LTC3576/LTC3576-1 Switching Power Manager with USB On-the-Go + Triple Step-Down DC/DCs DESCRIPTION
The LTC®3576/LTC3576-1 are highly integrated power management and battery charger ICs for Li-Ion/Polymer battery applications.

They each include a high efficiency, bidirectional switching PowerPathTM manager with automatic load prioritization, a battery charger, an ideal diode, a controller for an external high voltage switching regulator and three general purpose step-down switching regulators with I2C adjustable output voltages. The internal switching regulators automatically limit input current for USB compatibility and can also generate 5V at 500mA for USB on-the-go applications when powered from the battery. Both the USB and external switching regulator power paths feature Bat-Track optimized charging to provide maximum power to the application from supplies as high as 38V. An overvoltage circuit protects the LTC3576/LTC3576-1 from damage due to high voltage on the VBUS o
