DA9061-A
DA9061-A is PMIC manufactured by Renesas.
PMIC for Applications Requiring up to 6 A
General Description
DA9061-A 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 car navigation, vehicle infotainment systems, automotive telematics and FPGA based applications.
DA9061-A Features three buck converters providing a total current of 6 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 DA9061-A. The four LDO regulators with programmable output voltage provide up to 300 m A.
Dynamic voltage control (DVC) allows dynamic control of DA9061-A 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.
DA9061-A 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 onkey. Several types of on-key presses can be detected to trigger different power mode transitions.
An integrated watchdog timer monitors the system.
Five GPIOs are able to perform system functions, including: keypad supervision, application buck, and timing-controlled external regulators/power switches or other ICs.
DA9061-A is also available as a consumer and industrial version DA9061.
