Chip Description

EG8015 is a digital-analog integrated chip with a built-in two-channel 600V half-bridge high-voltage MOS driver and SPWM sine wave generator, specially designed for inverter products.

EG8015 has a built-in 24MHz high-speed clock oscillator with ±1% accuracy, or can be configured with an external high-precision 24MHz crystal oscillator via the UART port, enabling it to be a dedicated chip for high-precision, low-distortion, and low-harmonic pure sine wave 50Hz or 60Hz inverters.

The chip adopts CMOS technology and integrates functions such as SPWM sine wave generator, dead time control circuit, amplitude factor multiplier, soft start circuit, protection circuit, and UART serial communication interface.

The chip uses a QFN39 package. With only a few external components, it can achieve a no-load waveform distortion rate of less than 1.5% and a full-load waveform distortion rate of less than 3%, meeting the waveform requirements of the inverter industry.

It integrates one operational amplifier and one comparator. The operational amplifier is used for output voltage differential feedback processing, and the comparator is used for output short-circuit protection.

The chip has an SCP short-circuit protection input pin. The SCP pin has a cycle-by-cycle shutdown function, which, combined with an external comparator, can realize the inverter's output short-circuit protection function.

Built-in comprehensive protection functions, providing AC output undervoltage and overvoltage protection, overcurrent protection, overtemperature protection, and short-circuit protection indication.

Built-in UART serial communication function allows users to set configuration parameters or read the inverter's operating status and relevant data via the serial port.
