Application Information (32SDIPH: , 28SSOPH: (#))
1. Hall Input
The input signal of the hall sensor requires larger amplitude than 100mVo-p. The operating voltage level of the hall sensor is from 1.2V ~ VCC1-0.8V.

11 (22 Pin) RS (0.5)
12 (25 Pin)
The RS (Output current sensing resistor ) is connected to GOUT and Approx. 0.5, It converts motor current to a voltage which is feedback amplifier.
3. Motor Speed Control (Input Current Limitation)
The maxmum output current is limitted by the ILIM (Current limiting) voltage. If current limitation is not in use then connect it to VCC1. The control gain is approx. 0.67A/V as follows. GML = IO / VLIM = (IO2 - IO1) / (VLIM2 - VLIM1), where VLIM1 = 1.45V Output current=IO1 VLIM2 = 1.55V Output current=IO2
