3.3.1. General Description
SM-POWER is a highly integrated Power and Battery Management IC for mobile handsets. It has been
specially designed for usage with S-Gold3. Although optimized for usage with the Infineon S-GOLD
baseband device it is suitable for the S-GOLDlite and the E-GOLD+ baseband devices as well. It also
supports the cellular RF devices like SMARTi-DC, SMARTi-DC+, SMARTi-SD and the Bluemoon
Single, Infineon’s single chip solution for Bluetooth. If used with S-GOLD3 it provides all power supply
functions (except for the RF PA) for a complete advanced GSM Edge smart phone minimizing external
device count.
Block Description
• Highly efficient step-down converter for main digital baseband supply including Core, DSP and
memory interface (External Bus Unit).
• Support of S-GOLD standby power-down concept
• Low-drop-out (LDO) regulators for Flash and mobile RAM memory devices
• Voltage independent switching of two SIM cards
• LDO regulators for baseband I/O supply
• LDO regulator for analog mixed-signal section of S-GOLD
• Low-noise LDO regulators for RF devices
• Supply for Bluemoon Single, Infineon’s single chip solution for Bluetooth
• Audio amplifier 8 Ohms for handsfree operation and ringing
• Charge Control for charging Li-Ion/Polymer batteries under software control
• Pre-charge current generator with selectable current level
• RTC regulator with ultra-low quiescent current
• USB interface support for peripheral and mini-host mode
• Backlight LEDs driver with current selection and PWM dimming function
• Two single LED driver outputs for signaling
• Vibrator driver with adjustable voltage
• Fully controlable by software via I2C – Bus
• Temperature and battery voltage sensors
• Interrupt channels for peripherals
• System debug mode
• VQFN 48 package with heat sink and non-protruding leads
• Compatible with the Infineon E-GOLD+ V2 and V3
SM-POWER is a further step on the successful E-Power product line with enhanced and optimized
functionality.
SM-POWER features a baseband supply concept with a DC/DC step-down converter cascaded by two
linear regulators
–SM-POWER’s DC/DC converter makes up to 40 % reduction of battery current for smart phone
functions (e.g. organizer functions, games, MP3 decoding) possible.
– SDBB has high efficiency up to 95% and also a power save mode.
– Memory Interface is directly supported by the SDBB
– SDBB can also act as main supply voltage for E-GOLD+ or S-GOLDlite baseband devices.
– For S-GOLD two linear regulators for DSP and Core are cascaded after the SDBB.
