APPLICATIONS
(Secondary battery) DC/DC Converter IC for Charging Li-ion Battery MB39A114●
DESCRIPTION
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) .●
FEATURES
● Built-in constant current control circuit in 2-system.● Analog control of charge current value is possible. (+INE1 terminal and +INE2 terminal)
● Built-in AC adapter detection function (When VCC is lower than the battery voltage +0.2 V, output is fixed in the off.)
● 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 (Continued)
