SLVS606C – SEPTEMBER 2005 – REVISED FEBRUARY 2007
SINGLE-CELL Li-ION BATTERY- AND POWER-MANAGEMENT IC
FEATURES
•
BATTERY CHARGER
– Complete charge management solution for
single Li-Ion/Li-Pol cell with thermal
foldback, dynamic power management,
and pack temperature sensing, supporting
up to 1.5-A maximum charge current
– Programmable charge parameters for AC
adapter and USB port operation
INTEGRATED POWER SUPPLIES
– A total of 9 LDOs are integrated:
– Six adjustable output LDOs (1.25-V to
3.3-V)
– Two fixed-voltage LDOs (3.3-V)
– One RTC backup supply with low
leakage (3.1-V)
– Two 600-mA, programmable dc/dc buck
converters (0.6-V to 3.4-V) with enable,
standby-mode operation, and automatic
low-power mode setting
DISPLAY FUNCTIONS
– Two open-drain PWM outputs with
programmable frequency and duty cycle.
Can be used to control keyboard backlight,
vibrator, or other external peripheral
functions
– RGB LED driver with programmable
flashing period and individual R/G/B
brightness control
– Constant-current white LED driver, with
programmable current level, brightness
control, and overvoltage protection can
drive up to 6 LEDs in series configuration
SYSTEM MANAGEMENT
– Dual input power path function with input
current limiting and OV protection
– POR function with programmable masking
monitors all integrated supplies outputs
– Software and hardware reset functions
•
– 8-channel integrated A/D samples system
parameters with single conversion, peak
detection, or averaging operating modes
HOST INTERFACE
– Host can set system parameters and
access system status using I
2
C interface
– Interrupt function with programmable
masking signals system status modifiction
to host
– 3 GPIO ports, programmable as drivers,
integrated A/D trigger or buck converters
standby mode control
