... DC motor system, motor speed is controlled while controlling torque. The primary application is drive con- trol for portable drills while providing overload protection. The main function of the HIP9021IB is to produce a pulse width modulated square wave signal which drives the gate of an N-Channel Power MOSFET. The duty-cycle is deter- mined by the setting of an external potentiometer at the TRIGGER (speed control) input ...

... The framed pulse duty cycle and delay, in percent, are measured in reference to the gate pulse which is set at 50% duty cycle. The Delay output framed pulse delay is one-half of the difference of the gate pulse width minus delay output framed pulse width. FIGURE 1.

... NOTE: The value chosen for the torque level set pot is dependent on the type of power MOSFET and motor characteristics. The TRIGGER is a combined SW/Speed Control function. Motor speed increases as the TRIGGER voltage decreases. Speed control range: 2.35V (Min) < V FIGURE 2.
