NUS1204MN
Overvoltage Protection IC
with Integrated MOSFET
This device represents a new level of safety and integration by
combining the NCP304 overvoltage protection circuit (OVP) with a
−12 V P−Channel power MOSFET. It 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 using 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 4.725 V which makes it ideal for single cell Li−Ion as well as 3/4
cell NiCD/NiMH applications.
Features
• OvervoltageTurn−Off Time of Less Than 20 ms
• Accurate Voltage Threshold of 4.725 V, Nominal
• High Accuracy Undervoltage Threshold of 2.0%
• −12 V Integrated P−Channel Power MOSFET
• Low R_DS(on) = 75 mW @ −4.725 V
• Low Profile 2.0 x 2.0 mm WDFN Package Suitable for Portable
Applications
• Maximum Solder Reflow Temperature @ 260°C
• This device is manufactured with a Pb−Free external lead finish only.
Benefits
• Provide Battery Protection
