How to control these MOSFETS and BJTs --- Active High or Active Low?

[snoop911]

If I'm reading the circuit on the left correctly, to place Vin on PhaseA, you would drive the AH control line HIGH. Similarly, to short Phase A to ground, the AL signal going to the N-Mosfet must also be Active HIGH. And AH and AL must never be driven High at the same time, or else this would shourt VIN to GROUND, Is this correct?

The circuit on the right however, has N-BJT AND MOSFETS connected together, so not sure how to read this.. would HW and LW be active HIGH or LOW in order to connect Phase W to either Vin / GROUND?

No, your circuit will give a low voltage to the motor.
The gate of the upper Mosfet must be 10V higher than Vmotor since the Mosfet is a source-follower. The IR2101 circuit provides this boosted voltage.
