Data Sheet AS3605 Multi-Standard Power Management Unit 1 General Description The AS3605 is a highly-integrated CMOS power management device designed specifically for portable devices such as mobile phones, PDAs, CD players, digital cameras and other devices powered by 1-cell Li-Ion battery. It can be used for any mobile phone handset standards such as CDMA, WCDMA, GSM, GPRS, EDGE, UTMS and other Japanese or American standards. The device incorporates low dropout regulators LDOs , a DC/DC converter, a complete battery charger, and an audio power amplifier on one die. The linear analog LDOs feature extremely high performance regarding: - Noise typ 30µVRMS from 100Hz to 100kHz - Line/Load Regulation < 1mV static, < 10mV transient - Power Supply Rejection > 70dB 1kHz The integrated Step Down DC/DC Converter does not require an external Schottky diode yet provides very high efficiency up to 95% throughout the whole operating range. 5 programmable current sources are included to control LED brightness. A low-distortion audio power amplifier 1 Watt 8Ω supports handsfree operation and HiFi ring-tones. The device also features a battery charger including automatic trickle charging, and programmable constant voltage and current charging. The AS3605 is controlled via a serial interface and integrates all necessary system specific functions such as Reset, Watchdog, and Power-On Detection. Output voltages and start-up timings can be programmed via the internal OTP. 2 Key Features 8 Programmable High Performance LDOs - Four RF Low-Noise LDOs to 3.35V, 150mA - Two Analog Low-Noise LDOs to 3.35V, 250mA - One SIM Low-Power LDO or 3.0V, 20mA - One Low-Power LDO 2.5V, 10mA Programmable High Efficiency DC/DC Converter - Step Down to 3.4V, up to 500mA with 2.2MHz Stereo Audio Power Amplifier - 0.5W 4Ω Stereo 1W 8Ω Bridged - Digital Volume Control, 3dB Steps - Click- and Pop-Less Start-Up and Power-Down Battery Charger - Automatic Trickle Charging - Programmable Constant Current Charging - Programmable Constant Voltage Charging - Safety Functions Low Battery Shutdown - Over- and Under-Temperature Charge Disable - Operation without Battery - 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 - No-Battery Detection Momentary Power Loss Detection - Battery Supply Short-Interruption Detection <200ms e.g., due to a dropped phone Five Programmable Current Sources 3x40mA, 2x160mA - 8-Bit to 160mA - Buzzer, Vibrator, LEDs Charge Pump 1:1 and 1:2 mode 60mA VBAT OTP programmable boot sequence Wide Battery Supply Range to 5.5V Three Programmable General Purpose I/O Pins On-Chip Bandgap Tuning for High Accuracy ±1% Integrated Programmable Watchdog 16 to 4080ms Programmable Reset 0 to 70ms Shutdown Current typ <10µA 2.5V Always On Overcurrent and Thermal Protection Watt Power Dissipation = 70ºC Packaging QFN40 5x5mm, 0.4mm pitch 3 Application Multi-standard power management for mobile phones, PDAs, and any other 1-cell Li+ powered devices. 1 - 73 AS3605 1v2 Data Sheet - Application Figure AS3605 Block Diagram.
