DESCRIPTION
An innovative circuit that facilitates low-loss sensing of the output current has been implemented. An on-board PWM oscillator and comparator are used to convert an analog signal into PWM direction of rotation and magnitude for motor control applications. TTL or CMOS digital inputs allow direct external control in 2-quadrant or 4-quadrant modes. FIGURE 1. BLOCK DIAGRAM 7%% 7 74 7 $18. 18. %*4"#-& %*3 2 2 *4&/ 73&' '"6-5 5-*. $POUSPM MPHJD BOE 18.
