A.3 - Jun., 2008 9 www.anpec.com.tw APX9270 Function Description Variable Speed Control The APX9270 is designed with a variable speed controller which has two external input signals, a temperature signal sensed by a thermistor and an external PWM signal. Temperature Speed Control Using thermistor get temperature to make SET pin voltage. The fan’ speed is decided by comparing OSC and s SET pin voltage. In addition, the lowest drive duty is set by comparing the OSC oscillating voltage and MIN pin voltage (only for temperature speed control side). Temperature control system works by comparing the voltage of SET and OSC. When SET voltage is lower than OSC voltage, one OUT pulled high and another OUT pulled low. On the contrary, when SET voltage is higher than OSC voltage, upper side transistors are OFF; meanwhile, the coil current re-circulates lower side transistor. Therefore, with decreasing SET voltage, the output ON-Duty will be increasing, which results in the increasing of the coil current and motor rotation speed. External PWM Speed Control This is a pin for the direct PWM speed control. PWM pin input is pulled down to GND when it is not used. The minimum duty is performed by R6 and R7 resistances (see Typical Application Circuit). R7 is left open if you want to stop rotation when PWM duty is 0%. (see Figure 1: Rotation Control Curve) OUT -DUTY(%) External PWM-Duty Duty 100% VCT VOUT1 TON the fan is locked. Connecting the capacitor from CT pin to GND determines the shutdown time and restart time. As the fan is locked, the charge/discharge circuit will charge the CT capacitor to 3.6V by a 2.2µA source current for a locked detection time, and then the circuit will switch the capacitor to discharge. During the discharging interval, the output drivers are switched off until the CT voltage is discharged to 1.6V by a 0.22 µA sink current, and the circuit will switch the capacitor to charge. In the charging interval, the IC enters the restart time; one output is high and another is low, which makes a torque for fan rotation until the CT voltage is charged to 3.6V by a 2.2µA source current. If the locked condition still remains, the charge/ discharge process will be recurred until the locked condition is released (see Figure 2: Lock/Auto Restart Waveform). VINVIN+ VOUT2 TOFF TOFF VFG Lock Lock Detection Release Figure 2: Lock/Auto Restart Waveform Current Limit The APX9270 includes both internal and external current limiters. External current limiter value is programmed by RL which is located between VCC pin and VM pin. The external current limiter works when the voltage difference Duty 50 % Duty 0% between both sides of RL raises to be 0.48V or higher. For example, the RL=0.5 Ω , the external current limiter value is fixed and internally set at 960mA. The internal current limiter value is different in rotation mode and lock mode. It is 1.2A in rotation mode, but it decreases to 0.6A in lock mode. This feature can reduce power consumption while the fan is locked. In general application, it is TA (oC) Figure 1: Rotation Control Curve Lockup Protection and Automatic Restart The APX9270 provides the lockup protection and automatic restart functions to prevent the coil burnout while C opyright © A NPEC Electronics Corp.

Current Limit (Cont.) recommended to short RL resistance and remove CM capacitor to disable external current limiter because the internal current limiter is sufficient to avoid overload. FG Output The FG pin is an open drain output connecting a pull up resistor to a high level voltage for the speed detection function. When VIN- is larger than VIN+, the VFG is low (switch on); when VIN- is smaller than VIN+, the VFG is high (switch off). Leave it open when not in using. Thermal Protection The APX9270 is designed with a thermal protection to protect the IC from the damage of over temperature. When internal junction temperature reaches 160°C, the output devices will be switched off. When the IC’ juncs tion temperature cools by 20°C, the thermal sensor will turn the output devices on again resulting in a pulsed output during continuous thermal overload.

