3.2 Enable and Disable

VIN≥10.3V puts SR_UVLOb above the VTH_SR_UVLOb_RISING threshold to enable the device. Voltages at the monitored rails were already in regulation when enable occured.

VIN≤8.5V puts SR_UVLOb below the VTH_SR_UVLOb_FALLING threshold to disable the device. Voltages at the monitored rails were in regulation during this test.
