Voltage

Discharge operation is started

when nominal current is reached.

CT is discharged by RT .

Voltage on RC/Sync was limited

internally to 2.3 V in charge

operation.

When coil current reaches nominal

value, sink transistor is turned off.

Independently of this, RC element is

charged up to 1.8 V and then

discharged.

Charge operation is controlled by

deadtime comparator. RC element is

charged with 1mA.
