Part Number: TIDA-01541 Other Parts Discussed in Thread: LAUNCHXL-F28379D , Tool/software: Code Composer Studio Hi,
I'm doing a project similar to TIDA-01541 using LAUNCHXL-F28379D, and I nearly finish the hardware design, but there is still the sofware…
Part Number: TIDA-01541 Other Parts Discussed in Thread: AMC1311 , In TIDA-01541, AMC1311DWVR parts have 3.3V on VDD1. According to datasheet, AMC1311 B parts can use 3.3V, but the base AMC1311 requires 5V for VDD1.
Part Number: TIDA-01541 Other Parts Discussed in Thread: AMC1301 HI!
The motor current control loop is generally equal to the switching frequency. Sometimes it can be twice the switching frequency.The switching frequency of IGBT module is generally less…
Part Number: TIDA-01541 Other Parts Discussed in Thread: AMC1311 , Hello,
I am trying to understand the input circuitry on the two AMC1311 parts (U12 and U15) used in TIDA-01541. In both cases, the SHTDN pin (pin 3) is connected to part of the input differential…
Part Number: AMC1311 Other Parts Discussed in Thread: TIDA-01541 , , OPA211 Dear all,
I am using AMC1311B isolation amplifier for DC link voltage sensing in motor drive application. At No load to motor, DC link measurement is linear to actual values. However…
Hi Luuk,
The INA138 floating circuit will not work well as an inline current sensor, because it is unidirectional. There are circuit examples in the datasheet for bidirectional current sensing. You might be able to adapt them similarly into floating ones…
Hi Ahsan,
Apologies for the delayed response. With this indirect input voltage sensing method, any leakage in the transformer will impact the resulting voltage at J5. It is not a precise method for sensing the input voltage.
If a more precise is needed…
Hello Cagdas,
Thank you for looking into our reference design. In TIDA-01540, AMC1301 is being used for phase current measurement and AMC1311 is used for dc voltage and temp sensing. You have observed correctly that pinout of AMC1311 shown in schematics…
