Part Number: LMP8481 Tool/software: Hello TI team, I am currently working on Battery Management System(BMS) project and using the LMP8481MM high-side current sense amplifier(Bi-directional) for current measurement. However, i am facing repeated current…
Part Number: LMP8481-Q1 Other Parts Discussed in Thread: LMP8481 Tool/software: I am using S version of the part. According to my circuit design at zero current, offset value is suppose to be 660mV(+- 5mV). I am achieving this in 999 out of 1000. But…
Part Number: LMP8481 Tool/software: Hello-
I am using the -S and -T versions of the LMP8481 current sense amplifier.
I am using TI's "Current Sense Amplifier Comparison and Error Calculator" https://www.ti.com/tool/CS-AMPLIFIER-ERROR-TOOL spreadsheet…
Part Number: LMP8481 Hi Experts,
Seeking your assistance on this query from Cx:
Rsense =0.03 ohm
If I try the first 0.03-ohm Rsense, 12v supply, and load current below 0.5A I get the expected LMP Vout according to the equation: VOUT = (VRSP – VRSN…
Part Number: LMP8481 Other Parts Discussed in Thread: LMP8480 Hello there,
I'm considering to replace LMP8480 with LMP8481 due to the stock. I just want to confirm : if I connects NC pins (pin 6 and 7) into GND (pin 4) with LMP8480, can I directly drop…
Part Number: LMP8481 In my board the LMP8481 is not giving the proper output. From the data sheet the sense voltage can be found from vout voltage by the equation ( vsense = vout / gain). And I am using the LMP8481 H variant of the IC. So for a 2A current…
Part Number: LMP8481-Q1 Hi Team,
While reviewing the LMP8481-Q1 datasheet, I noticed what appears to be a typo on page 11:
I believe that value should be 0.1 µF as listed in other diagrams within this datasheet. I’m not sure if this error is in…
Part Number: LMP8481 The following is not understandable in LMP8481 DATASHEET 8.1.1 Theory of Operation. Can you explain it? Thank you!
"Internally, the voltage on each input pin is converted to a current by the internal precision thin-film input resistors…
Part Number: LMP8481 At 5V and low Rload, gain is low. Vcc is connected to Rsense as in your typical application schematic, page 1 of datasheet.
My schematic Rsense= 0.1 ohm, RefA and RefB are grounded, unidirectional current flow
Typical Iload= 1A…
