jf STK6865H Thick Moro Hybrid IC BIDIRECTIONAL. MoTOR DRIVER WITH BRAKE FUNCTION vl pot i on RS. eee +e CP Pe kes a ee TENTATIVE General Description The STK6865H is a bidirectional DC motor driver IC with brake function that is fabricated using our unique IMST (Insulated Metal Substrate Technology) struc- ture. The motor speed can be controlled by the PWM input signal as well as the MLA/ HH" slevel DC input signal. Features . Bidirectional motor driver and brake function, and protector against sinulta- neous application of input for forward/reverse drive. . Braking available with input open. . Braking available at forward drive mode ' . PWM input signaleused speed control available (25kHz max, ) Applications . Especially suited for driving DC brush-provided motors used in PPC's, print- ers, sewing machines, Maximun Ratings at Ta=25C Maximum Supply Voitage Vocmak Quiescent mode 7,8 = 9,10 *4 50~CiY Maximum Output Current Iomax DC 1 pulse 0.55ec.
