This solution drives an external element whether it be a coil for heating, a wire for generating a magnetic field, or inductor to propel a motor. A microcontroller (MCU) sends a pulse width modulated signal to the gate driver that efficiently connects power to the driving element or removes the charge from it. A comparator and amplifiers are used to monitor current flow and trigger any overcurrent events.

System Benefits​:

  • Improved drive efficiency
  • Improved load drive control
  • Achieves high bandwidth current measurement
  • Fast (1µs) overcurrent safety detection

Target Applications:

  • Heating elements
  • Driving motors
  • Discrete DC/DC converters
  • Perimeter fencing
