Part Number: EV2400
Hi,
I have tried but could not succeed in changing the I2C pull-up voltage from 3.3V to 1.8V. I have made following changes to EV2400EVM.
VPUV.2 is 3.3V with R38 as 10K
1. Changed R38 to 35K, VPUV.2 is 1.99V
2. Disconnected / lifted 6,7 pins of U14. Changed R38 - 56.2K and at C32 placed 28K. still noticed VPUV.2 is 1.99V
Can you please check and suggest on bringing voltage to 1.8V.
1. 
Regards,
Mani
