DA9070

Ultra-Low Quiescent Current PMIC

General Description

DA9070 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, ultra-

low quiescent current (Iq) buck regulator and LDO/Load Switches, wide output voltage boost

regulator, analog battery monitor, watchdog and protection features in an I²C configurable compact

WLCSP package.

DA9070 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.

DA9070 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.

DA9070 includes dynamic power path management which automatically balancing current delivered

to the system and battery charging.

Suitable for small battery applications, the battery monitor facilitates on-demand battery voltage and

discharge current monitors to an external MCU’s ADC for supporting software fuel gauging.
