TIDA-00805 Automotive Off-Battery Processor Power Reference Design for ADAS and Infotainment | TI.com
TIDA-00805: The TIDA-00805 reference design is an off-battery automotive power solution targeting processors in advanced driver assistance systems (ADAS) like surround view, front camera and driver monitoring, as well as infotainment systems such as cluster and head unit. The design operates directly from a 3.9 to 40V car battery input and provides all supply rails for the application processor, Controller Area Network (CAN), input/output interfaces and double data rate (DDR) memory.

TIDA-00801: The TIDA-00801 reference design is a full off-battery to point of load power solution supporting input voltages as low as 2V. It uses the Boost plus Buck DC/DC regulator TPS43330A-Q1 supporting an input voltage range of 2V to 40V and allowing the design to support not only start-stop but also cold crank conditions. The TPS659039-Q1 integrated power management IC supplies point of load power to an application processor such as the TDA2x/DRA7xx. Also included is a 5V/4A load switch, the TPS22965-Q1, and a linear regulator TPS51200-Q1 for DDR termination supply. Benefits: Supports cold and warm cranking, supports modern processors sequencing needs without further logic, supports peripherals and is a small form-factor, low system-cost solution.
Cost-optimized power supply solution for entry-level core application processor-based ADAS systems
TIDA-00346: 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).
