HIP4080  
80V/2.5A Peak, High Frequency  
Full Bridge FET Driver  
December 1996  
Features  
Description  
• Drives N-Channel FET Full Bridge Including High Side The HIP4080 is a high frequency, medium voltage Full Bridge  
N-Channel FET driver IC, available in 20 lead plastic SOIC and  
DIP packages. The HIP4080 includes an input comparator,  
used to facilitate the “hysteresis” and PWM modes of operation.  
Its HEN (high enable) lead can force current to freewheel in the  
bottom two external power MOSFETs, maintaining the upper  
power MOSFETs off. Since it can switch at frequencies up to  
1MHz, the HIP4080 is well suited for driving Voice Coil Motors,  
switching amplifiers in class D high-frequency switching audio  
amplifiers and power supplies.  
Chop Capability  
• 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 10ns (Typ)  
• User-Programmable Dead Time  
• Charge-Pump and Bootstrap Maintain Upper Bias  
Supplies  
HIP4080 can also drive medium voltage brush motors, and  
two HIP4080s can be used to drive high performance step-  
per motors, since the short minimum “on-time” can provide  
fine micro-stepping capability.  
• DIS (Disable) Pin Pulls Gates Low  
• Input Logic Thresholds Compatible with 5V to 15V  
Logic Levels  
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.  
• Very Low Power Consumption  
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 HIP4081 IC allows independent control of all 4  
FETs in an Full Bridge configuration.  
See also, Application Note AN9324 for the HIP4080.  
Similar part, HIP4080A, includes under voltage circuitry  
which doesn’t require the circuitry shown in Figure 30 of this  
data sheet.
