Features
1. Overvoltage Protection: It monitors each cell in a battery pack and prevents overcharging, which can lead to cell damage or safety hazards.
2. Undervoltage Protection: Ensures that cells do not discharge below safe levels, maintaining battery health and longevity.
3. Low Quiescent Current: Designed for low power consumption, it maximizes battery life by drawing minimal current when the battery is not in use.
4. Programmable Delay Times: Allows customization of delay times for overvoltage and undervoltage protection, offering flexibility for different applications.
5. Package Type: Available in a compact TSSOP package, facilitating integration into various designs.
These features make the BQ7721609PWR an effective solution for enhancing the safety and reliability of battery-operated devices.
Pinout
The primary function of the BQ7721609PWR is to provide overvoltage protection for each cell in a battery pack. It monitors each cell independently and triggers an alert or takes action (like turning off a charge/discharge path) if any cell exceeds the set overvoltage threshold. This helps in preventing damage to the battery and maintaining safety.
In summary, the BQ7721609PWR is a 16-pin IC providing overvoltage protection for battery cells, ensuring the safe operation of lithium-based batteries.
