Using PWM duty control to simulate the idea sine wave output current. Sine Wave Modulation (internal signal) Sinusoidal PWM Output (UO,VO,WO) Figure 6: Sine Wave Modulation PWM Output Lockup Protection and Automatic Restart The APX7320 provides the lockup protection and automatic restart functions for preventing the coil burnout while the fan motor is locked. When the lock-restart cycle repeated to 20 times, the output will be shut down until pull low VSP pin or re-power on. Connecting the capacitor from CT pin to SGND can determine the shut down time and restart time. Current Limit and Over Current Protection (OCP) The APX7320 includes an internal current sense circuits for current limit and over-current protection (OCP). When the total current of three phase over the current limit level, the high side driver will be turned off to stop supplying current to the motor. If the total output current over the OCP current level, the OCP function will be enable to turn-off all of the high side output driver to prevent output short through condition until pull low VSP pin or re-power on. Thermal Protection The APX7320 is designed with a thermal protection to protect the IC from the damage of over temperature. When internal junction temperature reaches 165oC, the output devices will be switched off. When the IC’s junction temperature cools by 30 oC, the thermal sensor will turn the output devices on again resulting in a pulsed output during continuous thermal overload. Copyright ANPEC Electronics Corp. Rev. P.1- Aug., 2015 15 www.anpec.com.tw Preliminary APX7320 Application Information Input Capacitor For the noise reduction purpose, all of the capacitors in application circuit should be placed as close as possible to the IC pin. 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 × ( VCTH − 0.2V ) ICT1 CCT × ( VCTH − VCTL ) ICT1 Shutdown Time = CCT × ( VCTH − VCTL ) ICT 2 For example: VCC=24V, CCT=1µF VCTL=1V, VCTH=3V, ICT1=2µA, ICT2=0.4µA Locked Detection Time = 1.4s Restart Time = 1s Shutdown Time= 5s The value of CCT must be considered with soft start up result. START Capacitor The START pin capacitor is used to set the force start up timing (TSTART) of one step (60oC) for sine-wave start up. Adjust START capacitor can set the start up timing for different motor or loading of fan motor. TSTART = 2 × (VSTARTH − VSTARTL ) × CSTART × 32 × 32 ISTART For example: CSTART =2.2nF VSTARTL=0.8V, VSTARTH=1.6V, ISTART=7µA The force start up time is 515ms Copyright ANPEC Electronics Corp. Rev. P.1- Aug., 2015 16 www.anpec.com.tw APX7320 Preliminary Application Information S-S Capacitor The S-S capacitor is used to set the output duty change rate for soft start. The time (TS-S) is define the time of output duty from 0% to 100%. TS − S = 2 × (VS − SH − VS − SL ) × CS − S × 32 × 256 IS − S For example: CS-S =2.2nF VS-SL=0.8V, VS-SH=1.6V, IS-S=7µA The time (TS-S) of duty change from 0% to 100% is 4.12s The choices of CT pin and S-S pin capacitors should be considered that fan must start up during restart time at lock mode. When the CCT is determined and the fan can’t start up at power-on or lock-restart mode, decrease the CS-S capacitance can let the fan start up successfully but it will reduce the soft start time. FIL Capacitor The capacitor connects between HUP and HUM (HVP and HVM, HWP and HWM) pin to filter the noise when phase change to make sure phase change correctly. Its capacitance from 1nF to 10nF is recommended. Copyright ANPEC Electronics Corp. Rev.
