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
V
CC
=V
CC ON
.
If the supply voltage drops, the IC shuts its output down when
V
CC
=V
CC 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.
