PROTECTOR IC FOR STEREO POWER AMPLIFIER

DESCRIPTION UTC UPC1237
is a semiconductor integrated circuit designedfor protecting stereo power amplifiers and loudspeakers.

FEATURES * Wide supply voltage range of 25V~60V. * Contain a relay driver. (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.
