Description EGS002 is a driver board specific for single pha se sinusoid inverter. It uses ASIC EG8010 as control chip and IR2110S as driver chip. The driver board integrates functions of voltage, current and temperature protection, LED warn ing indication and fan control. Jumper configures 50/60Hz AC output, soft start mode and dead time. EGS002 is an improved version of EGS001 that is compatible of EGS001’s original interfaces. EGS002 also integratescr oss-conduction prevention logic to enhance its ability of anti-interference, and LCD display interface for users’ convenience to use chip’s built-in display function. EG8010 is a digital pure sine wave inverter ASIC (Application Specific Integrated Circuit) with complete function of built-in dead time control. It applies to DC-DC-A C two stage power converter system or DC-AC single stage low power fr equency transformer system for boosting. E G8010 can achieve 50/60Hz pure sine wave with high accuracy, low harm onic and distortion by external 12MHz crystal oscillator. EG8010 is a CMOS IC th at integrates SPWM sinus oid generator, dead time control circuit, range divider，soft start circuit, circuit protection, RS232 serial communication, 12832 serial LCD unit, and etc. 2.

3.4 LED Warning Indication

EGS002 driver board provides LED warning indi cation function. User can determine problem according to the followings:  Normal：Lighting always on  Overcurrent：Blink twice, off for 2 seconds, and keep cycling  Overvoltage：Blink 3 times, off for 2 seconds, and keep cycling  Undervoltage：Blink 4 times, off for 2 seconds, and keep cycling  Overtemperature：Blink 5 times, off for 2 seconds, and keep cycling

3.5 LCD Display Interface

EGS002 integrates LCD display interface for users’ convenience to test chip’s built-in display function that EG8010 supports.Shieldi ng cable is required for conne cting EGS002 driver board and LCD, otherwise inverter’s high voltage and high current environment will significantly interfere driver board’s operation. EG8010 supports 12832 LCD (default) orLCD3220 th atwe specifically designed. Because two LCDs’ drivers are different, user has to specify if intends to buy LCD3220. Salesperson will ship 12832 LCD as default if not otherwise specified.  12832 LCD Connection Diagram： Figure 3‐2. Connection betweenEGS002 and 12832 LCD Figure 3‐3. 12832 LCD Display Note： There are many modules of LCD in the mark et. EG8010 supports majority of 12832 LCD based on control IC ST7920.
