UPC1237 LINEAR INTEGRATED CIRCUIT PROTECTOR IC FOR STEREO POWER AMPLIFIER DESCRIPTION
UTC
UPC1237
is a semiconductor integrated circuit designed for protecting stereo power amplifiers and loudspeakers. SIP-8
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
