A MOSFET overcurrent event is sensed by monitoring the current flowing through FETs. If the current across a FET exceeds the I_OCP threshold for longer than the t_OCP deglitch time, an OCP event is recognized and action is done according to the OCP_MODE bit. On hardware interface devices, the I_OCP threshold is fixed at 16-A threshold, the t_{OCP_DEG} is fixed at 0.6-µs, and the OCP_MODE bit is configured for latched shutdown. On SPI devices, the I_OCP threshold is set through the OCP_LVL SPI register, the t_{OCP_DEG} is set through the OCP_DEG SPI register, and the OCP_MODE bit can operate in four different modes: OCP latched shutdown, OCP automatic retry, OCP report only, and OCP disabled.
