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 helps optimize wiring harnesses and improve reliability by adding current monitoring capabilities.
- Reduces size and weight of the wiring harness by adding a current monitoring function. Aggressive wire diameter reduction is achieved by estimating Joule heating in the wire based on I2t, which is enabled by the IPD current monitoring function and arithmetic processing by the MCU. The reduced wire diameter contributes to a lower BOM cost and a lighter weight wiring harness.
- Reduces maintenance by replacing mechanical relays and metal fuses with IPD.
- I2t model ensures compatibility with metal fuse and reusability of existing design assets.
- System-level validation including the I2t–model overcurrent protection software is under development by Renesas.
