DATASHEET HIP4081A FN3659 Rev 8.00 80V/2.5A Peak, High Frequency Full Bridge FET Driver September 15, 2015 The HIP4081A is a high frequency, medium voltage Full Features Bridge N-Channel FET driver IC, available in 20 lead plastic Independently Drives 4 N-Channel FET in Half Bridge or SOIC and DIP packages. The HIP4081A can drive every Full Bridge Configurations possible switch combination except those which would cause a shoot-through condition. The HIP4081A can switch Bootstrap Supply Max Voltage to 95V DC at frequencies up to 1MHz and is well suited to driving Voice Drives 1000pF Load at 1MHz in Free Air at 50C with Rise Coil Motors, high-frequency switching power amplifiers, and and Fall Times of Typically 10ns power supplies. User-Programmable Dead Time For example, the HIP4081A can drive medium voltage brush On-Chip Charge-Pump and Bootstrap Upper Bias motors, and two HIP4081As can be used to drive high Supplies performance stepper motors, since the short minimum on-time can provide fine micro-stepping capability. DIS (Disable) Overrides Input Control Input Logic Thresholds Compatible with 5V to 15V Logic Short propagation delays of approximately 55ns maximizes Levels control loop crossover frequencies and dead-times which can be adjusted to near zero to minimize distortion, resulting Very Low Power Consumption in rapid, precise control of the driven load. Undervoltage Protection A similar part, the HIP4080A, includes an on-chip input Pb-free Available comparator to create a PWM signal from an external triangle wave and to facilitate hysteresis mode switching.
