80V, 500mA, 3-Phase MOSFET Driver
HIP4086, HIP4086A
Features
The HIP4086 and HIP4086A (referred to as the HIP4086/A)
are three phase N-Channel MOSFET drivers. Both parts are
specifically targeted for PWM motor control. These drivers
have flexible input protocol for driving every possible switch
combination. The user can even override the shoot-through
protection for switched reluctance applications.
• Independently drives 6 N-Channel MOSFETs in three-phase
bridge configuration
The HIP4086/A have a wide range of programmable dead
times (0.5µs to 4.5µs) which makes them very suitable for the
low frequencies (up to 100kHz) typically used for motor drives.
• Bootstrap supply max voltage up to 95VDC with bias supply
from 7V to 15V
• 1.25A peak turn-off current
• User programmable dead time (0.5µs to 4.5µs)
• Bootstrap and optional charge pump maintain the high-side
driver bias voltage.
The only difference between the HIP4086 and the HIP4086A
is that the HIP4086A has the built-in charge pumps disabled.
This is useful in applications that require very quiet EMI
performance (the charge pumps operate at 10MHz). The
advantage of the HIP4086 is that the built-in charge pumps
allow indefinitely long on times for the high-side drivers.
• Programmable bootstrap refresh time
To insure that the high-side driver boot capacitors are fully
charged prior to turning on, a programmable bootstrap refresh
pulse is activated when VDD is first applied. When active, the
refresh pulse turns on all three of the low-side bridge FETs
while holding off the three high-side bridge FETs to charge the
high-side boot capacitors. After the refresh pulse clears,
normal operation begins.
• Brushless Motors (BLDC)
Another useful feature of the HIP4086/A is the programmable
undervoltage set point. The set point range varies from 6.6V to
8.5V.
• Drives 1000pF load with typical rise time of 20ns and fall
time of 10ns
• Programmable undervoltage set point
Applications
• 3-phase AC motors
• Switched reluctance motor drives
• Battery powered vehicles
• Battery powered tools

(xHI)
High-Side Logic Level Inputs. Logic at these three pins controls the three high-side output
drivers, AHO (Pin 17), BHO (Pin 24) and CHO (Pin 14). When xHI is low, xHO is high. When xHI
is high, xHO is low. Unless the dead time is disabled by connecting RDEL (Pin 7) to ground, the
low-side input of each phase will override the corresponding high side input on that phase see “Truth Table” on page 2. If RDEL is tied to ground, dead time is disabled and the outputs
follow the inputs with no shoot-thru protection. DIS (Pin 10) also overrides the high-side inputs.
xHI can be driven by signal levels of 0V to 15V (no greater than VDD).

ALI
BLI
CLI
(xLI)
Low-Side Logic Level Inputs. Logic at these three pins controls the three low-side output
drivers ALO (Pin 21), BLO (Pin 22) and CLO (Pin 19). If the upper inputs are grounded then the
lower inputs control both xLO and xHO drivers, with the dead time set by the resistor at RDEL
(Pin 7). DIS (Pin 10) high level input overrides xLI, forcing all outputs low. xLI can be driven by
signal levels of 0V to 15V (no greater than VDD).
6
VSS
Ground. Connect the sources of the low-side power MOSFETs to this pin.
7
RDEL
Delay Time Set Point. Connect a resistor from this pin to VDD to set timing current that defines
the dead time between drivers - see Figure 18. All drivers turn off with minimal delay, RDEL
resistor prevents shoot-through by delaying the turn-on of all drivers. When RDEL is tied to VSS,
both upper and lowers can be commanded on simultaneously. While not necessary in most
applications, a decoupling capacitor of 0.1µF or smaller may be connected between RDEL and
VSS.
8
UVLO
Undervoltage Set Point. A resistor can be connected between this pin and VSS to program the
undervoltage set point - see Figure 19. With this pin not connected, the under voltage disable
is typically 6.6V. When this pin is tied to VDD , the under voltage disable is typically 6.2V.
9
RFSH
Refresh Pulse Setting. An external capacitor can be connected from this pin to VSS to increase
the length of the start up refresh pulse - see Figure 17. If this pin is not connected, the refresh
pulse is typically 1.5µs.
10
DIS
Disable Input. Logic level input that when taken high sets all six outputs low. DIS high
overrides all other inputs. With DIS low, the outputs are controlled by the other inputs. DIS can
be driven by signal levels of 0V to 15V (no greater than VDD).

