UBA2016A/15/15A
600 V fluorescent lamp driver
7.3.1 VDD supply
The UBA2016A/15/15A is intended to be supplied by a start-up bleeder resistor
connected between the bus voltage V BUS and VDD and a dV/dt supply from the
half-bridge point at pin SHHB.
The IC starts up when the voltage at pin VDD rises above start-up voltage V startup(VDD) and
locks out (stops oscillating) when the voltage at pin VDD drops below stop voltage
V stop(VDD) . The hysteresis between the start and stop levels allows the IC to be supplied
by a buffer capacitor until the dV/dt supply is settled. The UBA2016A/15/15A has an
internal VDD clamp. This is an internal active Zener (or shunt regulator) that limits the
voltage on the VDD supply pin to clamp voltage V clamp(VDD) . No external Zener diode is
needed in the dV/dt supply circuit if the maximum current of the dV/dt supply minus the
current consumption of the IC (mainly determined by the gate drivers’ load) is below
I clamp(VDD) .
7.3.2 Low- and high-side drivers
The low- and high-side drivers are identical. The output of each driver is connected to the
equivalent gate of an external power MOSFET. The high-side driver is supplied by the
bootstrap capacitor, which is charged from the VDD supply voltage via an internal diode
when the low-side power MOSFET is on. The low-side driver is directly supplied by the
VDD supply voltage.
7.3.3 Non-overlap
During each transition between the two states GLHB HIGH/GHHB LOW and
GLHB LOW/GHHB HIGH, GLHB and GHHB will both be LOW for a fixed non-overlap time
t no to allow the half-bridge point to be charged or discharged by the load current
(assuming the load always has an inductive behavior), and enabling zero voltage
