Four CAN FD transceivers with efficient SMPS buck-boost technology
A highly-efficient switched-mode power supply (SMPS) buck regulator provides an external 5 V or 3.3 V output voltage at up to 750 mA while an additional DC-DC boost converter supports applications or conditions at low supply input voltages. The device is controlled and monitored via a 16-bit Serial Peripheral Interface (SPI). Additional features include a time-out/window watchdog circuit with reset, fail output, and undervoltage reset. The device offers low-power modes in order to support applications that are connected permanently to the battery. A wake-up from the low-power mode is possible via a message on the buses, via the bi-level sensitive monitoring/wake-up input as well as via the timer. The OPTIREG™ Multi-CAN Power+ SBC family is being offered in a very small-footprint, exposed-pad VQFN-48 (7 x 7 mm²) power package.
Highest integration for auto applications with multi-CAN transceivers
- Space saving: Highest density multi-CAN SBC solution in the industry. 80 percent PCB board space savings by integrating eight chips in one single VQFN package with a 7 x 7 mm² footprint.
- Energy saving: Switched Mode Power Supply at greater than 80 percent efficiency excels in system power savings. Minimal quiescent current and intelligent power-saving modes including stop and sleep mode complement the system solution.
- High system reliability: Comprehensive diagnostics, supervision, and fail-safe features.
- Reduced cost: Boost with integrated FET switch and shunt for a minimum number of external components. Savings in BOM cost, part placing and handling, PCB board size, purchasing, and development.
- Multiple and flexible designs: Compatible hardware and software reduce design costs and effort, enabling usage in various applications.
Excellent software and hardware compatibility with other OPTIREG™ SBC families
The OPTIREG™ Multi-CAN Power+ SBC allows for scalability in terms of amount of CAN FD transceivers. It is also software compatible with other OPTIREG™ SBC families, such as Lite SBC, Mid-Range+ SBC and DCDC SBC
