Figure 4: Chained Operation
Notes to Figure 4:
1. Connect NEXT_O to NEXT_IN on device at end of chain.
2. Tie all nFAULT_x pins of all chained devices together. When fault is detected in any device, the device
pulls the nFAULT line low, triggering sequential power down starting with the end device. This is
released by EN low until FAULT is cleared.
3. Tie NEXT_O to EN of following device. Tie NEXT_IN to OE_O of following device.
