[Outline]
The MW3790 is a voltage monitoring IC with a function of the protection IC for lithium ion batteries.
For a solution including a charge circuit, the MW3790 on the battery pack realizes accurate measurement of the battery voltage. This solution can maximize the CC (constant current) charge mode of the charge circuit, and reduce the charge. As a communication interface, MIPI® BIF, which is a battery interface developed by MIPI® Alliance (an international organization), is used.
