| AS3604 Preliminary Product Brief and AS3603/04 Delta Sheet, Confidential austriamicrosystems Preliminary Product Brief and AS3603/04 Delta Sheet, Confidential AS3604 AS3603 with Momentary Power Loss Detection, synchronous DCDC and increased driving capability of the LDOs General Description The AS3604 is based on the architecture of the AS3603. It has additional functions like momentary power loss detection, a synchronous DCDC buck converter, charger resume operation and increased driving capability of the LDOs. - - - - - - Programmable Constant Voltage Charging Programmable Pulse Charging Safety Functions (Low Battery Shutdown) Operation without Battery No-Battery Detection Can regulate the current through the battery or from the charger - Charger Input Overvoltage protection (6V) - Shutdown even with connected charger - Charger Resume operation - Charger Interrupts (Inserted, Removed, Overvoltage, Resume) Four 8-Bit Programmable Current Sources (0.625mA to 160mA) support: - Buzzer - Vibrator - LEDs Wide Battery Supply Range 3.0 to 5.5V Four General Purpose Switches (1 and 2 ) Three Programmable General Purpose I/O Pins On-Chip Bandgap Tuning for High Accuracy (1%) Integrated Programmable Watchdog (7.5 to 1900ms) Programmable Reset (10 to 110ms) Shutdown Current typ 7A (2.5V Always On) Overcurrent and Thermal Protection 0.35 CMOS Solution 48-Pin, 6x6mm QFN Package (0.4mm pitch) 2.1 Watt Power Dissipation @ TAMBIENT = 70C Almost Pin Compatible to AS3603 (only one pin changed) Key Features The AS3604 features all the functions of the AS3603 with the following additions (marked with boldface italcs): Momentary Power Loss Detection - Detect a short interruption (<200ms) of the battery supply (e.g. due to a dropped phone) Ten Programmable High Performance LDOs - Two Digital Low-Power LDOs (0.75 to 2.5V, 200mA; 250mA up to 1.4V) - Three RF Low-Noise LDOs (1.85 to 3.4V, 200mA) - Two RF Low-Noise LDOs (1.85 to 3.4V, 150mA) - One SIM Low-Power LDO (3.0V, 20mA) - One Periphery Low-Noise LDO (2.5 to 3.2V, 200mA) - One Low-Power LDO (2.5V, 10mA) Programmable High Efficiency DC/DC Converters - Step-down: 0.8V-3.4V, up to 500mA with 2.2MHz operating frequency and small external coil (2.2uH)) - Step Up: 15V, 45mA, (for White LEDs) Stereo Audio Power Amplifier - 0.5W @ 4 -Stereo - 1W @ 8 -Bridged - Digital Volume Control, 3dB Steps - Click- and Pop-Less Start-Up and PowerDown Complete Chemistry-Independent Battery Charger - Integrated Fuel Gauge - Automatic Trickle Charging - Programmable Constant Current Charging Application Multi-standard power management for mobile phones, PDAs, and 1-cell Li+ or 3 to 4-cell Ni-MH powered devices. www.austriamicrosystems.com (ptr) Revision 1.0 / 20060505 1-4 AS3604 Preliminary Product Brief and AS3603/04 Delta Sheet, Confidential austriamicrosystems 1 Block Diagram Figure 1 -
