It supports a wide input range of 1.5 V to 5.5 V and a maximum continuous current of 1.5 A. The device uses a P-channel MOSFET with comparator-controlled chip enable to disable when CE exceeds VIN and enable when CE is lower. When used in an ORing configuration, two devices can pass the highest input voltage while blocking reverse current. Typical packaging is SC-70 (6), operating from –40°C to 125°C.",{"@graph":14,"@context":73},[15,34,56],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/technology/","Technology",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/lm66100-55-v-15-a-low-iq-ideal-diode-with-input-polarity-protection/393646/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/lm66100-55-v-15-a-low-iq-ideal-diode-with-input-polarity-protection/393646.png","ImageObject",300,407,{"name":42,"@type":43},"Bulrr","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-12","2026-09-26",true,{"@type":52,"interactionType":53,"userInteractionCount":55},"InteractionCounter",{"@type":54},"ViewAction",8,{"@type":57,"mainEntity":58},"FAQPage",[59,65,69],{"name":60,"@type":61,"acceptedAnswer":62},"What input voltage range and maximum continuous current does the LM66100 support?","Question",{"text":63,"@type":64},"The LM66100 operates over an input voltage range of 1.5 V to 5.5 V and supports a maximum continuous current of 1.5 A.","Answer",{"name":66,"@type":61,"acceptedAnswer":67},"How does the chip enable (CE) control the MOSFET state?",{"text":68,"@type":64},"The device compares the CE pin voltage to VIN: when CE is higher than VIN the device is disabled and the MOSFET is off;

The device contains a P-channel MOSFET that can operate over an input voltage range of 1.5 V to 5.5 V and can support a maximum continuous current of 1.5 A.  \nThe chip enable works by comparing the CE pin voltage to the input voltage. When the CE pin voltage is higher than VIN, the device is disabled and the MOSFET is off. When the CE pin voltage is lower, the MOSFET is on. The LM66100 also comes with reverse polarity protection (RPP) that can protect the device from a miswired input, such as a reversed battery.  \nTwo LM66100 devices can be used in an ORing configuration similar to a dual diode ORing implementation. In this configuration, the devices pass the highest input voltage to the output while blocking reverse current flow into the input supplies. These devices can compare input and output voltages to make sure that reverse current is blocked through an internal voltage comparator. The LM66100 is available in a standard SC-70 package characterized for operation over a junction temperature range of –40°C to 125°C.  \nDevice Information(1)  \n\n| PART NUMBER | PACKAGE | BODY SIZE (NOM) |\n| --- | --- | --- |\n| LM66100 | SC-70 (6) | 2.1 mm x 2.0 mm |\n\n(1) For all available packages, see the orderable addendum atthe end of the data sheet.  \nTypical Application  \nAn IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
