Battery Management System with Life Indicator for Battery Packs

Being able to quickly check a device's battery status is valuable—and sometimes critical—for many systems to ensure proper power and charge before deployment or use. This battery management system with a life indicator is ideal for battery packs and applications that require a charging system with a mechanism for displaying battery status. It provides an intelligent design to manage 2–4 Li-ion cells and supports a wide input voltage range from 3.9VDC to 23.4VDC, offering flexibility for USB-C charging or Qi-compatible wireless charging. The e-paper display delivers energy-efficient life indication and allows easy status checks at a glance.

System Benefits:

• Fuel gauge IC with an integrated processor provides full battery capacity measurement and programmable protection capabilities to ensure accurate monitoring and control.
• Integrated self-diagnostic functions for functional safety, overcurrent detection for charge and discharge, primary and secondary protection, and voltage and current measurement deliver robust power and battery safeguards.
• Flexible power architecture accommodates a wide input voltage range while enabling operation from the battery, adapter, or both simultaneously, providing high light-load efficiency and fast transient response.
