DW01B

Revision No : 0

status longer than either

TOI1 or TOI2, the DW01B will turn off the discharging MOSFET (M1) and enter to overcurrent/short circuit

status.

7. Release from overcurrent / short circuit status

Under the overcurrent / short-circuit status, the DW01B will turn on the discharging MOSFET (M1) and restore to normal

operation status when the CS pin voltage is less than VOI1 and either the load has been removed or the impedance between

BATT + and BATT- is >500KΩ.

Note: When the battery is installed to the protection circuit for the first time, the circuit may not enter into normal operation status, which causing the

battery not able to discharge. When this phenomenon happens, simply short the CS to GND, the circuit will be back to normal.
