TA7317P datasheet

 

Description :

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)

1. Supply voltage : Vcc = 60 V

2. Relay driver output current : Iout = 130 mA

3. Power dissipation : Pd = 500 mW
