DATASHEET ISL83204A FN6397 Rev.2.00 60V/2.5A Peak, High Frequency Full Bridge FET Driver March 20, 2007 The ISL83204A is a high frequency, medium voltage Full Features Bridge N-Channel FET driver IC, available in 20 lead plastic Drives N-Channel FET Full Bridge Including High Side SOIC and DIP packages. The ISL83204A includes an input Chop Capability comparator used to facilitate the hysteresis and PWM modes of operation. Its HEN (high enable) lead can force Bootstrap Supply Max Voltage to 75VDC current to freewheel in the bottom two external power Drives 1000pF Load at 1MHz in Free Air at +50C with MOSFETs, maintaining the upper power MOSFETs off. Rise and Fall Times of Typically 10ns Since it can switch at frequencies up to 1MHz, the User-Programmable Dead Time ISL83204A is well suited for driving Voice Coil Motors, switching power amplifiers and power supplies. Charge-Pump and Bootstrap Maintain Upper Bias Supplies ISL83204A can also drive medium voltage brush motors, and two ISL83204As can be used to drive high performance DIS (Disable) Pin Pulls Gates Low stepper motors, since the short minimum on-time can Input Logic Thresholds Compatible with 5V to 15V Logic provide fine micro-stepping capability. Levels Short propagation delays of approximately 55ns maximize Very Low Power Consumption control loop crossover frequencies and dead-times which Undervoltage Protection can be adjusted to near zero to minimize distortion, resulting in precise control of the driven load.
