DA9073规格书详情
General Description
DA9073 is a highly integrated, configurable, low quiescent current PMIC that integrates the most
common needs for wearables, home automation and low power battery applications.
The Power Management IC (PMIC) comprises a linear charger with Power Path management, ultralow 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 10 µA 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 configurable output voltage.
DA9073 provides charge current up to 500 mA to speed up the charge cycle. The charge profile is
programmable by external resistors or in software, allowing either stand-alone operation or host
control.
DA9073 includes dynamic power path management which automatically balancing current delivered
to the system and battery charging.
