A PWM generator controls a first transistor and a second transistor of the DC-DC converter according to the first and second signals. The first transistor is coupled between the input voltage and the phase node, and the second transistor is coupled between the phase node and a ground....
The PWM at the motor winding can be as low as one diode drop below ground. This PWM is also experienced by the inline current sensing amplifier. Since the MIN common mode voltage spec for INA181 is -0.3V, the diode drop is very likely lower. Which may result ...

5.6.2 Sensing of ac mains and dc-link voltage signal The Hall-effect voltage sensors are used for sensing of ac mains voltage and the dc-link voltage of the converter. The output of the voltage sensors are inputted in any two ADC channels of the DSP. The ac mains voltage is used for...
output voltage sensing. Inputs DIFFP and DIFFN are tied to the point of load, and the difference between them is expressed with respect to local ground from the DIFFOUT pin. Measurement error is limited to the input offset voltage of the differential amplifier, which is no more tha...
