5.3 PWM Operation The PWM signal is produced by comparing the input voltage at VSP terminal with the voltage from the internal SAW wave. The duty of the PWM signal can be changed by the triangular wave amplitude level, from the minimum point of VSAWL to the maximum point of VSAWH, and when the level is under VSAWL, the duty becomes 0%, and when the level is over VSAWH, the duty becomes 100%. In addition, chopping with the PWM signal is operated in the bottom arm circuit. 5.4 Over Current Limiting Operation This IC detects over current by checking the voltage drop at the external resistance RS. When the input voltage at RS terminal exceeds the internal reference voltage(Vref), this IC turns off the output of the bottom arm circuit. After over current detection, reset operation is done at every period of the PWM signal. 5.5 Rotating Direction Sense Operation The rotation direction of the motor is detected by the signal at DM terminal. Table 1 shows the output signal for the rotation direction. Table 1. Output signal for the rotation direction Rotating Direction Output (DM terminal) U-V-W L U-W-V H

Vcc under voltrage Detection When Vcc supply voltage becomes below LVSDON(11.5V typ), all of the IGBTs shut off. This condition is recovered when Vcc supply voltage becomes greater than LVSDOFF(12.0V typ). All output IGBTs shut off function When voltage of VSP terminal becomes below 1.23V(typical), all of the IGBTs shut off. If this mode occurs,at motor rotating state, motor will stop and Vs voltage could rise. Please note that this voltage not to exceed 500V.
