                                                                                                  TLE9278BQXXUMA1 is a multi-CAN power+ system basis chip. It 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 (SMPS) buck regulator provides an external 5.0V output voltage at up to 750mA while an additional DC/DC boost converter supports applications or conditions at low supply input voltages. The device is controlled and monitored via a 16bit Serial Peripheral Interface (SPI). Additional features include a time-out/window watchdog circuit with reset, fail output and undervoltage reset. Potential applications includes gateways, body control modules, driver assistance, and chassis control.
