Inspect the IC for visible damage. Check for Interference: Examine the environment for potential sources of noise or EMI . Use an oscilloscope to identify any unwanted signals on the reset line. Improve Power Supply Decoupling: Add decoupling capacitors near the power supply pins to reduce fluctuations in the power rail.By following this troubleshooting guide, you should be able to identify and resolve the issue preventing your TPS3838K33DBVR from holding the reset as expected. If the problem persists even after these checks, it may be worth consulting the datasheet or seeking support from the manufacturer for more advanced diagnostics.
