Tool/software:
Hi Folks,
I am currently using a synchronous LED driver with the MPN TPS92200D1DDC. When calculating the noise margin between the processor and LED driver at logic low, I obtained a negative value of -0.33V.
Processor VOL(max) is 0.66V.
LED Driver VIL(max) is 0.3V.
The margin (VIL - VOL) is -0.33V.
VIL refers to Voltage Input Low, and VOL refers to Voltage Output Low.
I would appreciate your comments on whether the negative noise margin will affect the design or not.
