Flexible High-Power System PMIC - Dialog Semiconductor
Description
DA9053
Flexible High-Power System PMIC with 1.
8 A Switching USB Power Manager
General Description
The DA9053 is a quad buck 1 A per channel PMIC subsystem with supply domain flexibility to support a wide range of application processors, associated peripherals and user interface functions.
Combining a dual input switched-mode USB compatible charger, full power path management, four bucks, ten linear regulators and support for multiple sleep modes: the DA9053 offers an energyoptimized solution suitable for portable handheld, wireless, industrial and infotainment applications.
The high-efficiency Li-lon/Polymer switching charger supports precise current/voltage charging as well as pre-charge and USB modes without processor interaction.
During charging, the die temperature is thermally regulated enabling high-capacity batteries to be rapidly charged at currents up to 1.
8 A with minimum thermal impact.
USB suspend mode operation is supported and, for robustness, the power inputs are protec...
