Preliminary
Power Management IC with Single Cell Li-Battery Switching Charger Integrated Power Path Controller
General Description
The RT5037 is a highly integrated smart power management IC which includes: switch-mode single cell Li-Ion/Li-Polymer battery charger, LDO, synchronize Buck regulator, Load Switch, and RTC-OSC for portable applications. The RT5037 also Features
USB On-The-Go (OTG) support.
The RT5037 optimizes the charging task by using a control algorithm to vary the charge rate via different modes, including pre-charge mode, fast charge mode, and constant voltage mode. The key charge parameters can be programmed via the I2C interface. The RT5037 resumes the charge cycle whenever the battery voltage falls below an internal threshold and automatically enters sleep mode when the input power supply is removed.
Four integrated Synchronize Buck Regulators are designed to provide MAX 2/2/1.6/1.6A application with high efficiency.
Four integrated LDOs are designed...
