8.2 Functional Block Diagram
8.3 Feature Description
8.3.1 FAULT Response
The device features an active-low, open-drain fault output. FAULT goes low when there is a fault condition. Fault
detection includes overtemperature, overcurrent, or overvoltage on VBUS, DP_IN and DM_IN. Connect a 10-kΩ
pullup resistor from FAULT to IN.
Table 1 summarizes the conditions that generate a fault and actions taken by the device.
