HIP4080A  
80V/2.5A Peak, High Frequency  
Full Bridge FET Driver  
March 1995  
Features  
Description  
• 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,  
used to facilitate the “hysteresis” and PWM modes of operation.  
• Bootstrap Supply Max Voltage to 95VDC  
• Drives 1000pF Load at 1MHz in Free Air at +50oC with 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  
1MHz, the HIP4080A is well suited for driving Voice Coil  
• User-Programmable Dead Time  
• 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  
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.  
• 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 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  
The similar HIP4081A IC allows independent control of all 4  
FETs in an Full Bridge configuration.  
The Application Note for the HIP4080A is AN9404.
