Datasheet NTE7100 (NTE Electronics)

NTE7100 Integrated Circuit Protector IC for Stereo Power Amplifier Description:
The NTE7100 is a monolithic integrated circuit in an 8–Lead SIP type package designed for protecting stereo power amplifiers and loudspeakers.
Features:
D Work Stably Within a Wide Power Supply Range: VCC = 25V to 60V D Contains a Relay Driver: I6 = 80mA max D Pin3 can be used for Either a Latching Function or Automatic Resetting Function (In Both Overload Detection and Output Offset Detection, Either Function can be Selected) D Single Power Supply D Both Positive and Negative Output Offset can be Detected Through the Same Pin (Output Off- set Detection Through Pin2) D AC Voltage can be Detected (For AC–Power–OFF Mute Through Pin4) D The Time Delay from Amplifier Power ON to Relay ON can be Freely Set by Selecting External Components. (For AC–Power–ON Mute Through Pin7)
