SD59D24B
USB POWER DELIVERY (PD) CONTROLLER FOR MOBILE POWER SUPPLY

    The SD59D24B is a highly integrated protocol and power control IC for mobile power supply. It integrates 4-channel USB ports (up to AACC) and is compatible with fast charging protocols such as PD3.0, PPS, QC4.0 +, FCP, SCP, SFCP, AFC, BC1.2, APPLE, VOOC. Two boost/buck control circuits are integrated to realize CCCV control of two independent power supplies. Built-in high-precision ADC realizes charge and discharge management of lithium battery.

SD59D24B integrates abundant functions, providing complete solution for fast charging mobile power supply. The periphery of the system is simple, which greatly reduces BOM cost.
