Beschreibung

The ACT81461 is a low power PMIC (power management integrated circuit) that is specifically designed for battery operated systems and is suitable for a variety of processor applications. It features very low standby current that prolongs battery life between charges, especially in applications requiring long stand by or low power mode durations. It is a highly efficient PMIC that also enhances battery run time during normal operating modes. The number of regulators that can be turned OFF or left ON during low power modes is configurable and offers users flexibility to optimize system efficiency. The IC includes four DC/DC converters with integrated power FETs, three low-dropout regulators (LDOs), and three load switches. Two of the DC/DC converters are step down buck regulators, one is a step up/down buckboost regulator and the fourth is a high voltage step-up boost regulator capable of providing up to 20V. Each regulator can be configured for a wide range of output voltages through the I2C interface.The ACT81461 is highly configurable. It offers configurable power sequencing combinations, startup timing, output voltage settings, fault monitoring,interrupt control, programmable GPIO options,and many more features. The device is pre-configured at the factory with default configuration settings that can be further adjusted though firmware via the standard I2C interface to suit individual system requirements. The IC also features the ability to sequence external power supply rails as part of the power up sequence by using GPIOs.The ACT81461 PMIC is available in a 3.33mm x 3.28mm, 49 ball WLCSP package
