• SMPS voltage control for optimized PA Vdd and bias control for
maximum talk-time performance
powerOne Series PM6650 Device Description
The MSM6250 device also interfaces directly with
• SMPS voltage generation for white LEDs used for Color LCD
backlighting
the first in QCT's new powerOne series power
management ICs, the PM6650 device. The PM6650
solution provides battery management and charging
• USB OTG transceiver included
• Configurable Multi-Purpose Pins (MPPs) for digital or analog I/O
utility functions such as general-purpose LED drivers, USIM or SD-
Card-level translation, programmable resistors or digital switches
• High-current LED driver for Camera Flash application
• Speaker driver with programmable gain, turn-on time, and muting;
single-ended or differential operation (drives external
8-ohm speakers with volume-controlled 500 mW)
functions, including a USB charging option, and
voltage regulation for the various MSM power
regimes, the radioOne chipset and all other MSM-supported peripheral
features. Exceptional power savings are realized through the use of a
switch-mode power supply (SMPS) from the PM6650 device to regulate
the MSM's core voltage. All voltages generated for the MSM and
radioOne RF chips are optimized for handset system control with the
MSM6250 system software.
• Real-time clock for tracking time, calendar functions, programmed
durations and generating associated alarms
• TCXO Control provides warm-up, synchronization, and buffering of
the TCXO signal for optimal QPH/catnap timing and maximum
standby-time performance
The PM6650 chip offers unparalleled integration of power
management functions for CDMA terminals, affording a tremendous
savings in size and BOM for handset design. Integrated features
include a color LCD backlight driver, USB OTG transceiver, R-UIM and
SD Card interface, PA bias control, speaker driver, real-time clock,
TCXO control, and various general housekeeping and interface
functions, making the PM6650 chip the ideal power management
solution for feature-rich terminals.
• Automated power-on recovery from sudden momentary power loss
• Support for coin cell back-up battery (including charging)
• 84 BCCS dual-row bump chip carrier package (7 mm x 7 mm)
