Datasheet AS3710 Triple Buck High Current PMIC with Charger 1 General Description The AS3710 is a compact System PMU with integrated battery charger and back light driver. The device offers advanced power management functions. All necessary ICs and peripherals in a battery powered mobile device are supplied by the AS3710. It features 3 DCDC buck converters as well as 8 low noise LDOs. The different regulated supply voltages are programmable via the serial control interface. 4MHz operation with 1uH coils are reducing cost and PCB space. The three step-up converter generate voltages for e.g.the backlight, classD amplifier, USB host support or LCD display supply. Both constant voltage for e.g. OLED supply as well as constant current white LED backlight operations with three current sinks are possible. An internal voltage protection is limiting the output voltage in the case of external component failures. AS3710 contains a linear or switching mode Li-Ion battery charger with constant current and constant voltage. The maximum charging current is 1.5A. An integrated battery switch and an optional external switch are separating the battery during charging or whenever an external power supply is present. With this switch it is also possible to operate with no or deeply discharged batteries. A programmable current limit 100mA - 2.5A can be used to control the maximum current used from a USB supply or charger input. Additional features are a 30V OV protection and battery temperature supervision. The single supply voltage may vary from 2.7V to 5.5V. 2 Key Features Voltage Generation 3 DCDC step down regulators 2-4MHz - DVM 0.6V-3.3V;1x 1.2-1.5A, 2x 0.7-1A - 60µA quiescent current - 2A with combined DCDC 2 & 3 2 analog low noise LDOs, 6 digital LDOs - 2x 1.2-3-3V, 6x 0.9-3.3V 150-300mA - 30µA quiescent current low power mode 1 ultra low power always on LDO 2.5V, 10mA Power supply supervision 4sec and 8sec emergency shut-down Stand-by function with voltage selection HV Backlight Driver 3x step up with external transistor - e.g. Voltage control mode and over-voltage protection 3 programmable current sinks max. 40mA Possible external PWM dimming input DLS, CABC Battery Charger Programmable trickle charging 25-220mA Programmable constant current charging up to 1500mA Programmable constant voltage charging 3.9V-4.25V Charger time-out and temperature supervision Selectable current limitation for USB mode Integrated battery switch & ideal diode linear mode External battery switch control switching mode External 30V OV protection Supervisor Automatic battery monitoring with interrupt generation and selectable warning level Automatic temperature monitoring with interrupt generation and selectable warning and shutdown levels Real Time Clock Ultra low power 32kHz oscillator Sec and minute counter, auto wake-up Programmable alarm Repeating alarm seconds, minutes, 2 minutes, or 8 minutes 32kHz clock output to peripheral <1µA total power consumption General Purpose IOs 10-bit general purpose ADC input Wake-up/sleep and DVM input PWM DLS, CABC dimming input Status output for charger, low battery, power good and step-up over-current Q32k clock output Interrupt output PWM output Step-up feedback input 1 - 98 OTP programmable BOOT Sequence Programmable regulator default voltages Programmable start-up sequence General Purpose ADC 10-bit resolution Several internal / external sources - VUSB, VSUP, CHGIN, VBAT - GPIOx, CURRx - XOUT32K, SENSEN_SU1, FB_SU3 - Chip temperature Figure AS3710 Block Diagram Control Interface I2C control lines, including watchdog ON input Bidirectional reset, with selectable delay Ultra low power standby mode Power-On Reset Circuit Packaging QFN56 7x7mm 0.4mm pitch 3 Application The device is suitable for Portable Media Players, Portable Navigation Devices, E-Books, Mobile Internet Devices, and Tablet PCs.. 2 - 98 AS3710 2V1 Datasheet - Contents Contents 1 General Description 1 2 Key Features 1 3 Application 2 4 Pin Assignments 4 Pin Descriptions 4 5 Absolute Maximum Ratings 7 6 Electrical Characteristics 8 7 Typical Operating Characteristics 9 8 Detailed Description - Power Management Functions 10 DCDC Step-Down Converter 10 Analog LDO Regulators 16 Digital LDO Regulators 18 Low power LDO V2_5 Regulators 20 DCDC Step-Up Converter 21 Current Sinks 27 Charger 28 9 Detailed Description - System Functions 36 Start-up 36 Reset 38 Stand-by 40 Internal References 41 GPIO Pins 42 Supervisor 45 Watchdog 46 Interrupt Generation 47 10-Bit ADC 48 Real Time Clock 50 2-Wire-Serial Control Interface 51 10 Register Overview 53 11 Application Information 91 12 Package Drawings and Markings 94 13 Ordering Information 97 3 - 98 AS3710 2V1 Datasheet - Pin Assignments 4 Pin Assignments Figure Pin Assignments Top View 4 - 98 AS3710 2V1 Datasheet - Pin Assignments Pin Descriptions Table Pin Descriptions Pin Name Number AS3710 1 EXTBATSW XOFF CHGIN 4 VSUP_CHG CHGOUT VSUP_SD3 LX_SD3 FB_SD3 FB_SD2 LX_SD2 11 VSUP_SD2 FB_SD1 LX_SD1 14 VSUP_SD1 CURR1 CURR2 CURR3 18 VINLDO78 LDO8 LDO7 21 VSUP_GPIO XRES GPIO1 GPIO2 GPIO3 GPIO4 LDO2 31 VINLDO123 Datasheet - Ordering Information 13 Ordering Information The devices are available as the standard products shown below.
