Hi everyone,
I am using a DRV8302 to drive a BLDC motor but DRV8302 Fault Pin always equal to zero. I share my drawing and measurement below;
I have run my circuit and Code Composer program. while EnableFlag=1, I have observed the following values.
1) PVDD=25V
2) GVDD=11V
3) AVDD=7V
4) DVDD=3V
5) EN_GATE=3V
6) M_PWM=3.2V
INL_A=3.2V PWM (I saw with an oscilloscope)
INL_B=3.2V PWM (I saw with an oscilloscope)
INL_C=3.2V PWM (I saw with an oscilloscope)
INH_A=3.2V PWM (I saw with an oscilloscope)
INH_B=3.2V PWM (I saw with an oscilloscope)
INH_C=3.2V PWM (I saw with an oscilloscope)
BST_A=11V
BST_B=11V
BST_C=11V
BST_BK=25V PWM (I saw with oscilloscope)
GL_A=0V
GL_B=0V
GL_C=0V
GH_A=1V
GH_B=1V
GH_C=1V
