Part Number: TCA9517-Q1
Hello Team,
I am using TCA9517 in automotive RTC application as a level shifter of I2C between controller and RTC chip, So VCCA=3.3V and VCCB=5V,
as per datasheet VIL at SDAB side is 0.4V Max, As below
The RTC chip which I am using from another manufacturer having below output specification,
In the low level output current it is mention output voltage is VOL=0.4V at IOLmin=3mA
Is this Output level ok for input of SDAB, or is it ok if I reduce pull up current form SDA pin to 1mA so that voltage drop from this RTC chip will also reduce ?
Is this allow in I2C to reduce IOL from 3mA, because in most of devices it is mention as minimum IOL = 3mA at 100KHz.
Thank you.
Best Regards,
Vaibhav Waman
