Part Number: LM74500-Q1 Other Parts Discussed in Thread: LM74700-EP , LM74700-Q1 Hi Experts, Good day.
This is regarding the LM74500-Q1 component. You recommended that we use two unidirectional TVS devices at the input of the circuit for voltages that exceed…
Part Number: LM74500-Q1 Hi, I need to evaluate LM74500 based power filter design in my project for this i would need to simulate the ckt with ISO pulses generstor in LTSpice
LM74500 is an encrypted model hence, can't be imported
Please suggest how…
Part Number: LM74500-Q1 Hello Team
The time delay for Enable pin low to high to gate driver enable is provided in the datasheet. We also require the information on time required for the Gate pin to go low in case of Enable pin toggled from HIgh to Low…
Part Number: LM74500-Q1 Hi team,
Could you help explain what POR falling threshold means? Can customer use it as a UV protection for VS?
When they apply KL30 to VS (CH1 in yellow) and measure the VGS as VS drops, they found gate turns off threshold is…
Part Number: LM74500-Q1 Other Parts Discussed in Thread: LM74700-Q1 Hello TI expert,
Here are some questions about Device temperature grade 1 in datasheet of LM74500-Q1/LM74700-Q1 .
Background: The maximum ambient temperature of LM74500-Q1/LM74700-Q1 is…
Part Number: LM74500-Q1 Dear team,
We have a VSOURCE POR falling threshold. Do we have the glitch time for this threshold? My customer feedbacks that they make a simulation, when they set Vsource<1V for almost 20us, the gate pin doesn't pull low yet.…
Part Number: LM74500-Q1 Dear team,
I noticed that electrical characteristics was tested under Tj=-40C to 125C. It means that the electrical characteristics may change during Tj=125C to 150C, right? If so, could you please tell me why our specs can't cover…
Part Number: LM74500-Q1 Dear Sirs,
Here is my customer schematics. They just use it for reverse 48V input protection.
The questions are:
1. Does LM74500-Q1 suit switching power source input protection since the datasheet shows the input source is from…
Part Number: LM74500-Q1 Dear Sir/Ms.
It is stated in the specification that LM74500 can pass the ISO76730 pulse 1 test. For the 12V system, the input load is 12V/2.5A~3A. The waveform of the test is as shown in the figure below.
The customer's terminal…
Part Number: LM7481-Q1 Other Parts Discussed in Thread: LM74500-Q1 , LM74501-Q1 , LM74502-Q1 Hi
Could you help suggest a reverse polarity protection IC for the input terminal.
The requirements are as follows:
Input power: 1000w Input
voltage: 8~24v
Input…
