UTC1237 Description
UTC1237 is a monolithic integrated designed for protecting stero power amplifiers and loudsperkers.
UTC1237 Key Features
- Work stably within a wide power suppy voltage range(vcc=25 to 60V)
- Contain a relay driver(Max I 6=80mA)
- Work as either latching function or automatic resetting function by using pin 3. (in both overload detection and output
- Need only single power supply
- Both positive and negative output offset can be detected through the same pin.(output offset detection through pin 2)
- AC voltage can be detected.(for AC-power OFF mute through pin 4)
- The time delay from amplifier power ON to relay ON can be freely set by selecting external ponents.(For AC-power-ON mute
- The moment that amplifier-power is turned off, it can make relay broken OFF and then loudsperker disconnected from ampli
