Part Number: LM25149-Q1 Tool/software: Hi Team,
Looking at the LM25149-Q1 datasheet, the stated overcurrent Vcs-th threshold tolerance is 49mV min to 73mV max. In the Typical characteristics section Figure 7-18 shows the Current sense threshold vs temperature…
Part Number: BQ40Z80 Other Parts Discussed in Thread: LM25149 Tool/software: Hi Team, We are in the process of developing a board that combines both the BQ40Z80 and the LM25149 IC for a battery BMS+Charger application with AEF. The specs are as follows…
Hello,
I do not have a 0.8V source in my possession. My design is identical to LM25149-Q1EVM-2100, but with components for 440 kHz switching frequency.
The datasheet says tie CNFG to GND to disable AEF. But I am still getting the same EMI results.
Part Number: LM25149-Q1 Other Parts Discussed in Thread: LM25149 , LM25148 , , LM25148-Q1 Tool/software: Hi everyone,
I am trying to simulated LM25149-Q using WEBbench tool but it is showing the "simulation not enabled for this design". So, please let me…
Part Number: LM25149-Q1 Other Parts Discussed in Thread: LM25148-Q1 , Tool/software: Hi,
I'd like to go as low as 200 kHz (switching frequency). 5 V, 2 A output. I do not have any specific requirments when it comes to peak-to-peak current and such. What…
Part Number: LM25149-Q1 Tool/software: Hi,
I have a few questions regarding the LM25149-Q1.
Is DRSS disabled by placing a 24,9k or 29,9k ohm resistor at CNFG? The application examples in the datasheet show a 24,9k ohm resistor and the table of configuration…
Part Number: LM25149-Q1 Hi Team We are planninng to use the LM25149-Q1 as a for 16.8V 5A CCCV Charger. I have the calculator and Webench design ready and i have a few doubts and the numbers are not matching on both the the quickstart tool and Webench. If…
Part Number: LM25149-Q1EVM-2100 Other Parts Discussed in Thread: LM25149 Tool/software: I am trying to figure out what I did to kill my LM25149-Q1EVM-2100.
I want to use the LM25149 as a battery charger for a 12 Volt SLA battery. For that I need an output…
