HIP4080A
March 1995
80V/2.5A Peak, High Frequency
Full Bridge FET Driver
Description
Features
• Drives N-Channel FET Full Bridge Including High Side
The HIP4080A is a high frequency, medium voltage Full Bridge
Chop Capability
N-Channel FET driver IC, available in 20 lead plastic SOIC and
DIP packages. The HIP4080A includes an input comparator,
• Bootstrap Supply Max Voltage to 95VDC
used to facilitate the “hysteresis” and PWM modes of operation.
o
C with
• Drives 1000pF Load at 1MHz in Free Air at +50
Its HEN (high enable) lead can force current to freewheel in the
Rise and Fall Times of Typically 10ns
bottom two external power MOSFETs, maintaining the upper
power MOSFETs off. Since it can switch at frequencies up to
• User-Programmable Dead Time
1MHz, the HIP4080A is well suited for driving Voice Coil
• Charge-Pump and Bootstrap Maintain Upper Bias
Motors, switching amplifiers in class D high-frequency switching
Supplies
audio amplifiers and power supplies.
• DIS (Disable) Pin Pulls Gates Low
• Input Logic Thresholds Compatible with 5V to 15V
Logic Levels
• Very Low Power Consumption
• Undervoltage Protection
HIP4080A can also drive medium voltage brush motors, and
two HIP4080As can be used to drive high performance step-
per 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 precise control of the driven load.
The similar HIP4081A IC allows independent control of all 4
FETs in an Full Bridge configuration.
The Application Note for the HIP4080A is AN9404.
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
• U.P.S.
