Portable Battery Drive/torque Controller For N-channel Mosfets In Motor Control Systems Corporation

The HIP9021IB is a dedicated Power MOSFET driver which drives a DC motor. As a 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. As the TRIGGER voltage level is decreased the duty-cycle of the square wave and the speed of the motor is increased. The torque of the motor is limited by the voltage level sensed at the drain of the external Power MOSFET When the cur- rent reaches an adjustable limit set at the TORQUE input, the drive of the Power MOSFET is disabled. The system control components include 2 adjustable poten- tiometer controls and 2 capacitors for the operating fre- quency and torque delay control. A xed or battery supply voltage in the range of 5V to 15V may be used. The HIP9021IB is provided in a small outline plastic package for a compact surface mount to a ceramic substrate. The surface mount assembly CAN be t directly into the trigger of a portable electric drill. By Intersil Corporation
