%A0; Overview

With batteries used for electronic tools requiring greater capacity in recent years, secondary lithium ion batteries are being used more often.
There are currently 3 to 5 cells within a battery, and the 3-cell battery specifications (10.8V) that make up the majority of the market have a greater need for temperature protection and multi-step overcurrent protection.
Using the enables a lower cost and higher level of safety than could be achieved using existing circuits.

§ Features

1.

Overcharge, overdischarge and overcurrent protection functions built-in.

2.

Monitor and protect against discharge overcurrent with 3 steps (overcurrent 1, overcurrent 2, short circuit protection)

3.

Detection of high and low temperatures with 3 values with an external NTC thermistor to protect the battery pack.

4.

Charging prohibited/permitted can be selected for 0V battery (optional)
