Linear current sensing circuit for motor controller |
摘要 |
The circuit converts an analog current sense signal, in a motor drive controller circuit, from a high side reference potential to a low side reference potential for measurement and processing. The circuit comprises a section for converting the input signal, at a first potential, into a pulse width modulated (PWM) signal. A further circuit section is provided for level shifting the pulse width modulated signal from the first potential to a second potential.
