I received some questions from my customer about the fault pin assertion of TPS2557. I would appreciate if you could give us an advice about it.
Question1: Fault pin assert condition of TPS2557DRBT
Although the specification states that this device is asserted low when it is overheated or overcurrent, is it the only condition that is asserted low? Isn't it asserted low, for example, when input power is lost?
Question2: Temperature Derating Characteristics for several device
They want to know the temperature derating characteristics of the following devices. Where should I check to see if it follows the below conditions?
The customer has just reviewed all the specifications, and they are checking that there are no significant temperature characteristics, such as current output drop below 80% or a 5% output voltage drop happening at a high temperature of +85°C.
