With 30\u03bcA sleep mode current and AEC-Q100 qualification, it provides the highest integration level for automotive gateway and body control modules, saving up to 80% PCB board space compared to discrete solutions.","working_principle":"The TLE9278BQXXUMA1 integrates multiple power and communication functions into a single chip. The SMPS buck regulator uses an external inductor and internal MOSFET switches to efficiently convert the battery voltage to 5V or 3.3V at up to 750mA. The DC-DC boost converter uses an integrated FET switch and external shunt resistor to generate 6.7V-12V for low battery conditions (cold-crank support). The LDO provides a clean 5V\/100mA rail for off-board sensors. The four CAN FD transceivers handle up to 5Mbps communication with wake-up capability. The SPI interface provides full control and diagnostic readback. The state machine manages SBC modes (Normal, Stop, Sleep, Restart, Fail-Safe) with configurable watchdog, cyclic wake, and fail-safe output control. The VIO pin allows direct connection to 3.3V or 5V microcontrollers.","pin_description":"<table><tr><th>Pin Group<\/th><th>Mnemonic<\/th><th>Description<\/th><\/tr><tr><td>1-4<\/td><td>CAN1H\/CAN1L-CAN4H\/CAN4L<\/td><td>4x CAN FD bus pins<\/td><\/tr><tr><td>5-6<\/td><td>VCC1\/VCC2<\/td><td>SMPS output \/ LDO output<\/td><\/tr><tr><td>7-8<\/td><td>SW\/BST<\/td><td>SMPS switch node \/ bootstrap<\/td><\/tr><tr><td>9<\/td><td>VBAT<\/td><td>Battery supply input<\/td><\/tr><tr><td>10<\/td><td>VIO<\/td><td>I\/O voltage reference pin<\/td><\/tr><tr><td>11-20<\/td><td>SPI\/CS\/CLK\/MISO<\/td><td>SPI communication interface<\/td><\/tr><tr><td>21-24<\/td><td>WK\/FO1-3<\/td><td>Wake input \/ fail-safe outputs<\/td><\/tr><tr><td>25-32<\/td><td>VCC1\/RO\/GPIO<\/td><td>Regulator output \/ reset \/ GPIO<\/td><\/tr><tr><td>33-48<\/td><td>GND\/PGND<\/td><td>Signal and power ground<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Automotive central gateway with 4xCAN FD routing and SMPS 750mA MCU power<\/li>\n<li>ADAS domain controller requiring multiple CAN buses and ASIL-B safety<\/li>\n<li>Body control module (BCM) with 30\u03bcA sleep current battery management<\/li>\n<li>HVAC ECU with boost converter for cold-crank low-voltage operation<\/li>\n<li>Industrial multi-CAN communication node with SMPS power supply<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Difference<\/th><\/tr><tr><td>TLE9274QX<\/td><td>Infineon<\/td><td>2x CAN + 4x LIN SBC variant<\/td><\/tr><tr><td>TLE926x<\/td><td>Infineon<\/td><td>Single CAN, mid-range SBC<\/td><\/tr><tr><td>NXP S32G274A<\/td><td>NXP<\/td><td>MCU with integrated CAN + SBC<\/td><\/tr><tr><td>TJA1145T<\/td><td>NXP<\/td><td>Single CAN SBC with 8\u03bcA sleep<\/td><\/tr><tr><td>NCV7430<\/td><td>onsemi<\/td><td>Single CAN LIN SBC<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/posts\/9164","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/comments?post=9164"}],"version-history":[{"count":0,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/posts\/9164\/revisions"}],"wp:attachment":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/media?parent=9164"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/categories?post=9164"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/tags?post=9164"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/chip_brand?post=9164"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
