The overcurrent in discharge (OCD) function detects abnormally high current in the discharge direction. The overload in discharge threshold and delay time are configurable via the OCD_CONTROL register. 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 filtered delay before disabling the CHG and DSG FETs. When an OCD event occurs, the LATCH_STATUS[OCD] bit is set to 1 and is latched until it is cleared and the fault condition has been removed.
