TIDA-00346 Reference Design

Texas Instruments

Cost-optimized power supply solution for entry-level core application processor-based ADAS systems

Description

The TIDA-00346 design provides the power supply rails necessary for typical  entry-level application processors in automotive advanced driver assistance systems (ADAS) applications.  The design uses several individual DC/DC voltage regulators as well as load switches and linear regulators (LDOs) to provide fixed-supply voltages to the processing cores and other functions of the system-on-a-chip (SoC). Additional rails for DDR memory supply and termination and a CAN Transceiver are also implemented. Two LM3880 simple power sequencers provide power up and power down sequencing.  The design is optimized for automotive applications and can operate with input voltages from 4V to 18V (transients up to 40V).
