Other Parts Discussed in Thread: TIDA-00445 , INA240 , TMCS1100 , TMCS1101 , AMC1302 , AMC3301 , OPA37 Hi tech support
Currently i am designing in line current motor measurement in three phase inverter with DC supply voltage 350VAC and expected VL-L 220Vrms…
Part Number: TIDA-00445 Other Parts Discussed in Thread: AMC1200 Hi team,
Looking into the schematic, the sensing point (i.e. J1) is connected to ground, making the common mode voltage at ground. In this case, how is "High-Side Current Sense Circuit With…
Part Number: BQ34Z100-G1 Other Parts Discussed in Thread: TIDA-00445 , , OPA2376 Can I use TIDA-00445 reference design as a replacement for current sensor in BQ34Z100-G1, for high current applications?
If yes, then how low can be the shunt resistor value…
Thanks for the clarification. Shall we adopt same as TIDA00555 design. The only difference we will create star point in the board.
Also is there any specific advantage having an isolated power supply for shunt current sensing method??
Yes, both of these measurement accuracy targets are possible, however there are several factors to consider. Here are some measured results for a +/-85A sweep that meet these targets. Please note that only offset calibration was performed…
For DC current measurement
For DC voltage measurement
Please note that more…
Part Number: TIDA-00366 Other Parts Discussed in Thread: TIDA-00364 , , TIDA-00445 , TIDA-00316 , TMP235 Hello,
TIDA-00364 is a MOSFET based high current inverter from 48V DC Bus, much similar to my requirement of an inverter for a Synchronous Reluctance…
Part Number: LM4040-N Other Parts Discussed in Thread: TIDA-00445 Hello,
I am trying to use the LM4040BIM3-2.5 to generate dual polar power supply similar to the circuit described in TIDA-00445, and the circuit I am doing is shown below.
The normal input voltage range to the AMC1200 is +/-250 mV, with a supply voltage of 5 V. To implement a high side current sensing scheme, you would need to provide an isolated power rail that was floating above the high side return. You can…
