UPC1237 Description

UTC UPC1237 is a semiconductor integrated circuit designed for protecting stereo power amplifiers and loudspeakers.

UPC1237 Key Features

  • Wide supply voltage range of 25V~60V
  • Contain a relay driver. (Max. I6=80mA)
  • Work as either latching function or automatic resetting function
  • 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 ponents
  • The moment that amplifier-power is turned off, it can make relay broken OFF and then loudspeaker disconnected for amplif
  • ORDERING INFORMATION
  • MARKING
