micro corp. EGS002 Datasheets EG8010 demo board EGS002 Sinusoid Inverter Driver Board User Manual 1. Description EGS002 is a driver board specific for single phase 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 warning 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 integratescross-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-AC two stage power converter system or DC-AC single stage low power frequency transformer system for boosting. EG8010 can achieve 50/60Hz pure sine wave with high accuracy, low harmonic and distortion by external 12MHz crystal oscillator. EG8010 is a CMOS IC that integrates SPWM sinusoid generator, dead time control circuit, range divider，soft start circuit, circuit protection, RS232 serial communication, 12832 serial LCD unit, and etc. 2.

JP9 When JP9 is short, LCD backlight is on When JP9 is open, LCD backlight is off The driver board’s jumperJP5, JP2, JP7 and JP8 are shorted as default setting, corresponding to 50Hz output, soft start mode on, 300nS dead time. Users can change these based on their needs. Warning: Jumper of the same function CANNOT be short circuited at the same time. (For example: JP1 And JP5 cannot be short at the same time.)

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.Shielding cable is required for connecting 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 thatwe 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. *7. *6. *5. *4. *3. *2. *1.

When TEST3 and TEST4 are connected to RC filter, it will output waveform shown as CH2 red waveform in figure 5-3. 4) Because pin VFB is grounded, undervoltage protection is going to turn on in 3 seconds. Test1~Test 4 will all shut down; LED blinks four times, off for 2 seconds and keep cycling. When EGS002 is connected to the power supply again, user can observe waveforms for another 3 seconds.
