... Demonstration Board for the SA57-IHZ INTRODUCTION The DB63R is designed to demonstrate the capabilities of the SA57 DC brush motor driver IC. This fully assembled demonstration allows the user to directly control the speed and direction of the motor. An onboard circuit controls the direction and provides four quadrant PWM signals to control the power outputs of the SA57. LEDs provide feed- back for motor control status and fault indications ...

... SA57 in all circumstances. The user must consider the worst case thermal and power dissipation conditions. Push-button switches 1 and 2 trigger latches (U4) for direction and enable control, respectively. Diodes D7 & D8 and resistors R24, 25, 29 & 30 provide a means of bypassing the DB63R control circuit. The 5V regulator, U3, pro- vides 5V to the SA57, the latches and the status LEDs. ...

... Figure 3 – Schematic ENHANCINg & BYPASSINg THE DB63R CONTROL CIRCUIT: Connector J5 allows the user to bypass many of the manual control features of the DB63R. A signal generator can control the duty cycle with a 2.5 to 7.5V signal, overriding the control potentiometer. A rising 5V edge on pin connector J5 will toggle the Direction or Enable latches, respectively. By jumping resistors R24 & R25, the latches are bypassed completely and the logic signals on pins 3 & ...
