NUS3046MN

NUS3046MN Overvoltage Protection IC with Integrated MOSFET This device represents a new level of safety and integration by combining the NCP346 overvoltage protection circuit (OVP) with a 30 V P−channel power MOSFET. This IC is specifically designed to protect sensitive electronic circuitry from overvoltage transients and power supply faults. During such hazardous events, the IC quickly disconnects the input supply from the load, thus protecting the load before any damage can occur. The OVP IC is optimized for applications that use an external AC−DC adapter or a car accessory charger to power a portable product or recharge its internal batteries. It has a nominal overvoltage threshold of 5.5 V which makes it ideal for single cell Li−Ion as well as 3/4 cell NiCD/NiMH applications. Features Overvoltage Turn−Off Time of Less Than 1.0 ms Accurate Voltage Threshold of 5.5 V, Nominal Control Input Compatible with 1.8 V Logic Levels −30 V Integrated P−Channel Power MOSFET Low RDS(on) = 66 mW @ −4.5 V Low Profile 3.3 x 3.3 mm DFN Package Suitable for Portable Applications Maximum Solder Reflow temperature @ 260°C This is a Pb−Free Device Benefits Provide Battery Protection Integrated Solution Offers Cost and Space Savings Integrated Solution Improves System Reliability Applications Portable Computers and PDAs Cell Phones and Handheld Products Digital Cameras http://onsemi.com 8 1 DFN8 CASE 506AL MARKING DIAGRAM 1 3046 AYWW G G 3046 = Device Code A =...
