(Max. I6=80mA) Work as either latching function or automatic resetting function by using pin 3. (In both overload detection and output offset detection, either function can be selected.) Single power supply Built-in output offset detection function. Both positive and negative output offset can be detected through pin2 AC voltage can be detected Time delay function. The time delay form amplifier power ON to relay ON can be freely set by selecting external components The moment that amplifier-power is turned off, it can make relay broken OFF and then loudspeaker disconnected for amplifier to prevent a shock off noise  PIN DESCRIPTION PIN NO.
