ON Semiconductor introduces new positive and negative overvoltage protection controller .
The NCP372 positive and negative overvoltage protection controller is able to disconnect systems from its output pin when wrong operating conditions are detected at it’s input.
The NCP372 overvoltage protection offer both positive and negative overvoltage protection up to ±28 V.
The NCP372 is able to instantaneously disconnect the output from the input due to integrated Low Ron Power NMOS, if the input voltage exceeds the overvoltage threshold (OVLO) or undervoltage threshold (UVLO).
The NCP372 provides a negative going flag (FLAG) output, which alerts the system that a fault has occurred.
NCP372 device has ESD−protected input (15 kV Air) when bypassed with a 1.0 _F or larger capacitor.
NCP372 is ideal to use in portable applications like : cell phones , camera phones , digital still cameras , personal digital assistant , MP3 players ,GPS for overvoltage protection .
Other features of the NCP372 positive and negative overvoltage protection chip are : overvoltage protection up to 28 V , negative voltage protection down to −28 V , reverse current blocking , On−Chip Low RDS(on) NMOS transistor , Overvoltage Lockout (OVLO) , Undervoltage Lockout (UVLO) , Soft−Start , alert FLAG Output , shutdown EN Input , ESD Ratings: Machine Model = B Human Body Model = 2 .
