Hi, i'm looking for a hall effect current sensor like the asc712... there isn't a .lib that i could simulate?? or anything possible solution but without use a shunt resistor

Google is your friend. Search on the phrase "spice hall effect"

You are in luck. Here is a subcircuit I made, but you will have
to make your own symbol for it. Change the gain parameter to
corresponding to the dash number of interest. -- a.s.

.subckt ACS712 I+ I- Filter Out V+ V-
.param gain=185m; 185m -05B, 100m -20A, 66m -30A
V1 I+ I- 0
F1 V- 2 V1 {gain}
T1 1 V- 2 V- Td=1u Zo=1
R1 2 V- 1
R2 Filter 2 1k7
G1 V- 3 Filter V- 1
C1 3 V- 1?3 Rpar=1
R3 Out 3 50
G2 V- 3 V+ V- 0.5
R4 V+ V- 2k
.ends ACS712
