Application Information
1. MOTOR CONTROL LOGIC
Mode selection-truth table
Notes:
DIRX: DIRA or DIRB (Direction input)
XOUT: AOUT or BOUT (Non-inverting output)
XOUT: AOUT or BOUT (Inverting output)
X: Indicate each channel (A and B)
2. HOLDING AND SEEKING MODE
In rotating high speed (Seeking Mode), stepping motor is operated by high voltage (V
S1
: Seeking power supply voltage “12”).
In holding mode, stepping motor is operated by low voltage (V
S2
: Holding power supply voltage “5”).
When the PS input signal is high, it will be minimized power consumptio in this device.
3. MAXIMUM DRIVE CURRENT CAPACITY
Peak seeking output current: 0.5A
Continued seeking output current: 0.33A
Holding output current: 0.2A
