Protection Circuit that Separates Charge and Discharge Current Paths and Suppresses Heat Generation

Block Circuit　｜　Recommended Products

When setting up 1-cell battery protection circuits, do you encounter any of the following issues?
ABLIC introduces 1-cell battery protection circuits that meet your specific requirements without these common issues.

Specific Requirements:

Able to suppress heat generation in detection resistors and charge and discharge control FETs during rapid charging.
Reduced component costs by optimizing the charge and discharge control FETs respectively, due to the significant difference between charge and discharge currents.

Block Circuit:
Protection Circuit that Separates Charge and Discharge Current Paths and Suppresses Heat Generation

By separating the discharge and charge paths, it is possible to use control FETs suitable for each current value. Additionally, there are no resistors in the charge path, making it ideal for fast charging solutions.
