With 21 mOhm maximum RDS(on) at VGS=-10V, the device minimizes conduction losses in high-side load switching applications. The -15 A drain current rating and 29 W power dissipation capability support demanding battery management and power path control functions. The 28 nC total gate charge enables efficient switching at moderate frequencies. The DFN 3x3-8L package with exposed pad provides excellent thermal performance in a minimal footprint.","working_principle":"The AON5820 is a P-channel enhancement mode MOSFET. When the gate-source voltage (VGS) is more negative than the threshold voltage (VGS(th), -1.0V to -2.5V), an inversion layer forms in the P-body region under the gate oxide, creating a conduction channel between the source and drain. Current flows from source to drain when the drain is at a lower potential than the source. The RDS(on) of 21 mOhm at VGS=-10V is achieved through advanced trench technology with high cell density. In the off-state (VGS close to 0V), no inversion layer forms and the device blocks current up to the 30 V VDS rating. The body diode (inherent P-N junction between body and drain) conducts when the drain is forward-biased relative to the source, providing a natural freewheeling path.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>Source<\/td><td>Power<\/td><td>Source terminal<\/td><\/tr><tr><td>2<\/td><td>Gate<\/td><td>Input<\/td><td>Gate drive input<\/td><\/tr><tr><td>3<\/td><td>Source<\/td><td>Power<\/td><td>Source terminal<\/td><\/tr><tr><td>4<\/td><td>Drain<\/td><td>Power<\/td><td>Drain terminal<\/td><\/tr><tr><td>5<\/td><td>Drain<\/td><td>Power<\/td><td>Drain terminal<\/td><\/tr><tr><td>6<\/td><td>Drain<\/td><td>Power<\/td><td>Drain terminal<\/td><\/tr><tr><td>7<\/td><td>Drain<\/td><td>Power<\/td><td>Drain terminal<\/td><\/tr><tr><td>8<\/td><td>Source<\/td><td>Power<\/td><td>Source terminal<\/td><\/tr><tr><td>Pad<\/td><td>Drain<\/td><td>Power<\/td><td>Exposed thermal pad (drain)<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Laptop and tablet battery disconnect load switch<\/li><li>Smartphone power management high-side switch<\/li><li>Battery protection circuit power path control<\/li><li>DC-DC converter synchronous P-channel high-side<\/li><li>USB power delivery port power routing switch<\/li><\/ul>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>AOS<\/td><td>AON7403<\/td><td>DFN 3x3-8L<\/td><td>Older generation, higher RDS(on)<\/td><\/tr><tr><td>Infineon<\/td><td>BSB008NE2LX3<\/td><td>PQFN-8<\/td><td>30V P-ch, 9mOhm, higher current<\/td><\/tr><tr><td>Vishay<\/td><td>SI4465DY-T1-GE3<\/td><td>SOIC-8<\/td><td>30V P-ch, 22mOhm, leaded<\/td><\/tr><tr><td>onsemi<\/td><td>NTR4101PT1G<\/td><td>SOT-23-6<\/td><td>30V P-ch, 58mOhm, smaller<\/td><\/tr><tr><td>Texas Instruments<\/td><td>CSD25213W<\/td><td>SON-8<\/td><td>30V P-ch, 15mOhm, power block<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/6781","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/comments?post=6781"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/6781\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/media?parent=6781"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/categories?post=6781"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/tags?post=6781"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=6781"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
