The Infineon TLE92783BQXV33XUMA1 is an automotive-grade body system IC that integrates a single-output voltage regulator delivering a fixed 3.3 V rail from a wide input range of 4.5 V to 28 V. It is designed for converter and automotive body electronics applications where a regulated 3.3 V supply is needed for an MCU, sensor, or transceiver load.
Input range and output rail — what drives the BOM fit
The 4.5 V to 28 V input range covers 12 V and 24 V automotive systems, including cold-crank dips down to 4.5 V and load-dump transients up to 28 V. The single 3.3 V output is a common rail for many automotive MCUs and CAN transceivers, so this part can serve as the primary supply regulator in a body controller or gateway module. No second output for 5 V or 1.8 V is provided — the BOM will need a separate LDO or DC-DC for those rails.
