DRV8801, does it have internal oscillator for charge pump

Hi,

I am planning to use DRV8801 as a gate driver and to just change the rotation direction of a motor. so there is no PWM, My motor may run for minutes in one direction. Basically I am planning to apply DC to one pair of the 4 bridge mosfets. This may mean that the charge pump capacitor does not get recharged. I see Allegro A3950 has an internal oscillator (as seen on functional block diagram on page 3 of datasheet) for charge pump, implying that the lower mosfets do not need to switch on/off to keep the charge pump capacitor charged. Does DRV8801 have such an oscillator?

Thanks,

Persa
