State of control terminal:

•“H”→ output is enabled.

•“L” or “open” → output is disabled.

In the case of using a resistance "R" between VIN and control.

The current flow into the control terminal while the IC is ON state (ICONT) can be reduced when a pull up resistance

"R" is inserted between VIN and the control terminal.

The minimum control voltage for ON state (VCONT(ON)) is increased due to the voltage drop caused by ICONT and the

resistance "R". The ICONT 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

VCONT (ON) over the required temperature range.
