S/M POWER
Power Management for Cellular Systems
S / M P O W E R i s a h i g h l y i n t e g r a t e d Power and Battery
Management IC for mobile handsets and provides all power supply
functions for complete systems ranging from GSM over GPRS up to
EDGE smart phones and modules.
It has been optimized for usage with Infineon’s S-GOLD family based
systems in conjunction with cellular RF transceiver like SMARTi- DC+ and
SMARTi-SD as well as Infineon’s single chipsolution for Bluetooth.
The low power system performance required in market demanding
feature rich terminals can be ensured with this advanced power
management concept at best in class system costs and highest system
integration level.
