DC/DC Converter IC for Charging

Li-ion Battery

MB39A114

■ DESCRIPTION

The MB39A114 is a DC/DC converter IC of pulse width modulation (PWM) type for charging, capable of inde-

pendently controlling the output voltage and output current. It is suitable for down conversion.

MB39A114 can dynamically control the secondary battery’s charge current by detecting a voltage drop in an AC

adapter to keep its power constant (dynamically-controlled charging) .

This IC can easily set the charge current value, making it ideal for use as a built-in charging device in products

such as notebook PC.

■ FEATURES

• Built-in constant current control circuit in 2-system.

• Analog control of charge current value is possible. (+INE1 terminal and +INE2 terminal)

• Built-inACadapterdetectionfunction(WhenV^CCislowerthanthebatteryvoltage+0.2V, outputisfixedintheoff.)

• Constant voltage control state detection function (CVM terminal) enables prevention of mis-detection for full

charge.

• Built-in overvoltage detection function (OVP terminal) of charge voltage
