Drive Solution for Heating or Inductive Coils

Renesas’ winning combination drive solution for heating or inductive coils improves efficiency and load control in external elements

Image of Renesas' Drive Solution for Heating or Inductive CoilsRenesas’ winning combination drive solution drives an external element, whether a coil for heating, a wire for generating a magnetic field, or an 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 its charge. A comparator and amplifiers are used to monitor current flow and trigger any overcurrent events.
