PRODUCTION DATA
A MOSFET overcurrent event is sensed by monitoring the current flowing through FETs. If the current across a FET exceeds the IOCP threshold for longer than the tOCP deglitch time, an OCP event is recognized and action is done according to the OCP_MODE bit. On hardware interface devices, the IOCP threshold is set via OCP/SR pin, the tOCP_DEG is fixed at 0.6-μs, and the OCP_MODE bit is configured for latched shutdown. On SPI devices, the IOCP threshold is set through the OCP_LVL SPI register, the tOCP_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.
