If OV pin is connected to VIN, how is it then protected during Reverse Polarity when the OV voltage divider will create a negative voltage on the pin?
Part Number: LM74502-Q1 I'm using the LM74502-Q1 in fig. 10-2 "Typical 24-V Battery Protection with Two Uni-Directional TVS" I have OV with 270K - 10K & UVLO with 680K - 43K This gives me thresholds:
UVLO Falling 19.17V UVLO Rising 21…

Hi,
For my design, I will use LM74502-Q1 IC that protects my circuit for 160V load dump (ISO 16750-2. Us = 160).
I will not use reverse voltage protection feature…
Part Number: LM74502-Q1 Other Parts Discussed in Thread: LM7480-Q1 , LM74502 Hi,
I designed this circuit to protect the SMPS from 160V load dump. The circuit is attached.
1-Is this circuit suitable for 160V load dump protection? (VOUT clamping)
2-Is …
Part Number: LM74502-Q1 Hi
Can this MOSFET SiA108DJ https://www.vishay.com/docs/77827/sia108dj.pdf be used for this 24V protection circuit? or any other MOSFET suggestion with smaller size?
also can this circuit pass ISO7637-2 3a and 3b test pulse up to…
