function.
Please select function by MFR_C2_ARA_CONFIG [ E0h ] Initial setting is Power_Good function.
4.1 Power_Good function
Power_Good terminal output is open drain. When you use Power_Good function, please
connect C2 terminal with pull-up resistor. Initial setting of Power_Good signal is negative.
(Please make logic setting by MFR_PGOOD_POLARITY [ E2h ])
If output voltage is beyond setting value of POWER_GOOD_ON [ 5Eh ] , C2 terminal
will be low.
If output voltage is lower than the setting value of POWER_GOOD_OFF [ 5Fh ] ,
C2 terminal will be high.
Also, during 10ms in charging input voltage, voltage level on C2 terminal is unstable.
4.2 Remote control (Secondary side) function
Initial setting of Remote control (secondary side) function is negative and is invalid
when you select function.
Selecting logic and setting for invalid or valid function can be made by MFR_C2_LOGIC [ E1h ].
