Qorvo ACT81460VM101 Low Power PMIC

Qorvo ACT81460VM101 Low Power Power Management IC (PMIC) is designed for battery-operated systems and is suitable for various processor applications. This PMIC features a low standby current that prolongs battery life between charges, especially in applications requiring long or low-power mode durations. The highly efficient modules enhance battery run time during normal operating modes. The number of regulators turned off or left on at low power modes is configurable, offering flexibility to optimize system efficiency. This PMIC includes four DC-DC converters with integrated power FETs and three low-dropout (LDO) regulators. Other features are configurable power sequencing combinations, startup timing, output voltage settings, fault monitoring, interrupt control, programmable GPIO options, and more.

The ACT81460VM101 PMIC is pre-configured at the factory with default configuration settings via the standard I2C interface to suit individual system requirements. This device comes with the ability to sequence external power supply rails as part of the power-up sequence by using GPIOs.

The Qorvo ACT81460VM101 PMIC is available in a 3.3mm x 3.3mm WLCSP-49 package with an optimized pinout for easy PCB routing.
