High Frequency Full Bridge FET Driver

® ISL83204A Data Sheet March 20, 2007 FN6397.2 60V/2.5A Peak, High Frequency Full Bridge FET Driver The ISL83204A is a high frequency, medium voltage Full Bridge N-Channel FET driver IC, available in 20 lead plastic SOIC and DIP packages. The ISL83204A includes an input comparator used to facilitate the “hysteresis” and PWM modes of operation. Its HEN (high enable) lead can force current to freewheel in the bottom two external power MOSFETs, maintaining the upper power MOSFETs off. Since it can switch at frequencies up to 1MHz, the ISL83204A is well suited for driving Voice Coil Motors, switching power amplifiers and power supplies. ISL83204A can also drive medium voltage brush motors, and two ISL83204As can be used to drive high performance stepper motors, since the short minimum “on-time” can provide fine micro-stepping capability. Short propagation delays of approximately 55ns maximize control loop crossover frequencies and dead-times which can be adjusted to near zero to minimize distortion, resulting in precise control of the driven load.
