Working Principles

BQ294705DSGT operates based on a combination of voltage and current monitoring techniques. It continuously measures the battery voltage and compares it with the preset thresholds. If the voltage exceeds the overvoltage threshold or falls below the undervoltage threshold, the IC disconnects the battery from the load. Additionally, it monitors the current flow and triggers overcurrent protection if the current exceeds the set threshold. The enable pin allows users to activate or deactivate the protection features as needed.

Detailed Application Field Plans

BQ294705DSGT finds applications in various electronic devices that rely on batteries, such as:

1. Portable consumer electronics (e.g., smartphones, tablets, portable gaming devices)
2. Medical devices (e.g., insulin pumps, portable monitors)
3. Power tools and equipment
4. Electric vehicles and hybrid vehicles
5. Renewable energy systems (e.g., solar-powered devices)
