General Description
DA9072 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, analog battery monitor, watchdog and protection features in
an I2C configurable compact WLCSP package.
DA9072 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
(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.
DA9072 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.
DA9072 includes dynamic power path management which automatically balances current delivered
to the system and for battery charging.
Suitable for small battery applications, the battery monitors facilitate on-demand battery voltage and
discharge current information to an external MCU’s ADC to support software-based fuel gauging.
