DESCRIPTION
HM1495 is a synchronous buck converter chip that supports multiple fast charging protocols and dual A-port output. It integrates 3.5A high-efficiency simultaneous Step-down converter, CC/CV mode, QC3.0/PE fast charging protocol and corresponding management logic. Only a small number of peripheral devices are needed Compose a complete high-performance QC3.0/PE fast charging dual-port car charger solution.
HM1495 supports dual-port output and supports two working modes: normal A-port priority mode and QC A-port priority mode. Set these two modes. The default is normal A-port priority mode, which can be expanded to QC A-port priority mode.
