DA9068 Datasheet | Renesas

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 Smart Mirror™ 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 pletely controlled from the host by software writes to registers, which brings high flexibility to the design of applications. Key Features - Input voltage 2.8 V to...
