OPTIREG™ | Multi-CAN Power+ SBC Family
Infineon’s Multi-CAN Power+ System Basis Chips uniquely integrate four CAN FD transceivers while sourcing up to 750mA with highly efficient SMPS Buck/Boost technology
Infineon's Multi-CAN Power + System Basis Chip (SBC) TLE9278B family offers the highest levet of Integration at smallest footprint for automotive applications requiring multiple channels of CAN transceivers like gateways and high-end Body Control Modules (BCM). A high-efficientSwitch 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 under voltage reset. The device offers low-power modes in order to support applications that are connect-ed permanently to the battery. A wake-up from the low-power mode is possible via a message an the buses, via the bi-level sensitive monitoring/wake-up input as well as via the timer. The TLE9278B product family is offered in a very small footprint, exposed pad VQFN-48-31 (7 x 7 mm) power package.
Space saving: Highest density multi-CAN SBC solution in the industry. 80% PCB board space savings by integration 8 chips in 1 single VQFN package with 7x7mm footprint
Energy saving:. Switched Mode Power Supply at greater than 80% efficiency excel 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 failsafe features.
Reduced cost: Boost with integrated FET switch and shunt for 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 reduces design costs and effort, enabling usage in various applications.
The entire family is pin-to–pin and software compatible. The Multi-CAN Power+ SBC family offers variants for main supply voltage of either 5V or 3.3V. Partial Networking option is offered in the “-3” variants. It is also software compatible with the Lite, Mid-Range+ and DC/DC SBC families (TLE94x1, TLE926x & TLE9271..4).
