Motor Solution
C、SLA707X series printer, ATM machine with two phase step motor drive single stage
Characteristics
l The power supply voltage: maximum VBB = 46 V, actual use value: 10 V-44 V
l Logic power supply voltage: VDD = 3 V-5.5 V
l Output current IO (Max) : 1 A, 1.5 A, 2 A 3 A grade
l The clock input incentive (timing generator built-in)
l 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.
l Internal testing resistance (test motor coil current resistance)
l 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.
l Equipped with reduce the loss the deadline PWM synchronous rectifier circuit
l Prevents motor holding or keep noise occurs when the synchronous PWM function
l When a standby drive current of the Sleep function reduce
l With motor coil open/short circuit protection circuit
