Part Number: LMP8645HV Other Parts Discussed in Thread: INA181 I wanted to experiment the LMP8645HV with a current measurement on a 48V power supply (the LMP8645HV is powered by +12V). When I vary the load the function is correct. However, when I disconnect…
Other Parts Discussed in Thread: LMP8645HV Hi,
there is a problem in our power supply in case of short circuit: the LMP8645HV (that senses the output current) is subjected to high differential voltage drop of 50V over Rs for a short while. What could…

Team,
In the photo of an LMP8645HV above, I'm not able to find a marking on the device that indicates orientation (pin 1). How is this identified on the physical device and where is that documented in the…
Part Number: TPS4811-Q1 Other Parts Discussed in Thread: LMP8645HV Tool/software: Hy,
I use a TPS48110 in a charge / discharge circuit for ION battery (see the attachment). OP_OV signal is not used, R6 is NOT mounted.
Looking at data-sheet, Figure…
Hello Jared, We do not have a pin-to-pin device with the exact same functionality and higher gain. However, the INA282 does come in an SOIC-8 D package with higher gain options and comparable or in some aspects better performance at the price of lower…
Other Parts Discussed in Thread: LMP8645HV , TPS54260 Dear TI team,
We are using TPS54260 with LMP8645HV as constant current source to charge a capacitor bank of 100mF with a peak current limit of 3A. Once the capacitor bank is charged, the current…
Hey Fabio,
The highest bandwidth current-sense amplifiers are the INA139/INA169, LMP8645HV, or LMP8640 and this can be determined with product selection tool online. The BW is not constant for INA139 with RL=1kΩ because it is operating in unity gain…
Hi,

Although I still need to use power line to transmit the data about the motor's speed or something else to control the motor.
So, do I need to buy a new device or any software I can use?
if you wish implement motor control…
