Questions about the comparator LM293ADR, please help to answer.
1. There are two test conditions for response time in the specification. What is the main difference? Why is the time difference so big?
2. Does Overdrive mean overshoot? Or overloaded?
3. When used as hardware overcurrent protection of PFC (requires 1-2us reversal), which test method should be referred to?
4. When used for hardware overcurrent, replace LM293 with other general-purpose comparators, will it affect the protection current value? As shown below
