Tool/software:
I'm trying to control the output of two TPS2663s in one system and I'm checking their operation.
1. Basic configuration
If you measure the input voltage of each load, the characteristics are roughly like that.
2. Remove one cable
I understand the voltage characteristics input to each load.
3. Control from MCU without removing cables
When controlling the output by setting the SHDN pin with the MCU, the output of the TPS2663 should not be generated, but the input voltage characteristics for each load appear as shown above.
PG pin and FLT pin are working normally.
If I remove the output cable of the SHDN TPS2663 in that state, the output is measured as 0V.
It seemed like it would be the same as the 2nd configuration result, so why did that characteristic appear?
