EG1612
Chip Features Specifically designed for push-pull or full-bridge circuits for pre-boosting inverters. Integrated three-channel high-voltage 260V half-bridge drivers with a drive capability of ±1A. Output voltage feedback uses an under-closed-loop control method. Adjustable operating frequency, ranging from 40KHz to 111KHz. PWM soft-start function with a soft-start time of 1S. 50% duty cycle output, dead time of 500nS. Real-time processing of voltage, current, and temperature feedback. Overvoltage, undervoltage, overcurrent, and overtemperature protection functions. Supports UART serial communication with a baud rate of 9600. Yijing Microelectronics Co., Ltd. can modify the functions or parameters according to customer applications. Operating power supply: +5V and +12V. Package type: QFN32

Chip Description
The EG1612 chip is a control chip specifically designed for push-pull or full-bridge boost in inverter front-ends. It integrates three high-voltage half-bridge drivers and provides battery undervoltage and overvoltage shutdown, undervoltage buzzer, and overcurrent shutdown protection. It outputs two push-pull mode 40K-111KHz PWM signals. The voltage feedback adopts a shallow closed-loop voltage regulation mode, which can achieve the highest voltage limit, preventing the voltage from being too high during no-load operation and causing MOS tubes to burn. At the same time, it saves the filter inductor of the transformer output, reducing the overall cost and PCB space.
