TPL0102 Tolerance

John Wallace1

I want to use the TPL0102 to program the SENSE threshold for the TPS3808G01. The goal is to achieve 0.1% resistor divider tolerance. In divider mode, is the TPL0102 capable of achieving 0.1% resistor divider tolerance?

John,

I've moved this post to the I2C forum where the TPL0102 is supported. I'm sure that someone will be able to find you an answer here.

Hi John,

I'm currently looking into this question for you.

Thank you,

Siby

Hi John,

We do not express the accuracy as a %, but as an LSB by performing the following equation: INL/DNL.

This accuracy can be expected to be greater than in rheostat mode. I'm currently looking for a way to convey this in comparison to the 0.1% you are looking for.

Any update? Would it help if we know the range of divider ratios?
