Application Circuit Example
• Stepping motor driver circuit (DM = Low)
The formulae for setting the constants in the examples of the application circuits above are as follows :
Constant current (100%) setting
Chopping frequency setting
Timer latch time when the output is short-circuited
Short-circuit state
detection monitor
Position detection
When VREF = 1.5V
Logic input
monitor
Clock input

I OUT = VREF/5/RF resistance
Fchop = Ichop/ (Cchop × Vtchop × 2)
Tcem = Ccem × Vtcem/Icem
= 1.5V/5/0.3Ω = 1.0A
= 10μA/ (200pF × 0.5V × 2) = 50kHz
= 100pF × 1V/10μA = 10μs
