5.4 Output Undervoltage Protection Test
Use the following instructions to perform output undervoltage protection test:
-
Set dual polarity regulated power supply to +15 V : 0 V : –15 V and apply the power at connector J2
-
Connect a load of 3 kΩ between I_IN_1 and AGND_1 at connector J1
-
Apply a voltage of 0 V at I_OUT_1 and gradually decrease the voltage to –15.4 V to trigger the output undervoltage fault
-
Observe the waveforms using an oscilloscope
