Overview
HM5154 is an efficient synchronous buck conversion charging IC that integrates MOS and input fast charging protocols.
The input voltage range of HM5154 is 5V~12V; HM5154 integrates the input fast charging protocol of HM5154 Type-C PD, Huawei FCP, Samsung AFC, and MTK PE+1.1/2.0. You can apply for 9V or 12V voltage from the adapter to reduce the charging time; HM5154 can Set the charging current of the input end through the ISET pin. When the input is 9V/2A, the maximum charging current of the battery end is 3.7V/4.8A; it can be compatible with small current adapters. When the adapter output load capacity is insufficient, the charging current will be adaptively reduced to ensure no Pull the adapter;
