Battery Management 3-Series to 5-Series Stackable Ultra-Low-Power Primary Protector With Autonomous Cell Balancing 24-TSSOP -40 to 85

Description of product

Description:

The BQ77915 device is a low-power battery pack protector that implements a suite of voltage, current, and temperature protections and a smart cell balancing algorithm without microcontroller (MCU) control. The device's stackable interface provides simple scaling to support battery cell applications from 3 series to 20 series or more. Protection thresholdsand delays are factory-programmed and available in a variety of configurations. Separate overtemperature and undertemperature thresholds for discharge (OTD and UTD) and charge (OTC and UTC) are provided for added flexibility.

Features:

• Ultra-low quiescent current: 8 µA typ. (NORMAL mode), 2 µA (HIBERNATE mode)
• Full suite of voltage, current, and temperature protections
• Smart passive cell balancing removes cell-to-cell imbalance
• Scalable cell count from 3 series to 20 series or more
