DA9062
DA9062 is PMIC manufactured by Renesas.
Description
DA9062 is a power management integrated circuit (PMIC) optimized for supplying systems with single- and dual-core processors, I/O, DDR memory, and peripherals. It targets mobile devices, medical equipment, IVI systems, and FPGA based applications.
DA9062 features four buck converters providing a total current of 8.5 A. High efficiency is achieved over a wide load range with PFM mode available for low power or sleep modes. All power switches are integrated, therefore, external Schottky diodes are not required. Furthermore, low-profile inductors can be used with DA9062. Two of the buck converters can be used in a dual-phase configuration, and one can be used as a DDR VTT supply. The four LDO regulators with programmable output voltage provide up to 300 m A.
Dynamic voltage control (DVC) allows dynamic control of DA9062 supply voltages according to the operating point of the system. It is controlled by writing directly to the registers using the I2C patible 2-wire interface or the GPIOs.
DA9062 features a programmable power sequencer that handles start-up and shutdown 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.
The real-time clock (RTC), with an external 32 k Hz crystal oscillator, provides time keeping and alarm functions. Additionally, the integrated watchdog timer monitors the system.
Five GPIOs are able to perform system functions, including: keypad supervision, application wakeup, and timing-controlled external regulators/power switches or other ICs.
DA9062 is also available as an automotive AEC-Q100 Grade 2 version.
