State of control terminal:
•“H”→
output is enabled.
•“L”
or “open”
→
output is disabled.
In the case of using a resistance "R" between V
IN
and control.
The current flow into the control terminal while the IC is ON state (I
CONT
) can be reduced when a pull up resistance
"R" is inserted between V
IN
and the control terminal.
The minimum control voltage for ON state (V
CONT (ON)
) is increased due to the voltage drop caused by I
CONT
and the
resistance "R". The I
CONT
is temperature dependence as shown in the "Control Current vs. Temperature"
characteristics. Therefore, the resistance "R" should be carefully selected to ensure the control voltage exceeds the
V
CONT (ON)
over the required temperature range.
