Can this sensor be connected directly to the psi5 port of the ecu

Dear Jhonemagee,

if your ECU has the PSI5 1.3 version, then yes.

Alternatively you can use our SEN-PSI5-ADAPTER

Dear JozefKozon,

Is the No. 3 pin IDATA of the chip output a current signal or a voltage signal?

Dear Jhonemagee,

please refer to the section 4.2.1.2 in the MMA51xxKW datasheet. The IDATA pin sources current. So it is a current pin.

Dear JozefKozon,

We ECU has the PSI5 1.3 version.  I wonder if this sensor can directly implement synchronous parallel mode without PHY. Just like the picture says

Dear Jhonemagee,

the recommended connection for the MMA51xx sensors is daisy chain as in the Figure 25. in the MMA51xxKW datasheet. It is similar to your bus configuration with added discrete components. The recommended external components are in the Table below the Figure 1.

Please also refer to this document, where an application example for PSI5-P10P-500/3L compatible sensors is described.
