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 Offset 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)
