Part Number: TPS2660
the TPS26600 has specified in the datasheet that the SHDN pin will be activated once the voltage will be in the range of 0.55-0.94 V.
If I want to get out from shout down what would be the voltage that will let me start the device again?
is it the range of 2-3.4V?
What does it means the parameter V (SHDN) Output voltage?
In reply to Karikalan Selvaraj:
is it what you have mentioned specified in the datasheet?
Device will recover and start again if the voltage goes above 1.2V (across temperature) due to hysteresis. SHDNb has internal week pull up. SHDNb output voltage is the voltage when the pin is left floating or 0.1uA leak.
What does it means the parameter Output voltage specified in the table above?
In reply to Sunset:
As SHDNb pin is controlled by digital, datasheet does not have hysterisys mentioned, but it 20mV typical. Across temperature hys increases and 1.2V is when device restarts across temperature.
Output voltage specified in electrical characteristics table is SHDNb pin voltage when the pin is left floating. (internal pullup pulls this pin to 2.7V typical)
Please refer to figure 48 of the datasheet for the internal pullup diagram.
thanks for the additional information.
