Other Parts Discussed in Thread: DRV8332,
Hi Motor Drive Team,
To measures the dc-link current instead of phase currents, the GND_A,B,C pins and GND pins are connected all together (at junction A), and a current sensing resistor (Rsense = 0.01 ohm) is placed between the junction A and the ground of PVDD.
Question is whether GND_x and GND pins can accept 0.1~0.3 voltage to test and calibrate the differential amplification ckt of the current messurement ckt.
Actually the test voltage(0.1V) will be applied to the ternminal of the Rsense. If it is possible, every single board and circuit will be tested.
Thanks
