(5) Constant-current control time chart (chopping operate)
In each current mode, the operation sequence is as described below:
At first of chopping cycle, the IC goes to CHARGE mode. (The Blanking section in which the CHARGE mode
is forced regardless of the magnitudes of the coil current (ICOIL) and the set current (IREF) exists for 1μs.)
In Blanking section, the IC compares the coil current (ICOIL) and the set current (IREF).
If the ICOIL < IREF state is existent in Blanking section.
FAST
SLOW
CHARGE
Coil current
Set current
Forced CHARGE section
Chopping cycle
Current mode
Charge mode continues until ICOIL ≥ IREF. After that the IC switches to SLOW DECAY mode and
then switches to FAST DECAY mode for the last about 1μs.
If the ICOIL < IREF state is non-existent in Blanking section.
FAST
SLOW
CHARGE
Coil current
Set current
Current mode
Forced CHARGE section
Chopping cycle
The IC switches to SLOW DECAY after Blanking section, and then switches to FAST DECAY mode
for the last about 1μs.
The IC repeats the above operation.
No.A1685-8/12
