Figure 13. FSDX-series FPS Full Range EMI Scan (67KHz,
8. Adjusting Current limit function: As shown in fig 14, a
combined 2.8kΩ internal resistance is connected into the
non-inverting lead on the PWM comparator. A external
resistance of A on the current limit pin forms a parallel resis-
tance with the 2.8kΩ when the internal diodes are biased by
the main current source of 900uA.

For example, FSDx0365RN has a typical Sense FET current
limit (I
ited to 1A by inserting a 2.4kΩ between the current limit pin
and ground which is derived from the following equations:
2.15: 1 = 2.8kΩ : XkΩ ,
X = 1.3kΩ,
Since X represents the resistance of the parallel network, A
can be calculated using the following equation:
A = X / (1 - (X/2.8kΩ))
