Output Voltage Switching Function
The SEL pin (pin 10) is capable of output levels of 4.2 V or 4.1 V per battery cell.

Protection Functions
(1) Input voltage detector circuit (VIDET)
When the input voltage supply from the AC adapter or other source detected at the Vin1 pin (pin 1) falls below
11 V (MB3813A), or below 7.3 V (MB3833A), or below 6.3 V (MB3843), the internal reference voltage circuit
switches off.
(2) Under voltage lockout circuit (UVLO)
Power surges at power-on, or momentary under-voltage situations can cause abnormal operation in a control
IC, which may lead to damage or deterioration in systems. This circuit prevents abnormal peration during times
of low voltage by using the supply voltage to detect the level of the internal reference voltage, and switching
off the external output transistor to create a 100% rest interval. Once the supply voltage recovers to a level
above the threshold voltage of the under voltage lockout circuit, operation is restored.
