(1) Normal mode To operate a motor at the maximum current level, set RX to infinity (open). From Fig. A, when the maximum current ripple is designated as IOH, its value will be, RS VRSH Fig. A IOH O Waveform of output current Fig. B Output current vs. Current sense resistor (A) 3 IOH(max)= 0.212×Vb−0.01 Rs 0.169×Vb−0.03 Rs VRSH can be calculated as follows: VRSH=0.19× Vb−0.03 (center value) .................
