TPS65217C and AM335X VOL and VIL mismatching

Manoj Agarwal

Other Parts Discussed in Thread: TPS65217

I am using TPS65217C and Am335X. I was doing DC analysis for IO voltage level compatibility. I found that

MPU : VOL is 0.45 and TPS65217 : VIL is 0.4V. As per voltage mentioned VOL < VIL is not satisfied. So let me know how this will work.

Hi Manoj,

The 0.45V is the maximum output value of VOL on the AM335x, so typical should be a little lower.

Realistically, the PMIC should recognize the logic low before it reaches 0.4V, but the exact thresholds are not defined for each pin.
