HIP4080AIPZ 80V/2.5A Peak, High Frequency Full Bridge FET Driver
80V/2.5A Peak, High Frequency Full Bridge
FET Driver
The HIP4080A is a high frequency, medium voltage Full
Bridge 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. 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 HIP4080A
is well suited for driving Voice Coil Motors, switching power
amplifiers and power supplies.
HIP4080A can also drive medium voltage brush motors, and
two HIP4080As can be used to drive high performance
stepper motors, since the short minimum “on-time” can
provide fine micro-stepping capability.
Short propagation delays of approximately 55ns maximize
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 a Full Bridge configuration.
The Application Note for the HIP4080A is AN9404
