New: Richtek RT9471H/HD RT9472/D – 3A Single Cell Switching Battery Charger

The RT9471H/HD and RT9472/D are 3A, 3.9V~13.5Vin single cell switching battery charger ICs with system power path management and USB-OTG. During charging mode, it has pre-charge mode, 0~3.15A CC mode, and 3.9V~4.7V CV mode. It implements JEITA protection to adjust charging parameters for input current limit via data lines or voltage level indication. Under OTG mode, it has 4.85V~5.3V output voltage limit regulation in 150mV steps, and 6.5V OVP. It has 6A maximum discharge current and the charging path can be entirely cut off for power saving. The I²C interface makes it a truly flexible solution.
