Description
The MB39A114 is a DC/DC converter IC of pulse width modulation (PWM) type for charging, capable of independently controlling the output voltage and output current.
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 volt.
