STMicroelectronics STEVAL-PDUBV1 Power Distribution ECU

STMicroelectronics STEVAL-PDUBV1 Power Distribution Electronic Control Unit (ECU) is based on the SPC58NG84E7 Chorus 6M MCU and STi2Fuse devices. This ECU serves as an automotive-intended primary power distribution unit, positioned closer to the loads, reducing overall wiring length within the zone control unit. The STEVAL-PDUBV1 board features two independent power rails with separate inputs. Each rail consists of 13 output channels with different current-carrying capabilities. This board protects primary circuits such as preheating, electric steering, and body computers. The STEVAL-PDUBV1 ECU distributes DC-DC output power sourced from the main battery, and/or the auxiliary battery, and/or the engine, and/or regenerative braking. This ECU is ideal for smart power distribution.

Features
