BQ7791502PWR

Battery Management Overview

The BQ7791502PWR is a stackable ultra-low power primary protector designed for 3-series to 5-series lithium-ion battery packs. It operates within a supply voltage range of 3 V to 25 V and features an integrated autonomous cell balancing algorithm with up to 50 mA current capability. The device provides comprehensive protection against overvoltage, undervoltage, overcurrent, and temperature extremes. It supports a HIBERNATE mode for ultra-low standby consumption and utilizes a stackable interface to expand protection for higher series configurations.

Battery Management Feature Summary

• Stackable architecture enabling expansion from 3-series to 20-series or more cells
• Autonomous passive cell balancing with integrated FETs eliminating MCU dependency
• Ultra-low quiescent current in normal and hibernation modes
• Programmable overcurrent delay and independent charge/discharge FET drivers

Battery Management Applications

• Electric tools and garden equipment
• Robot vacuums and floating skateboards
• Electric bicycles
• 10.8 V to 72 V battery packs

Battery Management Procurement Notes

Verify the specific suffix '02' corresponds to the required voltage thresholds and configuration settings. Confirm package type matches design requirements. Check RoHS compliance status. Ensure ESD handling procedures are followed during assembly. Validate compatibility with existing stackable implementations.

Battery Management Selection Notes

Select this component for applications requiring standalone protection without microcontroller intervention. Ideal for designs needing precise voltage monitoring and autonomous balancing. Suitable for space-constrained environments due to integrated FET drivers. Consider stacking capabilities for systems exceeding five series cells.

Battery Management Part Context
