Questions of DRV10983

Other Parts Discussed in Thread: DRV10983

the following questions are the new questions we get from our customer.

1. we want to know how to forecast and calculate the junction temperature in actual measurement? A data from results is like this. Room temperature is 23C, IC Package Top temperature is 68C and IC bottom temperature is 54.3C. inverter loss is 1~1.5W. could you let us know how to calculate junction temperature use these information ?

 

2.what’s min & max value of Over Temp Protection ? They want to know more information about shutdown temperature. The typical value of shutdown temperature is 150C in datasheet( DRV10983, Page 7 ). and they want to know the Min shutdown temperature and Max shutdown temperature?

 

3. Could we use I2C communication to change t_adv value in real-time ?

 

4. we like to get the functional block diagram of DRV10983 control algorithm in high level, would it be possible to provide it?
