10.2.2.4 Enable Feature in ADAS

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.
