Product specification
600 V CCFL ballast driver IC
UBA2070
Power-down state
The Power-down state will be entered if, at the end of the
ignition time, the voltage at pin LVS is above V
LVS(fail)
.
In thePower-downstatetheoscillationwillbestoppedand
MOSFETs T
hs
and T
ls
will be non-conductive. The V
DD
supply is internally clamped. The circuit is released from
the Power-down state by reducing the supply voltage to
below V
DD(reset)
.
Capacitive mode protection
The signal across R
ACM
also gives information about the
switching behaviour of the half bridge. If the voltage at
R
ACM
does not exceed the V
CMD
level during the
non-overlap time (see Fig.4), the Capacitive Mode
Detection (CMD) circuit assumes that the circuit is in
capacitivemodeofoperation.Consequentlythefrequency
will be directly increased to f
max
. In this event the
frequency behaviour is decoupled from the voltage at
pin CSWuntilthevoltageisdischargedtozero.Aninternal
filter of 30 ns is included at pin ACM to increase the noise
immunity.
Charge coupling
Due to parasitic capacitive coupling to the high voltage
circuitry all pins are charged with a repetitive charge
injection. Given the typical application the pins
I
REF
and CF are sensitive to this charge injection. For
charge coupling of
±
8 pC, a safe functional operation of
the IC is guaranteed, independent of the current level.
Charge coupling at current levels below 50
μ
A will not
interfere with the accuracy of the V
CS
and V
ACM
levels.
Charge coupling at current levels below 20
μ
A will not
interfere with the accuracy of any parameter.
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 60134); all voltages referenced to ground.
Note
1.
In accordance with the human body model: equivalent to discharging a 100 pF capacitor through a 1.5 k
series
resistor.
