7.4 3-state function
If the input from the PWM controller becomes high impedance (3-state) for longer
than t_d(3-state), then both MOSFETs are turned off and the VI input is driven to 2.5 V
by an internal 2 x 10 kΩ resistor voltage divider between an internal 5 V reference
and ground. Once the V_I input is outside the 3-state window for longer than t_d(3-state)
normal operation will commence.
