UPC1237 Overview
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
