Hi Tom,
I am unsure why + and - side will have difference. Go ahead with R and Zener and lets test. If it does not resolve, we can dive deeper.

Part Number: LM74502H Hi
Is it possible to use the LM74502H for PWM applications in the range of 1kHz?
I am looking for a simple gate driver IC which can go up to appx. 60V for simple relay replacement in HS configuration and is also capable to be used…
Part Number: LM74502H Hello team,
My customer is considering the below circuit and have a question on abs max voltage on SRC.
<Question>
The datasheet says SRC must not exceed VS voltage.
But when VIN turn off immediately and FET is switched off…
Part Number: LM74502H Can you review this schematic for any issues with enabling voltages or device drive? Logic inputs are 3.3V max.
It is designed to be a 200A switch for a 50-56V LFP battery system connected to a Sol-ark 15 inverter.
Can you also reply…
Part Number: LM74502H-Q1
Hi, My typical working voltage maximum is 60V but I need 100V 1us. I want to do this by separating the GND as in the picture and adding an extra TVS. Is this a correct use? (Power line is carrying over 100A, impossible to hold…
Part Number: LM74502H I'm experiencing inconsistent behaviour with a LM74502H configured as an input surge stopper, with UVLO.
The UVLO/EN pin is connected through a resistor divider to operate falling/rising at 1.14v/1.24v(nom) respectively. The…

Hi,
Regarding the LM74502H-Q1 device and this schematic;
1) Is this device suitable for automative oil/water pump application? 150W motor, 12V Battery, 13A rated with 40-50A peaks…
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 Lanxi Li,
The Gate driver of LM74502-Q1 is internally connected to VCAP by a PMOS internally when the gate driver is enabled. The PMOS resistance is very low in case of LM74502H-Q1 and hence has higher gate drive strength. So, you can expect the ripple…
