The new devices use the latest AlphaMOS™ technology to accomplish very low RDS(ON) along with 4kV ESD protection to enhance battery pack safety. AON6810 and AON6812 use a bottom-exposed DFN5x6 package for enhanced thermal capability. The AON6812 features a low 8mOhm max total RSS (source-to-source) resistance at 10V drive. Rated with a 30V breakdown voltage, it is capable of charging and discharging a laptop battery pack with the least amount of power loss and heat dissipation. The AON6810 provides an extra level of protection with an internal temperature sense diode that provides first-hand thermal information to the battery control IC. By utilizing the temperature sense pins of AON6810, designers can accurately monitor the MOSFETs' thermal condition in a real time basis to prevent any abnormal overheating.
To meet the demand of ultra-thin battery packs, the AOC4810 takes advantage of AOS's innovative Micro-DFN package, which features an ultra-low profile of only 0.4mm. Unlike conventional CSP (chip scale packaging), the Micro-DFN eliminates the risk of die chipping by encapsulating the silicon to provide full protection to the die as well as providing excellent moisture isolation. When board space is a key concern, AOC4810 provides a great option to further enhance power density. With dimensions of only 3.2mm x 2mm, AOC4810 offers a maximum RSS level of 8.8mOhms to minimize conduction loss and heat dissipation.
