2.2 Device Operation Modes

The LMKDB1108 can be configured to start up in one of two modes during power-on/reset (POR). SBEN enable pin determines the mode of operation during power supply ramp up. Below are both the modes for the device:

  1. SMBus Mode Only (EVM default): When SBEN pin is set to low during the power up. SBI interface is disabled, output enable (OE) control is only accessible through the SMBus and OE control pins.
  2. SBI Mode: When SBEN pin is set to high during power up, SBI interface is enabled and the outputs can be controlled through SBI interface, as well as SMBus and OE control pins.
