8.3.11.2 Using PWM for Digitally Controlled Enable

If using the PWM pin as to provide and enable function, ensure the signal edge rate is adequate (< 100 ns) when measured at the device PWM pin to prevent the device from turning ON and turning OFF when the level transitions through the 1-V threshold region. If the edge is too slow or if the high level is not adequately above the 1-V threshold, a small capacitor may be required on the PWM pin to avoid multiple turn-ON and turn-OFF cycles when passing through this region.
