(8) Output circuit

The IC contains a push-pull output stage and can directly drive MOSFETs (FA7700: N ch, FA7701: P ch). The

maximum peak current of the output stage is a sink current of +150mA, and a source current of - 400mA. The

IC can also drive NPN, and PNP transistors. The maximum peak current in such cases is ± 50mA. Be sure to

design the output current considering the rating of power dissipation.

(9) Power good signal circuit/ Undervoltage lockout circuit

The IC contains a protection circuit against Undervoltage malfunctions to protect the circuit from the damage

caused by malfunctions when the supply voltage drops. When the supply voltage rises from 0V, the circuit starts

to operate at VCC of 2.07V(typ.) and outputs generate pulses. If a drop of the supply voltage occurs, it stops

output at VCC of 1.93V(typ.). when it occurs, the CS terminal is turned to LOW level and then it is reset. The

power good signal circuit monitors the voltage of REF terminal, and stops output until the voltage of REF

terminal excesses approximately 2V to prevent malfunctions.
