithic integrated circuit designed for battery protection in 3 to 5-cell lithium-ion and lithium-polymer rechargeable secondary batteries. It provides comprehensive protection against overcharge, overdischarge, discharge overcurrent, and short circuits by detecting voltage anomalies across individual cells. The device operates within an industrial temperature range of -40°C to +85°C and is housed in a TSSOP20 package with a 0.635 mm pitch. It features a maximum supply current of 0.02 mA.

Feature Summary

• Monolithic integration for multi-cell battery protection
• Detection of overcharge, overdischarge, and overcurrent conditions
• Short circuit protection capability
• Industrial temperature grade operation

Applications

• Protection circuits for 3 to 5-cell lithium-ion battery packs
• Safety management systems for lithium-polymer rechargeable batteries
