CHIPSET SOLUTION
powerOne Series PM6650 Device Description
The MSM6150 device also interfaces directly
with the first in QCT's powerOne series power
management ICs, the PM6650 device. The
PM6650 solution provides battery management
and charging 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 MSM6150 system
software.
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.
PM6650 Key Features
• Complete battery management, voltage regulation, general
housekeeping and user-interface functions for CDMA terminals
• Compatibility with QUALCOMM's radioOne ZIF chipset (and all
MSM-supported peripheral features)
• Trickle, fast, constant voltage and pulsed charging modes for the
main battery, with current monitoring for over-current protection
• Available USB charging option with automatic charging source
selection
• Complex power management, including MSM power-on
sequencing and control and dynamic voltage scaling for
maximum power savings
• SMPS provides high-efficiency voltage regulation for the MSM
core, 1.8 V high-speed external bus interface and memory circuits
• SMPS voltage control for optimized PA Vdd and bias control for
maximum talk-time performance
• SMPS voltage generation for white LEDs used for color LCD
backlighting
• USB OTG transceiver
• 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)
• Real-time clock for tracking time, calendar functions and
programmed durations and for generating associated alarms
• TCXO control with warm-up, synchronization and buffering of the
TCXO signal for optimal QPCH/catnap timing and maximum
standby-time performance
• Automated power-on recovery from sudden momentary power
loss
• Coin cell back-up battery support (including charging)
• 84 BCCS dual-row bump chip carrier package (7 mm x 7 mm)
