5.2 Output Short-Circuit Test
Use the following instructions to perform an output short-circuit test on TPS26610 (U1):
- Set the jumper setting J4 in 2–3 position to set MODE = 180 kΩ
- Open jumper J6
- Set dual polarity regulated power supply to +15 V : 0 V : –15 V and apply the power at connector J2
- Apply a voltage of 12 V at I_IN_1
- Short the output of the device for example, I_OUT_1 to AGND_1 with a shorter cable
- Observe the waveforms using an oscilloscope
Figure 5-5 and Figure 5-6 show test waveforms of output hot-short on the TPS2661 eFuse evaluation board.
