HCA10008
Data Sheet
August 1999
File Number 4772
80V/2.5A Peak, High Frequency Full
Bridge FET Driver
Features
• Independently Drives 4 N-Channel FET in Half Bridge or
Full Bridge Configurations
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.
• Bootstrap Supply Max Voltage to 95V
DC
o
• Drives 1000pF Load at 1MHz in Free Air at 50 C with Rise
and Fall Times of Typically 10ns
• User Programmable Dead Time
• On-Chip Charge Pump and Bootstrap Upper Bias
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.
• DIS (Disable) Overrides Input Control
• Input Logic Thresholds Compatible with 5V to 15V Logic
Levels
• Very Low Power Consumption
• Undervoltage Protection
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.
Applications
• Medium/Large Voice Coil Motors
• Full Bridge Power Supplies
• Class D Audio Power Amplifiers
• High Performance Motor Controls
• Noise Cancellation Systems
• Battery Powered Vehicles
• Peripherals
