Infineon TLE9278BQX

Infineon's TLE9278BQX offers the highest level 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 (SM PS) buck regulator provides an external 5.0 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 (SPD. 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 an the buses, via the bi-level sensitive monitoring/wake-up input as well as via the timer. The TLE9278BQX is offered in a very small footprint, exposed pad PG-VQFN-48 (7 x 7 mm) power package.
