Description : Single or Multi-cells Li Battery Charger IC

■ Features
◆ Accurate voltage detection to determine the lithium battery full voltage
◆ Built-in constant current charging power control loop, the charging current value can be adjusted by external resistors to match pre-charge, fast charge, and charge.
◆ Pre-charge: Over-discharge battery, small current charging to protect battery life.
◆ Charge (turbulent charge): Fully charge the battery, turn to turbulent current charging, to make up for the natural power consumption of the battery, power consumption of the line.
◆ Built-in battery enable function to wake up after the factory, too low energy battery.
◆ Overcharge voltage protection - When the battery voltage exceeds the normal charging voltage range, the charging process is automatically cut off to prevent the battery from leaking, exploding, etc.
◆ Safe charging termination time protection - When the battery is abnormal, when the normal filling condition occurs within a reasonable time, the charging process is forcibly terminated to prevent the battery from leaking and exploding. In the standard working frequency, the value can be selected. For 2 or 4 hours.
◆ Two-color single LED charging status display: Start power, no battery, charge, full, battery abnormal, circuit abnormal.
◆ Adopt one-legged RC line economic shock line. It can fine-tune the charging protection time.
◆ Operating voltage: 5.0 Volt. Package: LS2822S: SOP-8 (150 mil).
◆ When there is no battery: Simultaneously use tiny pulse wave to activate the battery insulated by the lithium protection board, or to wake up the battery that has been out of the factory for a long time (the battery voltage is too low, like no battery).
◆ Pre-Charge: Over-discharged battery, automatically charged at a small constant current to protect battery life.
◆ Pre-Charge Time Out: After the pre-charge time is terminated, the battery voltage cannot rise back to the normal potential, which is regarded as an abnormal battery, forcibly stopping the charging process.
◆ Fast Charge: The normal voltage battery is automatically charged at the set constant current for fast charging process.
◆ Fast Charge Time Out: After the fast charge time expires, the battery voltage can not reach the normal charge level, it is considered to have fully charged the battery, forcibly terminate the charging process to protect the battery life.
◆ Trickle Charge: When the battery voltage reaches the full potential, the LED turns to the full charge. At the same time, if the fast charge time is not terminated, it will be charged at a smaller constant current to increase the battery saturation.
◆ Fast Charge Time Out: After the termination of the charging time, the charging process is terminated.

Description : DC/DC Converter IC for Parallel charging

■ DESCRIPTION
The MB3874 and MB3876 are parallel charging DC/DC converter ICs suitable for down-conversion, which uses pulse width modulation (PWM) for controlling the output voltage and current independently.
These ICs can dynamically control the secondary battery’s charge current by detecting a voltage drop in an AC adapter in order to keep its power constant (dynamically-controlled charging).
The charging method enables quick charging, for example, with the AC adapter during operation of a notebook PC.
The IC also enable parallel charging, or charging two batteries at the same time, dramatically reducing the charging time.
With an on-chip output voltage setting resistor which allows the output voltage to be set at high precision, these ICs are best suited as internal battery chargers for notebook PCs.
The MB3874 support 3-cell battery and the MB3876 support 4-cell battery.
