Tool/software:
The main question here is about when and how the TIMER capacitor in the TPS2301 charges and discharges based on the device’s internal logic. In the provided specification, the TIMER capacitor begins charging upon detecting an overcurrent event, and when it reaches 0.5 volts, it triggers an overcurrent shutdown of the system. The capacitor discharges when power is cycled or the Enable pin is toggled. This behavior is clear in typical conditions.
However, what remains unclear is how the TIMER capacitor behaves if there is a very brief , short or a noisy overcurrent detection event, such as a short-duration spike (possibly noise), that occurs for much less time than it would take to fully charge the capacitor to 0.5 volts.
Specifically: Does the TIMER capacitor automatically discharge after the short overcurrent event ends so next time TIMER cap can restart from zero volts? Or the capacitor maintains its residual charge and starts charging from the this condition (not zero volts) when the next event occurs either real over current or another noisy very fast one
In summary, the question is about the behavior of the TIMER capacitor in response to short overcurrent events regarding discharge logic?
