HIP4081A Data Sheet September 15, 2015 FN3659.8 80V/2.5A Peak, High Frequency Full Features Bridge FET Driver Independently Drives 4 N-Channel FET in Half Bridge or The HIP4081A is a high frequency, medium voltage Full Full Bridge Configurations Bridge N-Channel FET driver IC, available in 20 lead plastic Bootstrap Supply Max Voltage to 95V DC SOIC and DIP packages. The HIP4081A can drive every Drives 1000pF Load at 1MHz in Free Air at 50C with Rise possible switch combination except those which would and Fall Times of Typically 10ns cause a shoot-through condition. The HIP4081A can switch at frequencies up to 1MHz and is well suited to driving Voice User-Programmable Dead Time Coil Motors, high-frequency switching power amplifiers, and On-Chip Charge-Pump and Bootstrap Upper Bias power supplies. Supplies For example, the HIP4081A can drive medium voltage brush DIS (Disable) Overrides Input Control motors, and two HIP4081As can be used to drive high Input Logic Thresholds Compatible with 5V to 15V Logic performance stepper motors, since the short minimum Levels on-time can provide fine micro-stepping capability. Very Low Power Consumption Short propagation delays of approximately 55ns maximizes control loop crossover frequencies and dead-times which Undervoltage Protection can be adjusted to near zero to minimize distortion, resulting Pb-free Available in rapid, precise control of the driven load. Applications A similar part, the HIP4080A, includes an on-chip input comparator to create a PWM signal from an external triangle Medium/Large Voice Coil Motors wave and to facilitate hysteresis mode switching. Full Bridge Power Supplies The Application Note for the HIP4081A is the AN9405.
