Each of the current modes operates with the follow sequence.
The IC enters charge mode when the chopping oscillation starts. (A period of charge mode is forcibly present in 1/8
of the period, regardless of which of the coil current (ICOIL) and the set current (IREF) is larger.)
In charge mode, the coil current (ICOIL) and the set current (IREF) are compared.
If an ICOIL < IREF state exists during the charge period:
The IC operates in charge mode until ICOIL
≥ IREF. After that, it switches to slow decay mode and then switches to
fast decay mode in the last 1/8 of the period.
If no ICOIL < IREF state exists during the charge period:
The IC switches to fast decay mode and the coil current is attenuated with the fast decay operation until the end of the
chopping period.
The above operation is repeated. Normally, in the sine wave increasing direction the IC operates in slow (+fast) decay
mode, and in the sine wave decreasing direction the IC operates in fast decay mode until the current is attenuated and
reaches the set value and the IC operates in slow decay mode.
