The overcurrent in charge (OCC) function detects abnormally high current in the charge direction. The overload in charge threshold and delay time are configurable through the firmware register. The thresholds and timing can be fine-tuned even further based on a sense resistor with lower resistance or wider tolerance through calibration. When an OCC event occurs, the Safety Status flag bit is set to 1 and is latched until it is cleared and the fault condition is removed.
