4.6 Integrated Protection

DRV8376 integrates a wide range of protections for a reliable system design that includes:

  • Over current Protection (OCP) against Short circuit events
  • Cycle-by-cycle current limit (ILIMIT) to eliminate overheating and stress during overload conditions
  • Configurable over voltage protection (OVP)
  • Supply and charge pump under voltage protection to eliminate undesired operation.
  • Over temperature warning and shutdown (OTW and OTSD)

The device offers an SPI option for detailed fault diagnostics and control. Figure 4-4 shows the over current protection of DRV8376 during a short-circuit event at 48V.
