AS3658
Data Sheet Confidential
Power and Audio Management Unit for Portable Devices
1 General Description
The AS3658 is highly integrated power and audio
management unit. The AS3658 is designed to include
sophisticated audio features like high performance
audio DAC and ADC. It has several analog and digital
audio interface which are explained in detail in the
following sections. The AS3658 is an integrated solution
for power supply generation and monitoring, battery
management including charging.
2 Key Features
System Control
- Serial Control Interface
- On/Off Control Module with Boot-ROM / GPIO
- Reset Generation for system controller
- Programmable Interrupt Controller and Watchdog
- Low power off mode (9µA; 2.5V LDO on)
- 88 bit unique ID or Boot fuse array
- Reset with long ON-Keypress (SW-Interuptable)
- Touchscreen Interface (10 bit, interrupt)
Supply Voltage Generation
- 2 RF Programmable Low Noise LDOs (250mA) (1
LDO can be a current controlled switch for hotplug
(200mA ± 40%))
- 1 RF Programmable Low Noise LDO (400mA)
- 4 Programmable Dig. Low Power LDOs(200mA)
- 2 General Purpose PWM DC/DC step up converter
with three programmable current sinks (e.g. for-
white led); for current mode feedback is automati-
cally slected (DCDC_CURR1,2,3)
- 3 General Purpose high efficiency DC/DC step
down converter (DCDC 1 support DVM)
- 1 Low noise charge pump with 5V output voltage
- 1 Ultra Low Power 2.5V LDO (always on)
Current sinks
- 4 programmable(8-bit) from 0.15mA to 38.25mA
(±5% ) optional useable as GPIOs
- 3 programmable high voltage (15V) (8-bit) from
0.15mA to 38.25mA (±5% )
- internal PWM generator (extended time range)
(can control DCDC_CURR1,2,3)
10-bit 40µs Successive Approximation ADC
- Two external Inputs (ADC_IN1, ADC_IN2)
Battery Management
- Full featured chemistry independent step down
charger with Gas Gauge and Current limitation
- High Current (1.0A) Linear Charger with external
pass transistor (no step down charger)
- 0.1 Ω Battery switch for start-up and trickle charge
- Integrated USB charger up to 880mA (can be used
as wall adapter charger); current accuracy 440-
500mA for USB specification, in-circuit trimmable
(±1.2% trimsteps)
- Autonomous Battery Temperature Supervision
(0ºC-45ºC or 0ºC- 50ºC) for 10k and 100k NTC
- Charging Timeout (1h-8h in 30min steps)
- Charging in Stanby mode
- Completely Autonomous (no SW)
Power Management Features
- Wide Battery Supply Range 3.0…5.5V
- On-Chip Bandgap Tuning for High Accuracy (±1%)

- 32kHz output
- Backup Battery Charger and Switchover
Programmable System clock
- 1.6 MHz to 2.3 MHz with 100 kHz steps
Package
- BGA124 8x8mm, 0.5mm pitch (can be assembled
without micro via boards)
