Li+ Battery Charger With WLED Driver and Current Shunt Monitor         Â
  The TPS65200 integrates a high-efficiency, USB-friendly switch-mode charger with OTG support for single-cell Li-ion and Li-polymer batteries, D+D- detection, a 50-mA fixed-voltage LDO, a high-efficiency WLED boost converter, and high-accuracy current-shunt monitor into a single chip. The charger features a synchronous 3-MHz PWM controller with integrated power MOSFETs, input current sensing and regulation, input-voltage dynamic power management, high-accuracy charge current and voltage regulation, and charge termination. It charges the battery in three phases: low-current pre-charge, constant current fast-charge, and constant voltage trickle-charge. The input current is automatically limited to the value set by the host. The charger can be configured to terminate charge based on user-selectable minimum current level and to automatically restart the charge cycle if the battery voltage falls below the recharge threshold. A safety timer with reset control provides a safety backup for I2C interface. The charger automatically enters sleep mode or high impedance mode when the input supply is removed. The charge status is reported to the host using the I2C interface and STAT pin. The D+D- detection circuit allows automatic detection of a USB wall-charger. If a wall-charger is detected the input current limit is automatically increased from 500 mA to 975 mA.
