Hi Tean 

            I want Serring OC_ADJ for1.9A 

DRV8402 SPEC page 11 Table 2 did not have this data , Could you help to check OC-Adjust Resistor Values for 1.9A?

for exameple : 

DRV8432 SPEC page 14 table 2 have show OC-ADJUST RESISTOR VALUES (kΩ) = 150k  , The MAXIMUM CURRENT BEFORE OC OCCURS (A) is 1.9A

    Hi kerr chang,

    Please note the DRV8402 is "Not Recommended for New Designs". Also please note the recommended maximum Rocp_cbc resistance is 39kOhm.

    The DRV8432 is a pin to pin replacement.
    If 1.9A is the maximum current and the circuit/board has not been designed, there are additional options including:
    1) DRV8412 which does not require the heat sink
    2) DRV8870 DRV8871 and DRV8872
    3) DRV8840 and DRV8842
    4) DRV8881E and DRV8881P
