Part Number: LMP8640HV Other Parts Discussed in Thread: LMP8640 Tool/software: Hi Ti experts,
My customer uses LMP8640 in OBC for current sensing. They found it has wrong current sensing value. When the actual load current is 30A, it can only get the…
Part Number: LMP8640HV Other Parts Discussed in Thread: LMP8640 Tool/software: Dear Team,
we are using the IC for Current sensing, Observed output is not stable. kindly check the below circuit.
please suggest if any changes required.
Inputs: …
Part Number: LMP8640HV Other Parts Discussed in Thread: LMP8640 We use LMP8640HVMKE-H/NOPB in sensing current (upto 3A) on a 48V DC rail. The sense resistor used is 8 mOhm to minimize the dc drop and power.
At low values of currents (~75mA), some of…
Hello John, Thanks for considering to use Texas Instruments. This transient you see from the inductive kickback, how large is it? If it is greater than -6V, you likely have damaged the LMP8640HV. Below is a table from the datasheet that specifies the…
Part Number: LMP8640HV-HEVAL Other Parts Discussed in Thread: LMP8640 Hello E2E,
Our customer bought LMP8640HV-HEVAL. However, non HV version is mounted in EVM.
Is this the correct EVM? Can this EVM tolerate 60V input?
Regards, ACGUY

Part Number: LMP8640HV I have a customer using LMP8640HV-F.
What's the max current the amp can source under the following conditions:
Sensing 20A through a .5mOhm shunt resistor
3.3V supply voltage.
The output loading is an RC filter into ADC…
Part Number: LMP8640HV Hi,
My customer would like to use the LMP8640HV for a 60V application but they need to meet the IPC-2221B standard for conductor clearance. If I understand correctly, they would need 23.62 mils of clearance between external conductors…
Part Number: LMP8640HV Hello,
I will like to know please what the information on the NAMING OF LMP8640HV can be found.
I have looked in the datasheet and there is nothing about what the MKE prefix stands for.
I am particularly interested in the…
Part Number: LMP8640HV Other Parts Discussed in Thread: INA190 , INA225 Hi,
I am using the LMP8640HV IC for current sensing upto 5A with gain of 100. The issue is when no input voltage is applied to the op-amp, the output voltage is referenced at around…
