The DA9073 is a highly integrated, configurable, low quiescent current power management IC (PMIC) that integrates the most common needs for wearables, home automation and low power battery applications. The PMIC comprises a linear charger with power path management, ultra-low quiescent current (Iq) buck regulator and LDO/load switches, wide output voltage boost regulator, watchdog and protection features in an I²C configurable compact WLCSP package. DA9073 has several power-saving modes to increase battery life whether the product sits on the shelf or is in operation. Further savings in power are achieved with the ultra-low Iq buck converter that is efficient down to 10μA load currents and low Iq LDOs. The uncommitted inputs of LDOs can be connected to either the battery or buck output. The integrated, high-efficiency boost regulator supports both sensors and display supply needs with a wide range of configurable output voltage.
