Other Parts Discussed in Thread: LM139-SP,
Customer has several questions about EN-pin.
1. What is the state of EN-pin during VIN = PVIN = 0V?
2. Can the EN pin be controlled by connecting the outputs of the logic IC if the threshold voltage: 1.13 to 1.18V and current: 3.2uA are satisfied?
Or do they need to use open-drain or open-collector output logic(like LM139-SP) to interface with the pin?
3. How should they deal with PWRGD pin when the pin is unused?
