Dialog Semiconductor DA9070 | Demoboard DA9070 / DA9073 Demo Board

Description

DA9070is 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.DA9070has 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 10μA 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 500mA 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.
