    MB3891 FUNCTIONAL DESCRIPTION (1) MAIN UVLO/BACKUP UVLO Transient power-on surge states or sudden drops in supply voltage (VBAT2) can cause an IC to operate abnor- mally, leading to destruction or damage to system elements. To prevent this type of fault, the undervoltage lockout circuits (UVLO/ Backup UVLO) will shut off the output from OUT1 to V-BACKUP if the supply voltage falls below the UVLO circuit threshold voltage (3.0 V/2.8 V typ.).

    MB3891 (8) LDO5 The LDO5 circuits uses the reference voltage supply and generates an output voltage (2.8 V typ.) at the OUT5 terminal (pin 57) when the OUT1 terminal (pin 12,13) is in output state and an “H” level signal is input at the CONT5 terminal (pin 57).
