Part Number: LM74502 Hi,
I am using LM74502 for load dump protection. In the evaluation board, there is an RC block for the FET.
So should I place these components for my project?
Best regards.
Part Number: LM74502 Hello,
I am using LM74502 in our design as input reverse protection. Below is part of the schematics. In my test, 24V DC is the input voltage, there is no load connected to the output.
I found a strange behavior on output voltage…
Part Number: LM74502 Hello,
I am using LM74502 in the circuit as reverse protection.
Below is the schematic of LM74502 section. There is a TVS (SMA24CA-13-F) on VIN, there is no output capacitor for VOUT (VIN1_P1 to VIN1_P4 in the schematics) on the board…
Part Number: LM74502 I am wondering what the common failure modes are for LM74502DDFR and how it can be effected by FETs that have also failed (bridging across G-S, D-S failing open etc)?
Cheers!
Part Number: LM74502 We're building a 200A 50V switch for a battery system with inverter. See enclosed schematic.
Can a LM74502 have sufficient drive to run these FETs in parallel, or do I need the LM74052H?
DO I need any capacitors in the SRC or…

Hi,
In my design, I am using LM74502 for load dump protection. My circuit is attached
When the Vin is around 4.8V the output voltage that supplies the SMPS goes too low. The scopes are attached…
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 …

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 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…
