HIP4083
80V, 300mA Three Phase High Side Driver
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 buffered
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. 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.
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.

NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which is compatible with both SnPb and
Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J Std-020B.
