Product Attributes

Features

• Designed to protect 4~7 series-connected Li-ion/polymer, LiFePO₄, or lithium titanate battery packs, reducing the risk of battery damage or degraded cycle life caused by overcharge, over-discharge, over-temperature, and/or overcurrent conditions
• Built-in high-accuracy voltage detection circuit
• ±25mV overcharge detection voltage accuracy ensures safe full-capacity charging
• ±10mV current detection voltage accuracy ensures precise overcurrent discharge triggering
• Charge over-temperature and discharge over-temperature protection thresholds independently configurable via external resistors
• Built-in three-stage discharge overcurrent detection circuit
• Directly drives external N-channel charge MOSFET and N-channel discharge MOSFET; dedicated CCTL and DCTL pins allow user-controlled charge/discharge MOSFET operation per application requirements
• Multi-chip cascading support for higher series battery count applications
• Low-power design minimizes quiescent current drain during battery pack storage
• Built-in independent charge over-temperature and discharge over-temperature protection; charge and discharge over-temperature thresholds independently configurable via external resistors
• Built-in charge low-temperature protection
• Various delay times configurable via external capacitors
• Multi-chip cascading support
• Electronic latch function
• Low quiescent current: 25μA typical VCC in active mode; <1μA in sleep mode

Applications

• E-bikes, electric scooters
• Power tools
• Home appliances
• Backup battery systems
