Introduction

AI Translation

The EG4328 integrates a high-precision 2.5V voltage reference, configurable multi-channel error amplifiers, an 8-channel 10-bit ADC, an I²C bus controller, a digital control module, and LED constant-current drivers. It is a programmable analog-digital mixed-signal power management IC featuring low power consumption and high flexibility. Paired with a low-cost 8-pin MCU (no ADC capability required), it enables advanced power management systems, making it ideal for intelligent battery management applications.

Features

AI Translation
