Li-Ion Battery Protection IC

MB3836

■ DESCRIPTION

The MB3836 is a lithium-ion battery protection IC for three cells series lithium-ion battery pack in a notebook

PC’s. This IC supports charging at 12.6 V and detects an over-charge, over-discharge, and over-current to control

charging and discharging.

The IC has a built-in function that makes the battery rechargeable even when the battery voltage has decreased

to 0 V.

Upon detection of an over-discharge from the lithium-ion battery, the IC outputs a preliminary signal to stop

discharging. This feature allows the notebook PC to save its memory data to hard disk. In addition, the IC allows

the battery to be used up to the over-discharge level of each cell, increasing the operating time.

After detecting an over-discharge, the IC disconnects all of its biases so that its current consumption becomes

0 µA. The IC can therefore make the battery pack rechargeable even when it has been left for an extended period

of time with the output disconnected due to over-discharging.

The battery can also be set into a quasi-over-discharged state even when the cell voltage is equal to or greater

than the over-discharge detection voltage. When the notebook PC is shipped, the IC can prevent the battery pack

from being discharged and turn off its bias sources, allowing the battery pack to be stored for a long time.

The IC’s remote on/off function can turn off the output from the detached battery pack without the need for an

external logic circuit or any mechanism on the notebook PC. This prevents the output from being short-circuited

by a malfunction and facilitates the handling of the battery pack itself.

The MB3836 is the best IC for protecting the lithium-ion battery pack used for a notebook PC.
