1 SEMICONDUCTOR TECHNICL DT BIPOLR LINER INTEGRTED CIRCUIT BI-DIRECTIONL DC MOTOR DRIER is a monolithic integrated circuit designed for driving bi-directional DC motor with braking and speed control, and suitable for the loading motor driver of CR, Cassette tape recorders systems. The speed control can be achieved by adjusting the external voltage of the speed control pin. P F d Q D G I J H1 H L B T FETURES Brake is applied when stopping the motor. Built-in Function absorb rush current generated by reversing and braking. Power transistor can handle a large current (1. Max.) External motor speed control pin. Stable operation during mode changes either from forward to reverse or vice versa. Interfaces with CMOS devices. Operation supply voltage range : CC =. 1. M N DETIL "" MX:.5 MIN:.

(refer to the truth table) 3) If pin 5=pin =L or pin 5=pin =H, the stops supplying the power to motor while absorbing counter EMF from the motor as a brake.. RUSH CURRENT BSORBING CIRCUIT If a high voltage generated during reversing operation is applied across pin and pin 1, an internal comparator activates the rush current absorbing circuit. 3. DRIER CIRCUIT In the forward mode, the drive stage supplies a load current to the motor from pin to pin 1. In the reverse mode, it supplies the current from pin 1 to pin. The output voltage (out) applied to the motor is given by the followings ; OUT = ZD - CE (sat), where ZD : a zener voltage applied to pin. If pin is left open, the output voltage is given by the followings ; OUT = CC1 - CE (sat, pnp)- F - CE (sat) = CC1-1. (I OUT =1m) 5/
