Table 4-3. Jumper and LED Descriptions
Jumper Label Description
J4, J10 MODE
Overload Response Setting
Leaving J4 OPEN sets MODE = OPEN
1–2 Position connects MODE pin to GND
2–3 Position connects 180 kΩ from MODE pin to GND
J5, J11 EN
EN has internal pullup and it can be left floating to enable the device
Pull EN low to turn off the device
J6 R_burden
Jumper to select burden resistor
1–2 Position connects 49.9 Ω as burden resistor
3–4 Position connects 100 Ω as burden resistor
5–6 Position connects 249 Ω as burden resistor
Leave J6 OPEN to connect load externally
J7 –VS1 Install to use U1 in single supply configuration
J12 –VS2 Install to use U3 in single supply configuration
J14 Feedback selection jumper
Jumper to select the feedback point
1–2 Position does not compensation the voltage drop in the eFuse
2–3 Position compensates the voltage drop in the eFuse
