OPTIREG™ | Multi-CAN Power+ SBC Family

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-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 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.

Infineon's System Basis Chip (SBC) families intelligently combine the basic functions that are needed in today’s automotive electronic control units (ECU). Get a general overview of Infineon’s System Basis Chips.
