Product details of UPC 1237 HA PROTECTOR IC FOR STEREO POWER AMPLIFIER CIRCUIT SPEAKER PROTECTOR IC
- DESCRIPTION
- UTC UPC1237 is a semiconductor integrated circuit designed for 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.
