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 effi ciency,
bidirectional switching PowerPath™ 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 or WALL pins with
just two external components. The LTC3576/LTC3576-1 are
available in a low profi le 38-pin (4mm × 6mm × 0.75mm)
QFN package.
