I would like to design a high-precision hysteresis analog current controller board that provides 5V logic output to the IGBT gate driver. The board will be able to set reference from 0V to 5V which corresponds to 0A to 300A. I want to set the reference externally therefore TPS5210 is not suitable due to the limited voltage range of 1.3 V to 3.5 V. Since high precise control is critical, the hysteresis band should also be around 300uV (18mA). I would appreciate hearing some ic or design suggestions.
