Product Description

Product Introduction

SK88F064 Series

The SK88F064 series is a charging management MCU specially designed for AC-DC chargers. It integrates dual 16-bit high-precision DAC charging loops, hardware overcurrent detection circuits, 10/20/40/60 times current amplification circuits, and universal control cores into one, which greatly simplifies the design of peripheral circuits, reduces system BOM costs and PCB area, and improves system reliability and response speed through hardware-level integration.
