TA7780BN

The TA7780BN is a mechanism driver IC designed for IC logic control,which is especially suitable for a cassette tape recorder or other tape-audio system application.It is necessary to use with a particular programmable ROM array IC(PRA IC),which is logic controller,TC9312N(TOSHIBA Corp.)or similar.Features of the TA7780BN are:(1)preparing the directly drive capability for the following mechanism.RM(reel motor) CM(capstan motor) PL(plunger); (2)including the ASO(auto shut off)amplifier; (3)including the thermal-shut-down circuit; (4)including the motor torque change circuit,which has normal speed and high speed.; (5)operation supply voltage range:VCC(opr)=6~12V.

The absolute maximum ratings of the TA7780BN can be summarized as:(1)supply voltage:15V; (2)power dissipation:1200mW; (3)storage temperature:-55~150; (4)operating temperature:-25~75.

The electrical characteristics(Ta=25) of the TA7780BN can be summarized as:(1)quiescent supply current:3.1mA MIN. 3.8mA TYP. 5.7mA MAX.(ICCQ1);2.5mA MIN. 3.2mA TYP. 4.5mA MAX.(ICCQ2); (2)operation supply voltage:6V MIN. 13V MAX.If you want to know more information such as the electrical characteristics ,please download the datasheet in www.seekdatasheet.com .
