DRV8305-Q1: Temperature dependence of G_csa

Yuto Kitamura

Expert 6605 points

Part Number: DRV8305-Q1

Tool/software:

Dear team,

Would I know temperature dependence of G_csa?

I could see the typical value of G_csa and G_err in 2 temperature range in datasheet. Can we get the graph that shows G_csa vs. temperature? is it positive correlation to temperature or negative? Is it polarity or exponentially or any other dependence?

Thank you and best regards,
Yuto Kitamura

Hey Kitamura-san,

Thank you for your patience.

We do not have the graph to share but I can speak generally about gain and gain error.

We expect an inverse relation between gain and temperature and a direct relation between gain error and temperature.

Best,

Akshay
