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.
