Hi,
We are using TPS2121 for switching Main power and the Battery Power. Attached the circuit below for your reference.
Observed the the system is getting Reset/OFF during the Power switching from IN1 to IN2.
Tried with different the CSS values (100nF, 1uF & 10uF), but the behavior wise no change.
Tried removing the OV1 & OV2 voltage divider sections.
Also tried by changing the values R140 - 16.2K, R137 - 2K, R143 - 4.7K, R136 - 15K, but issue was still there.
Main power (12V)
Battery Power (6.9V to 8.4V)
Load current Max: 1.89A.
Please suggest what are we missing.
Regards,
Mahesh
