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 ORDERING INFORMATION
