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.
Features
- S.
- 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.
