Resources for DA9073
Description
The DA9073 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, 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 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 of configurable output voltage.
DA9073 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.
DA9073 includes dynamic power path management which automatically balances the current delivered between the system and the battery.
Benefits
- Flexible charger supports slow and fast charging rates
- Low quiescent current buck regulator and LDOs extend battery life
- Integrated PMIC reduces power management footprint by 25% compared to discrete solutions
- Programmable power states optimize performance in operating modes and extend battery life in storage modes
