Ballast Control IC
Features
Description
„ Floating Channel Designed for Bootstrap Operation to
The FAN7532 provides simple and high-performance
electronic ballast control functions. Optimized for an
electronic ballast, the FAN7532 requires a minimum
board area and reduces component counts. The
FAN7532 is intended to drive two power MOSFETs in the
classical half-bridge topology with all the features
needed to properly drive and control a fluorescent lamp.
The FAN7532 has many comprehensive protection
features that work through filament failure, failure of a
lamp to strike, and automatic restarts. A dedicated timing
section in the FAN7532 allows the user to set the
necessary parameters to preheat, ignite, and run the
lamp properly.

1. Start-up Circuit
The gate drive output frequency is half that of the triangular waveform on timing capacitor (CT) at pin #6. In
normal operating mode, the timing capacitor charging
current is 4•Irt (=Vref/RT). The discharging current is 6.2
times the charging current. During the charging period of
the timing capacitor (CT), the MOSFET alternatively
turns on. During the discharging period of the timing
capacitor (CT), both MOSFETs are off.
The start-up current is supplied to the IC through the
start-up resistor (Rst). To reduce the power dissipation in
Rst, Rst is connected to the full-wave, rectified output
voltage. The size of Rst can be determined by equations
(1) and (2).

The size of supply capacitor (Cs) is normally determined
by the start-up time and the operating current which is
built up by the auxiliary operating current source. The
turn-off snubber capacitor (CQ) and two diodes (D1, D2)
constitute the auxiliary operating current source for the
IC. The charging current through the CQ flows into the IC
and charges the supply capacitor. If the size of CQ is
increased, the VCC voltage on the Cs is also increased.

FAN7532 Ballast Control IC
Application Information
The ignition mode is defined as the IC’s internal status
when VCPH is approximately between 2.9V and 5V.
During ignition, the operating frequency is decreased to
a pre-determined value. At the same time, a very highvoltage for igniting the lamp is established across the
lamp. When the VCPH exceeds 2.9V, the FAN7532
enters the ignition mode. Once VCPH exceeds 5V, the
device enters the run mode described in the following
section. In the ignition period, the internal 10mA current
source charges the external preheating timing capacitor
(CPH) to increase noise immunity with the sharp slope of
the VCPH. The ignition time is determined by the CPH

4. Preheating Mode
The preheating mode is defined as the IC’s internal
status when the VCPH is between 0V and 2.9V. During
preheating, the current that flows through the ballast
circuit heats the lamp filaments. This is necessary for
maximizing lamp life and reducing the required ignition
voltage. When the VCC exceeds the UVLO high
threshold, the preheating time set-up capacitor, CPH,
starts being charged by the internal 1.5µA current source
until the VCPH reaches 2.9V. Until the VCPH reaches
2.9V, the switching frequency throughout the preheating
mode is determined by CT and RPH.
CPH
and internal 10mA current source ( ΔTign = CPH × ΔIVCPH
). In this
mode, the switching frequency is determined by CT,
RPH, and RT. Therefore, the charging and discharging
currents change according to VCPH and are determined
by equation (7).

After the lamp has successfully ignited, the FAN7532
enters run mode. The run mode is defined as the IC’s
internal status when VCPH is higher than 5V. In this
mode, the lamp is being driven with a normal power level
after the lamp is discharged. The run mode switching
frequency is determined by the timing resistor RT and
the timing capacitor CT. When the VCPH exceeds 5V, the
protection-masking mode is disabled and the IC can
enter the protection mode. The running frequency is
determined by the amount of charging and discharging
current to CT capacitor.
The preheating frequency is determined by the amount
of charging and discharging current to the CT capacitor.
The charging and discharging current during preheating
mode is decided by equation (4):
I pre _ ch = 4 ×
( 5V − VCPH )
6. Run Mode
The preheating time is determined by the CPH and the
1.5µA current source. Therefore, the preheating time is
determined by equation (3):

0V ≤ VCPH ≤ 2.9V , ;Preheating Frequency
The FAN7532 has two types of protection modes.
is broken, deactivated, or the lamp is deeply blackened
around the cathodes. In this state, the ballast constantly
generates very high voltage between two cathodes to
ignite according to a specific procedure in the control IC.
When the voltage of OVP pin exceeds 2V, the IC
instantly enters the protection mode. To exit this mode,
the VCC must be recycled below the UVLO low
threshold.
1) Over-Voltage Protection (OVP) Mode
The OVP pin is normally connected to the external
components that detect lamp voltage between a lamp’s
cathodes. This voltage is always maintained under 2V in
normal operation. If the lamp enters the end-lamp-life or
abnormal condition, the lamp does not turn-on even if
there is enough voltage supplied between two cathodes.
Normally, this condition means that one of the cathodes

enters the protection mode. However, the FAN7532 outputs are only disabled in this mode. To exit protection
mode, the lamp must be replaced or correctly connected
to the ballast.
After the lamp has successfully ignited, the FAN7532
enters run mode. In this mode, if one of the cathodes
isn’t correctly connected to the ballast, the ballast stops
operation for safety until the lamp is changed and a new
one is connected between the lamp and the ballast. As
soon as the voltage of OLP pin exceeds 2V, the IC

8. PCB Layout Guides
circuit to reduce common-mode noise due to output
switching.
Component selection and placement on the PCB is very
important when using power control ICs. Bypass the VCC
to GND as close to the IC terminals as possible with a
low ESR/ESL capacitor, as shown in Figure 20. This
bypassed capacitor can reduce the noise from the power
supply parts, such as a startup resistor and a charge
pump. The GND lead should be directly connected to the
low-side power MOSFET using an individual PCB trace.
In addition, the ground return path of the timing components (CPH, CT, RPH, RT) and VCC decoupling capacitor should be connected directly to the IC GND lead and
not via separate traces or jumpers to other ground traces
on the board. These connection techniques prevent
high-current ground loops from interfering with sensitive
timing component operations and allow the entire control
