TA7317P

The TA7317P is protection circuit for ocl power amplifier and speaker.Features of the TA7317P are:(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)opertion by dual power supply .

The absolute maximum ratings of the TA7317P can be summarized as:(1)supply voltage:60V; (2)power dissipation:500mW; (3)operating temperature:-25~75; (4)storage temperature:-55~150;(5)relay driver output current:130mA.

The electrical characteristics(Ta=25) of the TA7317P can be summarized as:(1)supply current:54mA TYP. (ICC ON);1.5mA MIN. 2.4mA TYP. 4mA MAX.(ICC OFF); (2)DC detector voltage:0.9V MIN. 1.1V TYP. 1.3V MAX. (+VDC);-0.9V MIN. -1.1V TYP. -1.3V MAX. (-VDC); (3)output voltage:1V TYP. 2V MAX.(VOUT(ON));50V (VOUT(OFF)).If you want to know more information such as the electrical characteristics ,please download the datasheet in www.seekdatasheet.com .
