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 Other Parts Discussed in Thread: LM7480-Q1 I am using two of them to decide what source powers the board. One is a Wire to board terminal. The other is USBC.
We don't want the main rail to feed back into the USB connector. It can…
Part Number: LM74502 Hi
I would like to replace an electromechanical relay by a back to back n-mosfet configuration.
Could you tell me if this schematics will work?
Furthermore is the LM74502 also suitable for 48V application in PWM mode? For example…
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…
Part Number: LM74502-Q1 Other Parts Discussed in Thread: LM74502 Hello TI expert,
Regarding LM74502 datasheet page 16, it mention about minimum required capacitance. The output capacitor is 220uF.
1. What is the reason to have this 220uF? 2. If my total…
Part Number: LM74502 Hi team,
Is there any design calculator (excel) available for LM74502? Specifically to calculator min and max UVLO and OVP including resistor tolerance, temperature and other variations.
Of course this can be calculated manually but…
Part Number: LM74502 Dear TI support team
The LM74502EVM user's guide shows on the schematic on page 6 the elements Q5, D1 and R1, but there is no explanation about this optional circuit, also in the datasheet this option is not mentioned at all. …
