The HIP4081AIBZ is a high frequency, medium voltage Full-bridge N-channel FET Driver IC. It can drive every possible switch combination except those which would cause a shoot-through condition. This can switch at frequencies up to 1MHz and is well suited to driving voice coil motors, high-frequency switching power amplifiers and power supplies and can drive medium voltage brush motors. Short propagation delays of approximately 55ns maximizes control loop crossover frequencies and dead-times which can be adjusted to near zero to minimize distortion, resulting in rapid, precise control of the driven load.
- Independently drives 4 N-channel FET in full-bridge configurations
- 95VDC Bootstrap supply maximum voltage
- Drives 1000pF load at 1MHz in free air at 50°C
- User-programmable dead time
- On-chip Charge-pump and bootstrap upper bias supplies
- DIS (disable) overrides input control
- Very low power consumption
- Under voltage protection
