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.

DESCRIPTION
Gate driver supplies. One external bootstrap diode and one capacitor are required for each. The bootstrap diode
and capacitor may be omitted when the HIP4083 is used to drive the lower gates in three phase full bridge
applications. In this case, tie all three xHB pins to V
DD
and tie the xHS pins to the sources of the lower FETs. In
full bridge applications, the lower FETs must be turned on first at start up to refresh the bootstrap capacitors. In
high side switch applications, the load will keep xHS low and refresh should happen automatically at start up.
Logic level inputs. Logic at these three pins controls the three output drivers, AHO, BHO and CHO. When xHI is
low, xHO is high. When xHI is high, xHO is low. DIS (Disable) overrides all input signals. xHI can be driven by
signal levels of 0V to 15V (no greater than V
DD
).
Chip ground.
Undervoltage setting. A resistor can be connected between this pin and V
SS
to program the under voltage set
point - see Figure 7. With this pin not connected the undervoltage set point is typically 7V. When this pin is tied to
V
DD
, the undervoltage set point is typically 6.2V.
Disable input. Logic level input that when taken high sets all three outputs low. DIS high overrides all other inputs.
When DIS is taken low the outputs are controlled by the other inputs. DIS can be driven by signal levels of 0V to
15V (no greater than V
DD
).
Gate connections. Connect to the gates of the power MOSFETs in each phase.

MOSFET source connection. Connect the sources of the power MOSFETs and the negative side of the bootstrap
capacitors to these pins. In high side switch applications, 2mA of current will flow out of these pins into the load
when the upper FETs are off. This current is necessary to guarantee that the upper FETs stay off. This current
tends to pull xHS high. For proper refresh, the load must pull the voltage on xHS down to at least 7V below V
DD
.
For example, when V
DD
= 12V, xHS must be pulled down to 5V. Therefore, the minimum load necessary for
proper refresh is given by the following equation: R
MIN
= 5V/2mA = 2.5kΩ. So in this case, if the load has an
impedance less than 5kΩ, refresh will happen automatically at start up.
Positive supply rail. Bypass this pin to V
SS
with a capacitor
>1µF.
In applications where the bus voltage and chip
V
DD
are at the same potential, it is a good idea to run a separate line from the supply to each. This greatly
simplifies the filtering requirements.
