Description
The TA7317P is protection circuit for OCL power amplifier and speaker.
Features
1. Over current detecting circuit
– Operation at the time of over load, such as a speaker terminal short.
2. DC voltage detecting circuit
– Operation at the time when positive or negative DC voltage (+- 1.1V of detection level) has generated at output terminals.
3. Muting circuit
– Transient noise protection when power is ON-OFF.
4. Relay driver circuit (Drive current of 130mA at Max.)
5. Operation by dual power supply.
Maximum Ratings ( Ta = 25’C)
