It's not a straight forward value. the voltage across the dw01 CS sense resistor R2, typically 1k ohm determines when the over current triggers. The voltage at CS rises based on the current draw through the battery internal resistance and the control mosfet chosen. Basically the ground voltage at CS will rise as the current increases. See the datasheet for these two sections:
In normal mode, the DW01-P continuously monitors the discharge current by sensing the voltage of
CS pin. If the voltage of CS pin exceeds the overcurrent protection voltage (VOIP) beyond the
overcurrent delay time (TOI1) period, the overcurrent protection circuit operates and discharging is
inhibited by turning off the discharge control MOSFET. The overcurrent condition returns to the normal
mode when the load is released or the impedance between BATT+ and BATT- is larger than 500kΩ.
The DW01-P provides two overcurrent detection levels (0.15V and 1.35V) with two overcurrent delay
time (TOI1 and TOI2) corresponding to each overcurrent detection level.
Selection of External Control MOSFET
Because the overcurrent protection voltage is preset, the threshold current for overcurrent detection is
determined by the turn-on resistance of the charge and discharge control MOSFETs. The turn-on
resistance of the external control MOSFETs can be determined by the equation: RON=VOIP/ (2 x IT) (IT
is the overcurrent threshold current). For example, if the overcurrent threshold current IT is designed to
be 3A, the turn-on resistance of the external control MOSFET must be 25mΩ. Be aware that turn-on
resistance of the MOSFET changes with temperature variation due to heat dissipation. It changes with
the voltage between gate and source as well. (Turn-on resistance of MOSFET increases as the
voltage between gate and source decreases). As the turn-on resistance of the external MOSFET
changes, the design of the overcurrent threshold current changes accordingly.
So it depends entirely on the mosfet chosen and the target current of the boards designer. You could test by measure the mosfets RON or by testing the board with various current loads. Or if your so lucky as to have the mosfet part numbers, look up it's datasheet.
