Description

The HCA10008 is a high frequency, medium voltage Full Bridge N-Channel FET driver IC, available in 20 lead plastic SOIC package. The HCA10008 can drive every possible switch combination except those which would cause a shoot through condition. The HCA10008 can switch at frequencies up to 1MHz and is well suited to driving Voice Coil Motors, high-frequency Class D audio amplifiers, and power supplies.

For example, the HCA10008 can drive medium voltage brush motors, and two HCA10008s can be used to drive high performance stepper motors, since the short minimum "on-time" can provide fine micro-stepping capability. 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.
