Frequently asked questions
Is TPS3839K33DBZR active low or active high?
The reset output is active low. The output goes low when the supply voltage drops below the 2.93V threshold and remains low for the 120ms minimum timeout after the supply recovers.
What is the output type of TPS3839K33DBZR?
The output is push-pull, totem pole. This means it can both source and sink current, eliminating the need for an external pull-up resistor to the supply rail.
