I'm looking for a solution to control the direction of a powerful DC Motor. I came up with the idea to use a H-Bridge. Since the motor uses up to 3.2A the amount of possible H-Bridges is quite limited. The supply voltage on my quad is 3.7V. Since my outputs are limited I want to control the position using only one Digital Output. Which does work in one direction if set to 0 and other direction if set to 1. The PWM output should control the velocity.
Is that even possible?
I found this one but I have absoultely no clue if this one can be controlled only with 2 inputs per motor (1 PWM , 1Digital Output).

Above is a section from the data sheet. As you can see, the bridge needs all four data lines (IN1L, IN1H, IN2L & IN2H) connected to control it properly.
