7.4.3 Standby and Normal Mode

The LP5814I enters STANDBY mode when CHIP_EN = 0 or NORMAL mode when CHIP_EN = 1 after exiting from , INSTANT BLINKING mode or THERMAL SHUTDOWN mode.

While staying in STANDBY or NORMAL mode,

  • when instant blinking function is not disabled (INSTABLINK_DIS = 0), the LP5814I enters INSTANT BLINKING mode after the 300ms blank time as described in Instant Blinking.
  • when Enter Shutdown Method is applied, the LP5814I enters SHUTDOWN mode. The Enter Shutdown Method is described in Shutdown Mode.
  • when the junction temperature of the LP5814I rises above the thermal shutdown threshold TSD, the LP5814I turns off all output channels and enters THERMAL SHUTDOWN mode.
