Part Number: BOOSTXL-DRV8301

Hi Team,

Having issues getting MOSFETs to PWM on BOOSTXL-DRV8301 while connected to J5, J6, J7, J8 of LAUNCHXL-F28377S. Using Matlab Simulink to program in LAUNCHXL-F28377S. MOSFETs does not switch for channels PWM2A/B, PWM6A/B, and PWM10A/B per Quick Start guide.


Can get BOOSTXL-DRV8301 to PWM on channels PWM7A/B, PWM8A/B, and PWM9A/B while connected to J1, J2, J3, J4.  PWM. Copied Simulink blocks switching PWM7A/B, PWM8A/B, and PWM9A/B; and changed the module from PWM7A/B, PWM8A/B, and PWM9A/B to PWM2A/B, PWM6A/B, and PWM10A/B.  This should have gotten PWM2A/B, PWM6A/B, and PWM10A/B on BOOSTXL-DRV8301 to switch but no PWM switching was detected. 


Additionally, PWM7A/B, PWM8A/B, and PWM9A/B is programmed to for Fs= 10kHz and D=.5.  PWM8A/B, and PWM9A/B operate as programmed.  PWM7A/B results are incorrect with Fs = 5Hz and there is strange waveform when MOSFET turns on which goes away.  Please see attached jpg. Both are pics show same acquisition of PWM7A, PWM8A, and PWM9A with a different time scale


Is there some configuration missed out?

Thank you.
