I am in a design phase of TPMS Board. I have chosen this part FXTH8715116T1 but it can support only minimum pressure sensing range of 100kpa ( ie 14.5 psi). I need min 4 psi ( ie.27.5 kpa) for my application . kindly suggest any external sensor which can support that range and also integrate with that part.
Thanks in advance.
Hi Balajy,
I would recommend the MP3H6115A which is an integrated 3V analog absolute pressure sensor operating in the range of 15kPa to 115kPa. It has temperature compensation, calibration and amplifier circuitry on–chip and its output voltage for full rated pressure is typically 2.82V. You can connect its output (pin #4) to either PTA0 (AD3) or PTA1 (AD4) pins of the FXTH8715116T1 and use the corresponding routines (TPMS_READ_V0 or TPMS_READ_V1) to read the output voltage of the MP3H6115A.
I hope it helps.
Best regards,
Tomas

Thanks for your reply Tomas,
I forgot to add my maximum requirement in the previous conversation. My input requirement range is 4 to 45 psi.But the above part can support max 16.5psi only. can you please suggest any other part which can support the above requirement?
whether this sensor can meet the software compatibility with FXTH8715116T1? kindly provide your suggestion.
Thanks in advance.
Thanks Tomas, I will look into it.
