**Descriptions:**  
The UPC1230H2 is a protection IC designed for audio amplifiers to prevent damage to speakers from DC offset or excessive AC signals. It includes built-in detection circuits for both DC and AC faults, triggering a relay to disconnect the speakers when a fault is detected.  

**Features:**  
- Dual-channel protection (supports stereo systems)  
- Built-in DC and AC detection circuits  
- Low standby current consumption  
- Relay drive output with high current capability  
- Adjustable AC detection threshold via external resistors/capacitors  
- Thermal shutdown protection  
- Compact SIP (Single In-line Package) design  

This IC is commonly used in audio amplifiers to enhance system reliability.
