Use the following instructions to
perform output overvoltage 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 increase the
voltage to 15.3 V to trigger the output overvoltage fault
- Observe the waveforms using an oscilloscope
Figure 5-9 shows output
overvoltage protection response of TPS26610 on TPS2661EVM eFuse evaluation
board.
