In each current mode, the operation sequence is as described below :
At rise of chopping frequency, the CHARGE mode begins.(The section in which the CHARGE mode is forced
regardless of the magnitude of the coil current (ICOIL) and set current (IREF) exists for 1/16 of one chopping cycle.)
The coil current (ICOIL) and set current (IREF) are compared in this forced CHARGE section.
When (ICOIL<IREF) state exists in the forced CHARGE section ;
CHARGE mode up to ICOIL
≥ IREF, then followed by changeover to the SLOW DECAY mode, and finally
by the FAST DECAY mode for the 1/16 portion of one chopping cycle.
When (ICOIL<IREF) state does not exist in the forced CHARGE section;
The FAST DECAY mode begins. The coil current is attenuated in the FAST DECAY mode till one cycle of
chopping is over.
Above operations are repeated. Normally, the SLOW (+FAST) DECAY mode continues in the sine wave increasing
direction, then entering the FAST DECAY mode till the current is attenuated to the set level and followed by the SLOW
DECAY mode.
