TABLE 6. DISCHARGE SET CONFIGURATION REGISTER (ADDR: 05H)
When set to ‘0’, a discharge overcurrent condition automatically turns off the FETs.
When set to ‘1’, a discharge overcurrent condition will not automatically turn off the FETs.
In either case, this condition sets the DOC bit, which also turns on the TEMP3V output.

When set to ‘0’, a discharge short circuit condition turns off the FETs.
When set to ‘1’, a discharge short circuit condition will not automatically turn off the FETs.
In either case, the condition sets the SCD bit, which also turns on the TEMP3V output.
