General Description
DA9068 is a power management IC (PMIC) optimized for supplying systems with multi-core CPUs,
I/O, DDR memory, and peripherals.
DA9068 contains an integrated Power Management Controller (PMC) for multiple power supplies
(programmable LDO regulators and buck converters). DA9068 features a programmable power
sequencer that handles start-up and shut-down sequences. Power mode transitions can be triggered
with software control, GPIOs, or with the on-key. Several types of on-key presses can be detected to
trigger different power-mode transitions.
All 25 linear regulators use Dialog’s SmartMirror™ dynamic biasing technique which maintains high
performance over a wide range of operating conditions and a power saving mode to minimize the
quiescent current. The regulators have output voltages programmable via the device control
interface.
The eight buck converters do not require external Schottky diodes and offer a power saving mode
(PFM mode) for optimal light load efficiency. The DC-DC converters use either 2 MHz or 3 MHz
switching frequency giving high efficiency and allowing the use of small external inductors (down to
1 µH).
Dynamic voltage control (DVC) allows supply voltages of DA9068 to be controlled dynamically
according to the operating point of the system. The control can be realized via direct register writes
through the I2C interface or via GPIOs.
The real-time clock (RTC) with an external crystal oscillator provides time-keeping and alarm
functions. In addition, a watchdog timer is included for system monitoring purposes.
Furthermore, DA9068 contains a general purpose 12-bit analog-to-digital converter (GPADC) and
general purpose I/O pins (GPIO). These modules are implemented to support functions such as
battery voltage supervision and device over-temperature protection.
DA9068 can be completely controlled from the host by software writes to registers, which brings high
flexibility to the design of applications.
