Part Number: LM74900-Q1 Other Parts Discussed in Thread: LM74900 Dear TI experts,
I used two LM74900 chips on a circuit board I made myself to form an o-ring circuit to power the entire board. Below is my detailed schematic diagram.
However, I encountered…
Part Number: LM74900-Q1
Tool/software:
I finally have more boards to check and now I am not getting anything on the Secondary except for the fault light.
I am getting 60 volts on VCAP on the Secondary, and I am not sure where that is coming from…
Part Number: LM74900-Q1 Other Parts Discussed in Thread: LM74900 Hi Team,
Can you share unencrypted SPICE model for the part number LM74900QRGERQ1 which is compatible in SIMetrix Simulation platform?
Part Number: LM74900-Q1 Tool/software: Dear experts,
We are using 2 LM74900-Q1 chips to design the ORing circuit. The following is our schematic diagram. Can you help us review it? In addition, is there a schematic checklist of the chip for our reference…
Part Number: LM749X0-CALC Other Parts Discussed in Thread: LM74900-Q1 Hello Team,
I have used the LM74900-Q1 PSpice Transient Model in PSPICE for TI simulation platform for our application circuit. While simulating i got error addressign the subcircuit…
Part Number: LM74900-Q1 Other Parts Discussed in Thread: LM74900 Dear Experts,
Here is our circuit schematic diagram. We found during testing that the voltage of VBAT_12VSB drops to around 5V when connected to a load, with a voltage drop of nearly 7V…
Part Number: LM74900-Q1 Other Parts Discussed in Thread: TPS1HB08-Q1 Hi,
is it possible to put a diode on the gnd path of the IC to protect it from negative voltages on the output lower than -1 V? On my application I cannot put an antiparallel diode…
Part Number: LM74900-Q1 Tool/software: I am using Orcad PSpice to simulate ISO16750-2 transients in an LM74900-Q1 application circuit.
I wanted to import a txt file with voltage waveform from the ISO16750-2 4-6-4 Test A as a PWL source and apply it…
Part Number: LM74900-Q1 Dear Team,
Good day.
We are looking for a surge-protection circuit that can protect the system against input surge voltages up to ±80 V for 100 µs and ±40 V continuous for 1 minute, without causing any damage to the system…
