Application Circuit and Note:

(1)Current Switching - Direct Setting Method:

1.Supply Voltage : apply voltage Vdd。

2.Measure the Overcurrent Value : Vset pin and Vout pin are short-circuited,

and output pin does not need to be connected to any load which is as shown

in Fig.11. Users can set the IP overcurrent value by putting the target current

which is flowing through this hole. Then, measure the output voltage (Vout)

directly by a multimeter under DC mode and records this voltage.

3.Set the Overcurrent Value : Vset pin and Vout pin are open-circuited, which

is shown in Fig.12. The Vset pin input the above-mentioned measured voltage

value. The VIP is an internal Hall sensing signal, which converts into a

proportional voltage according to the IP current.

4.Output : the output voltage levels will change according to the Vset voltage.

Output “High” when VIP > Vset

Output “Low” when VIP < Vset
