Description
The HIP4083 is a three phase high side N-channel MOSFET
driver, specifically targeted for PWM motor control. Two
HIP4083 may be used together for 3 phase full bridge appli-
cations (see application block diagram). Alternatively, the
lower gates may be controlled directly from a buffered micro-
processor output.
Unlike other members of the HIP408x family, the HIP4083
has no built in turn-on delay. Each output (AHO, BHO, and
CHO) will turn-on 65ns after its input is switched low. Like-
wise, each output will turn-off 60ns after its input is switched
high. Very short and very long dead times are possible when
two HIP4083 are used to drive a full bridge. This dead time is
controlled by the input signal timing.
The HIP4083 does not have a built in charge pump. There-
fore, the bootstrap capacitors must be recharged on a peri-
odic basis by initiating a short refresh pulse. In most bridge
applications, this will happen automatically every time the
lower FETs turn-on and the upper FETs turn-off. However, it
is still possible to use the HIP4083 in applications that
require the high side FETs to be on for extended periods of
time. This can be easily accomplished by sending a short
refresh pulse to the DIS pin.
The HIP4083 has reduced drive current compared to the
HIP4086 making it ideal for low to moderate power applica-
tions. The HIP4083 is optimized for applications where size
and cost are important. For high power applications driving
large power FETs, the HIP4086 is recommended.
