Other Parts Discussed in Thread: TDC1000, PGA460, TUSS4470, , TDC7200
I well know TI's ultrasonic sensor ICs, such as PGA460 and TDC1000. Those ICs can be programmed via SPI port with the help of an MSP430 or a C2000 (or any other MCU). Some are direct drive, and some others are the transformer drive types.
Recently I got familiar with MSP430 ultrasonic sensing mictrocontrollers, which are designed for ultrasonic application-specific purposes.
I want to know:
1-if they have any extra benefits in comparison with ICs like PGA460, TDC1000, and TUSS4470?
2-I think these MCUs have not any output driver submodule and are appropriate for transducers using standard MCU voltage levels (3v). I need to drive a 100 v transducer so that I'm curious to know whether any of MSP430 Ultrasonic MCUs provides an output driver submodule or not? If no, we should consider an independent circuit for driving a 100v transducer (MOSFET gate driver + Transformer).
Therefore taking into account the BOM, I think using a TUSS4470 + a low price MCU to program it could be more cost effective because TUSS4470 has an output driver submodule.
Does the MSP430 Ultrasonic MCU Design team have any other idea?
