GR8853 - Self-oscillating Half-bridge Driver

General Description

GR8853 is a high voltage, high speed, self-oscillating power MOSFET and IGBT driver with both high and low side referenced output channels.

Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction.

Key Features

  • Floating channel designed for bootstrap operation to +600V.
  • Noise immunity of transient voltage.
  • Under-voltage lockout.
  • Programmable oscillator frequency.
  • Matched propagation delay for both channels.
  • Ultra low startup current of 75uA.
  • Shutdown function turns off both channels.
  • Low side output in phase with RT.
