Renesas provides an efficient power distribution network solution based on Intelligent Power Device (IPD) technologies. The intelligent protection and diagnostic functions of the IPDs increase the safety level over mechanical relays. This solution optimizes wiring harnesses and improve reliability by adding current monitoring capabilities.
Benefits
- Reduce the size and weight of a fuse box by integrating 10 output channels on a compact sized board, aligning to the smart e-fuse concept.
- E-fuses offer maintenance-free load and wire protection that can be configured and adapted to a variety of cables. Significant higher accuracy of the e-fuses reduces the weight of the wire harness.
- The software-based e-fuse is activated from the current-sense feedback of the IPD to the MCU. The MCU is programmed with an I2t algorithm to implement the fuse function.
- A safe parking mode* can be emulated by switching on the IPD and setting the MCU into a low power mode.
