Four CAN FD transceivers with efficient SMPS buck-boost technology
A highly-efficient Switch 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 TLE9278B product family is offered in a very small footprint, exposed pad VQFN-48-31 (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 compatibility with other SBC families
The entire family is pin–to–pin and software compatible. The Multi-CAN Power+ SBC family offers variants for a main supply voltage of either 5 V or 3.3 V. A 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, TLE9272, TLE9273, and TLE9274).
