HIP4081AIPZ Datasheet PDF - Intersil

The HIP4081AIPZ 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

●Stresses those listed in absolute maximum ratings may cause permanent damage to the device.
