We're evaluating using INA233 in our design.
Design Parameters:
a) Max. expected current = 98.3mA. So, Current_LSB = 3.00 E-06
b) VBUS voltage = 5V +/- 10%
c) High-Side Shunt Resistor = 100mOhm, 0.1%
d) So, CAL = 17066 => Hex = 42AA
Question:
1) Is Resnse resistor & CAL values are fine? Any suggestions on Rsense resistor value?
2) X = 1/ m * (Y * 10-R - b). Y = a 2-byte, two's complement integer received from the device. Do we need to convert two's complement integer that is received from the device while sustituting values in X = 1/ m * (Y * 10-R - b)? Can you elaborate on this?
