MM3638, One-cell li-ion/li-polymer battery protection

MITSUMI One-cell li-ion/li-polymer battery protection IC One-cell li-ion/li-polymer battery protection IC MM3638 Series Outline MM3638 series are protection IC for lithium-ion and lithium-polymer battery.

MM3638 protects the battery pack from overcharge, overdischarge, and overcurrent, etc.

by controlling FET SW.

In the One-cell battery pack, on resistance of the FET SW has been used for overcurrent detection.

MM3638 realize overcurrent protection with high accuracy and with no temperature de
