Description: The ACT8846 is a complete, cost effective, and highly-efficient Active PMUTM power management solution optimized for the power, voltage sequencing and control requirements of Rockchip RK31x8 application processor family. The ACT8846 features four fixed-frequency, current mode, synchronous PWM step-down converters that achieve peak efficiencies of up to 97%. These regulators operate with a fixed frequency of 2.25MHz, minimizing noise in sensitive applications and allowing the use of small external components. These buck regulators supply up to 2.8A of output current and can fully satisfy the power and control requirements of the multi-core application processor. Dynamic Voltage Scaling (DVS) is supported either by dedicated control pins, or through I2C interface to optimize the energy per-task performance for the processor. This device also include eight low-noise LDOs (up to 350mA per LDO), one always-on LDO and an integrated backup battery charger to provide a complete power system for the processor. The power sequence and reset controller provides power-on reset, SW-initiated reset, and power cycle reset for the processor. It also features the watchdog supervisory function. Multiple sleep modes with autonomous sleep and wake-up sequence control are supported. The thermal management and protection subsystem allows the host processor to manage the power dissipation of the PMU and the overall system dynamically. The PMU provides a thermal warning to the host processor when the temperature reaches a certain threshold such that the system can turn off some of the non-essential functions, reduce the clock frequency and etc to manage the system temperature. The ACT8846 is available in a compact, TQFN66-48 package.
