Part Number: BOOSTXL-DRV8323RH
Hi,
I'm trying to interface with BOOSTXL-DRV8323RH and DSP28377S.
I used 6xPWM mode.
below is conneting list. PWMxA, PWMxB is signal from DSP28377S.
--------------------------------------
mode - GND ( to make 6xPWM mode)
enable - VCC
INHA - PWM1A
INLA - PWM1B
INHB - PWM2A
INLB - PWM2B
INHC - PWM3A
INLC - PWM3B
--------------------------------------
when I apply pwm signal as below, then most signal GHx is correct except GHC.
GHC should be low, but GHC is high and GHL is low.
What should I do? Is there any connection need?
I also check nFAULT, but it is high, so it might be work well.
PWM1A - pwm, PWM1B - !pwm
PWM2A - low, PWM2B - high
PWM3A - low. PWM3B - low
