Lithium Ion Battery Pack Control IC

MB3838A

■ DESCRIPTION

The MB3838A is a lithium-ion battery pack control IC for 3/4-cell series lithium-ion battery packs in notebook PCs

with 12.6 V/16.8 V charging system, and is designed to control charging and discharging by detecting over-charge,

over-discharge, and over-current conditions.

When the IC detects an over-discharge of the lithium-ion battery, advance warning signal is sent before shutting

off discharge. This function enables data in the notebook PCs memory to be saved to the hard disk.

After the over-discharge is detected and after inputting the PDWN signal (state of quasi-over-discharge) , current

consumption becomes 0 µA to cut all biases of IC.

Therefore, even if the battery pack is left for a long term, use by the re-charge is enabled.

Moreover, because charge and discharge control FET can be turned off by remote on function at the battery pack

unit, the output short-circuit by the misoperation can be prevented.

In addition, because it provides with the reference voltage power supply for the A/D converter and the VDD

regulator, and the cell voltage monitor and the current monitor function are built-in, the remainder amount moni-

toring system with built-in battery pack can be easily composed.
