HM1496中文资料华之美半导体数据手册PDF规格书

Overview

HM1496 is a synchronous buck converter chip that supports multiple fast charging protocols and Type C output. It integrates 3.5A high-efficiency simultaneous Step-down converter, CC/CV mode, QC3.0/PE fast charge protocol, Type C protocol and corresponding management logic. Peripheral only needs a small amount A complete high-performance QC3.0/PE fast charging Type C car charger solution can be formed.

HM1496 supports single and dual port output, supports two working modes: dual port mode and single port mode, these two modes can be set through Pin Mode.
