DA9072

Ultra-Low Quiescent Current PMIC

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 (I_Q)

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 I_Qbuck converter

(efficient down to 10 µA load currents) and low I_QLDOs. 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.
