The short-circuit current in discharge (SCD) function detects catastrophic current conditions in the discharge direction. The short-circuit in discharge thresholds and delay times are configurable via the SCD1_CONTROL and SCD2_CONTROL registers. The thresholds and timing can be fine-tuned even further based on a sense resistor with lower resistance or wider tolerance via the PROTECTION_CONTROL register. The detection circuit also incorporates a blanking delay before disabling the CHG and DSG FETs. When an SCD event occurs, the LATCH_STATUS[SCD1] or LATCH_STATUS[SCD2] bit is set to 1 and is latched until it is cleared and the fault condition has been removed.
