• Description: GENERAL PURPOSE BATTERY CHARGER CONTROL IC
• Manufacturer: Mitsubishi

To D
Output voltage of D
In Fig.2 Reference Voltage is 2.5V. When Input voltage of IN1 (or IN2,IN3,IN4) is set at
2.8V, the difference between input voltage and Reference Voltage is 0.3V. The difference
voltage (0.3V) multiplied by 4 is 1.2V. 1.2V added to Reference Voltage(2.5V) makes
3.7V which is output voltage of V
The range of output voltage of V
voltage of IN1(or IN2,IN3,IN4) is between 1.9V and 3.1V. (This range of input voltage is
difference from selected Reference Voltage.)
