Other variations:

In a Host MCU controlled system, EN/UVLO or OVLO can also be driven from the host GPIO to control the device.

ILM pin can be connected to the MCU ADC input for current monitoring purpose.

Note:

TI recommends to keep parasitic capacitance on the ILM pin below 50 pF to ensure stable operation.
