hello all
Greeting for the day, i am working on TLE82453 chip set device for controlling the load and the micro controller i am using to communicate Infineon TC277.
I am trying to set the setpoint register value and the PWM period value. i would like to request set point formula to derive the target current and also PWM period calculations related to setpoint target current.

Currently I am calculating using the below method.

To set target current 250mA, 250mA = x * lsb ----> lsb = (1500/2047)mA
x = 341 approx.
when i set the x as a set point value, I am reading the current as 700mA but not 250mA.

Kindly shed your thoughts on it.

Kind Regards,
Deepak
