DIR and PWM inputs
The pins DIR and PWM are internally pulled down. The bridge is controlled by these two
inputs according to the table below.
Table 6.
Figure 5.
The outputs can be disabled (set to tri-state) by the Disable and Enable inputs DI and EN.
Input DI has an internal pull-up. Input EN has an internal pull-down. During freewheeling
phase, an active freewheeling on the Low-Side MOS is automatically set, switching ON the
power transistor in parallel to the internal freewheeling diode.