Also, SET or PWM=[H], “H” means that SET or PWM voltage is greater than OSC voltage. Application Information Input Protection Diode & Capacitor The input protection diode (D1) between supply voltage and VCC pin has to be used to prevent the reverse current flowing into the supply power. However, the protection diode will cause a voltage drop on the supply voltage. The current rating of the diode must be larger than the maximum output current. For the noise reduction purpose, a capacitor (C1/CM) must be connected between VCC/VM and SGND/PGND. The C1/CM should be placed near the device VCC/VM pin as close as possible. Setting of the Oscillator Frequency and Output Voltage The oscillator is used for PWM speed control. Compare the OSC and SET pin voltages can decide PWM duty and PWM frequency depends on the oscillator frequency. The oscillator is based on internal charge/discharge circuit. The circuit charges COSC to VOSCH by a 10µA source current, and then it will discharge C OSC t o V OSCL b y 10 µA sink current. The circuit can generate a triangular waveform. The triangular waveform is determinded by COSC, R2, R3, R4, and R4. (see Typical Application Circuit) VOSCH = V 6 VREG × VOSCL = V 6 VREG × R3 R2 + R3 R5 R 4 + R5 fOSC = 0.5 × ISOC1 ( VOSCH − VOSCL) × COSC For example: COSC=100pF, R2 = R5 = 10kΩ , R3 = R4 = 20kΩ, IOSC1=10µA VOSCH= 4V, VOSCL= 2V, fOSC=25kHz The recommended OSC frequency range is from 22kHz to 32kHz.

HB Bias Output and Hall Input Signals The IC outputs a 1.3V voltage on HB pin to provide bias for the external hall element. The IC also has two pins IN+ and IN- to receive the hall signals from the hall element. The hall signals are very weak so the layout tracks must be short and far away from those noise sources to avoid noise coupling. The hall input amplifier has 20mV hysteresis. Therefore, the recommended differential hall input voltage should be more than 60mV. CT Capacitor The capacitor that is connected from CT pin to GND determines the shutdown time and restart time. Locked Detection Time = Restart Time = CCT × (V CT1 − 0.2 V ) ICT1 Thermal Pad Consideration The thermal pad on the bottom of the TSSOP-20P package should be soldered down to a copper pad on the circuit board. Heat can be conducted away from the thermal pad through the copper plane to ambient. If the copper plane is not on the top surface of the circuit board, 8 to 10 vias of 13 mil or smaller in diameter should be used to thermally couple the thermal pad to the bottom plane. For good thermal conduction, the vias must be plated through and solder filled. The copper plane is used to conduct heat away from the thermal pad should be as large as practical. If the ambient temperature is higher than 25οC, a larger copper plane or forced-air cooling will be required to keep the APX9270 junction temperature below the thermal protection temperature (160οC). Thermal Consideration Refer to “Maximum Power Dissipation vs. Ambient Temperature”, the IC is safe to operate below the curve and it will cause the thermal protection if the operating area is above the line. For example, TA= 50οC, the SSOP20 package maximum power dissipation is about 0.95W. Power dissipation can be calculated by the following equation: CCT × (V CT1 − V CT2 ) ICT1 CCT × (V CT1 − V CT2 ) ICT2 Shutdown Time = where CCT = CT pin capacitor For example: VCC=12V, CCT=1µF Locked Detection Time = 1.545 s Restart Time = 0.909 s Shutdown Time = 9.091 s The value of charge capacitor in the range of 0.47µF to 1µF is recommended. FG Resistor The value of the FG resistor could be decided by the following equation PD = VCC − VOUT1 − VOUT2 × IOUT + VCC × ICC For example: When VCC = 12V, ICC = 6mA, IOUT = 300mA, VOUT1 = 11.66V, VOUT2 = 0.13V, then PD = 0.213W According the power dissipation issue, we could adapt this SSOP-20 package. ( ) RFG = V 6VREG − VFG IFG For example: V6VREG = 6V, IFG = 5mA, VFG = 0.2V, RFG = 1.16kΩ The value of resistor in the range of 1k Ω t o 10k Ω i s recommended. C opyright © A NPEC Electronics Corp.
