Overview

MITSUMI 1cell Li-ion/Li-polymer battery protection IC MM3722 Series 1cell Li-ion/Li-polymer battery protection IC MM3722 Series Outline MM3722 series are Li-ion battery protection IC and detect charge current / discharge current with high precision by current sensing resistor (Rsns).
In the One-cell battery pack, on resistance of the FET SW has been used for over-current/short-current detection.
MM3722 realize over-current/short-current protection with high accuracy and with no temperature dependence by using a chip resistor.
