5. Pin Description Table 5.1 Pin Description PIN Name Description
Enable input. Active high. EN This function turns on the output as an enable signal. Current limit set input. A resistor between ILIM terminal and GND sets the current limit. ILIM Please do not apply external voltage FLAG Open drain signal output. Outputs the status of a specific protection operation. MODE switching. MODE The fault response is auto-retry type at high input. When the input is low or open, the fault response is latch type. VIN Supply input. Input the power switch and the supply voltage for the device. GND Ground VOUT Output. Output of the power switch.
