7. Functional description
7.1 Supply voltage
The UBA2035 is powered by a supply voltage applied to pin HV, e.g., the supply voltage of
the full bridge. The IC generates its own low supply voltage for its internal circuitry.
Therefore an additional low voltage supply is not required. A capacitor has to be
connected to pin VDD to obtain a ripple-free internal supply voltage. The circuit can also
be powered by a low voltage supply directly applied to pin VDD. In this case pin HV should
be connected to pin VDD or pin SGND. The maximum current that the internal series
7.2 Start-up
With an increasing supply voltage the IC enters the start-up state i.e. the upper power
transistors are set in off-state and the lower power transistors are switched on. During the
start-up state the bootstrap capacitors are charged. The start-up state is de?ned until
V VDD = V startup(VDD) or V HV = V startup(HV) . The state of the outputs during the start-up phase
is overruled by the bridge disable function.
7.3 Oscillation state
As soon as the supply voltage on pin VDD exceeds V startup(VDD) or the supply voltage on
pin HV exceeds V startup(HV) , the output voltage of the full bridge depends on the control
As soon as the supply voltage on pin VDD becomes lower than V UVLO(VDD) or the supply
voltage on pin HV becomes lower than V UVLO(HV) , the IC enters the start-up state again.
