Description
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.

FAN7532 Ballast Control IC
Application Information
1. Start-up Circuit
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).
DC 400V
3. Oscillator
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 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.

2. Under-Voltage Lockout (UVLO)
The UVLO mode of the FAN7532 is designed to maintain an ultra low supply current of less than 120A, and to guarantee that the IC is fully functional before two output drivers are activated.

5. Ignition Mode
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 and internal 10mA current source ( Tign = CPH x IVCPH ). In this CPH 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).
ICT = IRT +
ICT = IRT +
IPH - IRT ( 5V - 2.9V ) = IPH ( 5V - 2.9V ) ;Ignition Frequency IPH - IRT

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 1.5A 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. The preheating time is determined by the CPH and the 1.5A current source. Therefore, the preheating time is determined by equation (3):
t pre = CPH x VCPH Icharging
( 5V - 2.9V )
IPH - IRT
( 5V - VCPH )
(7)
6. Run Mode
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 charging and discharging currents during preheating mode are decided by the equation (8):
Irun _ ch = 2 x Vref RT
(3)
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 x I pre _ disch = 4 x Vref RPH

7. Protection Modes
The FAN7532 has two types of protection modes. 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 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.

2) Open Lamp Protection (OLP) Mode
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
15.6V VUVLO+ VUVLO-
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.

8. PCB Layout Guides
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
circuit to reduce common-mode noise due to output switching.
