ASSP for Power Supply Applications (Secondary Battery)

DC/DC Converter IC for Charging Li-ion Battery

MB39A113

■ DESCRIPTION

MB39A113 is a DC/DC converter IC of pulse width modulation (PWM) type for charging, capable of independently

controlling the output voltage and output current. MB39A113 is suitable for down conversion.

MB39A113 can dynamically control the charge current of the secondary battery, to keep the power constant by

detecting a voltage drop in an AC adapter (dynamically-controlled charging) .

MB39A113 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 dual constant-current control circuits

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

• Built-in AC adapter detection function (fixing the output in the off state when the VCC voltage is lower than the

battery voltage + 0.2 V)

• Possible to prevent mis-detecting of fully-charged state by constant-voltage control state detection function

(CVM terminal)

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