TLE9278BQX TLE9278BQX - highest level of integration at smallest footprint for all automotive applications requiring multiple channels of CAN transceivers.
A high-efficient switch mode power supply (SMPS) 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 input supply 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 LIN/CAN bus, 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 mm2) power package.
