8 / 17 page  8 FA531X series The detection threshold is -0.17V for FA5314/15 with respect to ground as shown in Figure 17. The operation is similar to that of FA5310B/11B/16/17 except the threshold is minus voltage compared to that which is plus voltage for FA5310B/11B/16/17. Figure 18 is a timing chart which illustrates current limiting operations. 6. Undervoltage lockout circuit The IC incorporates a circuit which prevents the IC from malfunctioning when the supply voltage drops. When the supply voltage is raised from 0V, the IC starts operation with VCC=VCC ON. If the supply voltage drops, the IC shuts its output down when VCC=VCC OFF. When the undervoltage lockout circuit operates, the CS pin goes low to reset the IC. 7. Output circuit As shown in Figure 19, the IC's totem-pole output can directly drive the MOSFET. The OUT pin can source and sink currents of up to 1.5A or 1.0A. If IC operation stops when the undervoltage lockout circuit operates, the gate voltage of the MOSFET goes low and the MOSFET is shut down.
