C、SLA707X series printer, ATM machine with two phase step motor drive single stage

 


Characteristics
The power supply voltage: maximum VBB = 46 V, actual use value: 10 V-44 V
Logic power supply voltage: VDD = 3 V-5.5 V
Output current IO (Max) : 1 A, 1.5 A, 2 A 3 A grade
The clock input incentive (timing generator built-in)
This series has the whole/Half step into (Full/Half step) type product and micro step (μ step) type products. The stepping type product has the whole step to 4 W1-2 micro stepping incentive timing function.
Internal testing resistance (test motor coil current resistance)
With fixed deadline motivated type PWM constant current control. In micro stepping type product, according to the current set can be automatically switch ratio for 3 PWM deadline.
Equipped with reduce the loss the deadline PWM synchronous rectifier circuit
Prevents motor holding or keep noise occurs when the synchronous PWM function
When a standby drive current of the Sleep function reduce
With motor coil open/short circuit protection circuit
