AAT4681IDE-1-T1

DATA SHEET AAT4681 20mΩ P-Channel SmartSwitch for UMPC Battery Charging Applications General Description Features The AAT4681 SmartSwitch enables separate stand-alone AC adapter and PMU USB chargers to independently control a single low RDS(ON) power MOSFET between battery and system power output. A 20V version is available for multi-cell Li-ion applications and a 6V version is available for single-cell Li-ion applications. • Multi-Cell 20V Device and Single-Cell 6V Device • Dual Independent Gate Controls ▪ Independent Linear Regulator and SMPS Power Switch States are Maintained • 3mm x 3mm TDFN-10L package • Temperature Range: -40°C to 85°C The two P-channel power MOSFETs required in UMPC applications for controlling independent charger ICs can be consolidated to a single device, saving space and reducing cost. The single 20mΩ P-channel device in the AAT4681/-1 has four times lower RDS(ON) than the equivalent path resistance formed by two series devices. Applications • Smart Phones • Sub Notebooks ▪ Smartbooks ▪ Netbooks • Ultra-Mobile PCs • Wireless Media Devices Ordering options are available for multi-cell and singlecell Li-ion versions. For the single-cell application, a 6V device with dual independent gate control is available. For 2-cell and 3-cell applications a 20V ordinary P-channel device is available in the same package and pin configuration. Both devices are available in the TDFN-10L 3mm x 3mm package.
