Circuit for sensing motor load current |
摘要 |
<p>A current sensing circuit including a shunt resistor coupled, at one end, to the low-side transistor of a half bridge circuit and, at its other end, to a load. The voltage sensed across the shunt resistor is proportional to the current delivered to the load. A level shifting circuit is provided to transpose the sensed voltage to a low voltage signal which can be fed back to control commutation of the transistors in the half bridge circuit.</p> |
