80V/2.5A Peak, High Frequency 100 Bridge FET Driver The HCA10008 is a high frequency, medium voltage full bridge N-channel FET driver IC, available in a 20 lead plastic SOIC package. The HCA10008 can drive every possible switch combination except those that would cause shooting through conditions. The HCA10008 can switch frequencies up to 1MHz and is ideal for driving voice coil motors, high frequency Class D audio amplifiers and power supplies. For example, a medium voltage HCA10008 brush motor can be driven, and two HCA10008s can be used to drive a high-performance stepper motor, as the short-term minimum "on-time" can provide fine microstepping capabilities. The short propagation delay of about 55ns maximizes the control loop crossover frequency and dead times, which can be adjusted to near zero to minimize distortion, resulting in fast, precisely controlled drive loads.
