SBAS901C July 2018 – October 2020 REF34-Q1
In ADAS applications it is important to have a low quiescent current when the automotive application does not require the ADAS system to be in use. This creates a need for a low standby power so the battery life is preserved but there is also need for the system to still be readily available to start-up with minimal delays. In such situations the MCU and other systems will go into a standby mode to ensure that the power consumption is lowered to the absolute minimum. The REF3425-Q1 offers an enable pin that can be controlled by the MCU to activate shutdown mode with causes the REF3425-Q1 to go into stand by and consume 3 μA (maximum) and allow for a longer battery life.
