MOBILE POWER MANAGEMENT UNIT
multimode 300-mA switching regulators with high efficiency over wide-load range peak efficiency load efficiency load Programmable output voltages 0.9V-2.5V LDOs with programmable output voltage analog LDOs with 30-V noise 70-dB PSRR Ultra dropout Ultra low-power mode sleep cycle CC/CV USB/wall adapter charger with auto-detection Battery monitoring with highly accurate coulomb counter-based fuel-gauge Programmable CC/CV backup battery charger Real-time clock with programmable alarm Accessory detection I2C-compatible serial interface Low-profile 48-pin, PQFN package
SUMMARY BENEFITS
High level integration reduces power battery management bill materials. Multimode buck switchers offer best-in-class efficiency. Switchers high-operating frequency enables low-profile, small footprint magnetic components selection. Output voltage programming switchers LDOs offers flexibility use. Extended system active/idle mode operations time achieved high-efficiency, low-quiescent current mode operation. Charger input voltage enables adoption inexpensive AC/DC adapters. Higher reliability flexibility system operation with programmable start-up sequencing. High-performance, noise-free linear charger with fast/trickle charge modes. Highly accurate fuel gauge provides true battery condition reporting.
