PROTECTOR IC FOR STEREO

POWER AMPLIFIER

DESCRIPTION

UTC UPC1237 is a semiconductor integrated circuit designed

for protecting stereo power amplifiers and loudspeakers.

FEATURES

* Wide supply voltage range of 25V~60V.

* 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.
