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 applications (see application block diagram). Alternatively, the
lower gates may be controlled directly from a b uffered microprocessor 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. Likewise, each output will turn-off 60ns after its input is switched
high. V ery 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. Therefore, the bootstrap capacitors must be recharged on a periodic 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 applications. The HIP4083 is optimized for applications where size
and cost are important. For high power applications driving
large power FETs, the HIP4086 is recommended.
