PMICS Elongate Battery Life

The configurable DA9053-multicore and DA9021 PMICs promise to optimize battery life and support major mobile graphics and application-processor families. The DA9053 handles high-end multicore-based applications and supports the ARM Cortex family while the DA9021 addresses lower-power, cost-sensitive apps. The DA9053 combines a 1.8A dual-input DC/USB power path router with a switching battery charger and includes support for multiple external memory configurations. The DA9021 offers the same configurable engine and includes a 1.3A single-input USB charger. Its internal regulators deliver approximately half the total current relative to DA9053.
