Ti Tuesday High Side Current Sensing With The Ti Lmp8481 H Youtube For this week's ti tuesday i am looking at a chip. the ti lmp8481 precision high side current sensor.it is capable of a whopping 4.5 76v operation and the co. This high side, current sensing solution uses a current sense amplifier, a comparator with an integrated reference and a p channel mosfet to create an over current latch circuit. when a load current greater than 200 ma is detected, the circuit disconnects the system from its power source.
Lmp8481 Datasheet Pdf Texas Instruments The lmp8480 and lmp8481 are single supply, high side current sense amplifiers with available fixed gains of x20, x60 and x100. the power supply range is 4.5 v to 76 v, and the common mode input voltage range is capable of 4.0 v to 76 v operation. the supply voltage and common mode range are completely independent of each other, which causes the. 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) * av ) vref. then when i changed the power supply to 42v and load current 2a i.
