The meaning of H/L in TRI signal and H/OPEN in TRO signal are as follows.
TRI = High
→
SC
4
= High
TRI = Low
→
SC
4
= Open
The OSC signal refer to following table.
Where,
DEO: Battery Voltage Checker, Pin 36
BTS: Battery Selector, Pin 34
Users can’t check the V
DET1
because V
DET1
is selected automatically inside the KA3050 in 6V battery usage.
But step-up circuit (SUC) can be checked by DEO signal.
The V
DET1
and DEO have hysteresis loop as following graph.
The V
TH1
and V
TH2
refer to electrical characteristics.
