Part Number: LM7480-Q1
Hello, When following the datasheet for LM7480-Q1, 10.3 200-V Unsuppressed Load Dump Protection Application - I'm wondering if I should add a TVS to the voltage output of the 200V example such that I can guarantee a limit in transient…
Part Number: LM7480-Q1 Tool/software: Hi
I have a problem with the LM7480-Q1 failing to switch on the external transistors Q1 and Q2 in the circuit below.
The measured voltage on VS (pin 10) is approximately 3V referenced to GND. Input voltage is…
Part Number: LM7480-Q1 Hi
We have implemented the below circuit and we are testing our design. The current consumption on 24V is around 80A. We are seeing this Zener diode D4 getting heated up. What could be the reason? We have given 24V input through…
Part Number: LM7480-Q1 Other Parts Discussed in Thread: LM74800-Q1 Hi
We are planning to use LM74800QDRRRQ1 for our Electro magnetic ECU board which is based on 24V @200A. The maximum possible current is around 150A. We want to know if the selection…
Part Number: LM7480-Q1 Is there any further documentation on using ideal diode controllers for power MUXing / power prioritization? I have only found the application brief article titled "Priority Power Mux Using Ideal Diodes in Automotive Zonal Modules…
Part Number: LM7480-Q1 Other Parts Discussed in Thread: TIDA-010242 Hi, a new version of MIL-STD-1275E to MIL-STD-1275F has been published recently. The TIDA-010242 reference design is based on the MIL-STD-1275E standard. What adjustments will be needed…
Part Number: LM7480-Q1 Tool/software: Hello,
we want to use the LM7480-Q1 to switch the 24V Supply for the Load on and off. On the PCB we have to power supply 15V and the 24V supply that we want to switch. the 15V supply is bufferd in a short curcuit…
Part Number: LM7480-Q1 In the datasheet for this part in figure 9-3 "Inrush Current Limiting" there is an R1 resistor in series with the C(dVdT). What is the process used in the selection of this resistor? I did not see it mentioned in the datasheet while…
