Integrated USB Type-C PD and 1-4 Cell Batteries Charging Reference Design.pdf
(2.23 MB)
This reference design includes a highlyintegrated USB PD sink controller HUSB238 and a highly integrated Buck-boostcharger MP2651. This reference design can support charging 1 to 4 cellbatteries through a USB Type-C port. The HUSB238 negotiates with a USB PD poweradapter (PD source). It can be set to request the any available Power DataObject (PDO), charging 1-4 cell batteries through the charger MP2651. Throughthe I2C interface, the PD negotiation can be set up. The bus voltage,the battery voltage, the battery charging current and component temperature canbe monitored in real time. This board features maximum input power of up to 20V3A,without the need for any external FETs enabling a much smaller design size,reducing total BOM cost. This reference design provides an ultra-miniature,high reliability integrated USB PD and 1-4 cell batteries charging solution
