HCA10008

Data Sheet

August 1999

File Number

4772

80V/2.5A Peak, High Frequency Full

Bridge FET Driver

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 ampli鏗乪rs, 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

鈥渙n-time鈥?can provide 鏗乶e 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.
