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…
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 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…
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…