Functional Description
Input Logic
NOTE: When appropriate for brevity, input and output pins will be prefixed
with an “x” as a substitute for A, B, or C. For example, xHS refers to pins
AHS, BHS, and CHS.
The HIP4086/A is a three phase bridge driver designed
specifically for motor drive applications. Three identical half
bridge sections, A, B, and C, can be controlled individually by
their input pins, ALI, AHI, BLI, BHI, and CLI, CHI (xLI, xHI) or the 2
corresponding input pins for each section can be tied together to
form a PWM input (xLI connected to xHI = xPWM). When
controlling individual inputs, the programmable dead time is
optional but shoot-thru protection must then be incorporated in
the timing of the input signals. If the PWM mode is chosen, then
the internal programmable dead time must be used.
Shoot-Thru Protection
Dead time, to prevent shoot-thru, is implemented by delaying the
turn-on of the high-side and low-side drivers. The delay timers are
Submit Document Feedback
10
enabled if the voltage on the RDEL pin is greater than 100mV.
The voltage on RDEL will be greater than 100mV for any value of
programming resistor in the specified range. If the voltage on
RDEL is less than 100mV, the delay timers are disabled and no
shoot-thru protection is provided by the internal logic of the
HIP4086/A. When the dead time is to be disabled, RDEL should
be shorted to VSS.
Refresh Pulse
To insure that the boot capacitors are charged prior to turning on
the high-side drivers, a refresh pulse is triggered when DIS is low
or when the UV comparator transitions low (VDD is greater than
the programmed undervoltage threshold). Please refer to the
“Block Diagram (for clarity, only one phase is shown)” on page 2.
When triggered, the refresh pulse turns on all of the low-side
drivers (xLO = 1) and turns off all of the high-side drivers
(xHO = 0) for a duration set by a resistor tied between RDEL and
VSS. When xLO = 1, the low-side bridge FETs charge the boot
caps from VDD through the boot diodes.
FN4220.10
March 27, 2015
HIP4086, HIP4086A
Charge Pump
The internal charge pump of the HIP4086/A is used to maintain
the bias on the boot cap for 100% duty cycle. There is no limit for
the duration of this period. The user must understand that this
charge pump is only intended to provide the static bias current of
the high-side drivers and the gate leakage current of the
high-side bridge FETs. It cannot provide in a reasonable time, the
majority of the charge on the boot cap that is consumed, when
the xHO drivers source the gate charge to turn on the high-side
bridge FETs. The boot caps should be sized so that they do not
discharge excessively when sourcing the gate charge. See
“Application Information” on page 11 for methods to size the
boot caps.
The charge pump has sufficient capacity to source a worst-case
minimum of 50µA to the external load. The gate leakage current
of most power MOSFETs is about 100nA so there is more than
sufficient current to maintain the charge on the boot caps.
Because the charge pump current is small, a gate-source resistor
on the high-side bridge FETs is not recommended. When
calculating the leakage load on the outputs of xHS, also include
the leakage current of the boot capacitor. This is rarely a problem
but it could be an issue with electrolytic capacitors at high
temperatures.
Application Information
Equation 1 calculates the total charge required for the Period
duration. This equation assumes that all of the parameters are
constant during the Period duration. The error is insignificant if
Ripple is small.
Q C = Q gate80V + Period  (I HB + V HO  R GS + I gate_leak )
C boot = Q C   Ripple VDD 
(EQ. 1)
C boot = 0.52F
If the gate to source resistor is removed (RGS is usually not
needed or recommended), then:
Cboot = 0.33µF
These values of Cboot will sustain the high side driver bias during
Period with only a small amount of Ripple. But in the case of the
HIP4086, the charge pump reduces the value of Cboot even
more. The specified charge pump current is a minimum of 50µA
which is more than sufficient to source Igate_leak. Also, because
the specified charge pump current is in excess of what is needed
for IHB, the total charge required to be sourced by the boot
capacitor is shown by Equation 2.
(EQ. 2)
Q C = Q gate80V or Cboot = 0.13F
Not only is the required boot cap smaller in value, there is no
restriction on the duration of Period.
Selecting the Boot Capacitor Value
The boot capacitor value is chosen not only to supply the internal
bias current of the high-side driver but also, and more
significantly, to provide the gate charge of the driven FET without
causing the boot voltage to sag excessively. In practice, the boot
capacitor should have a total charge that is about 20 times the
gate charge of the driven power FET for approximately a 5% drop
in voltage after charge has been transferred from the boot
capacitor to the gate capacitance.
The following parameters shown in Table 1 are required to
calculate the value of the boot capacitor for a specific amount of
voltage droop when using the HIP4086/A (no charge pump). In
Table 1, the values used are arbitrary. They should be changed to
comply with the actual application.

FIGURE 22. TYPICAL APPLICATION CIRCUIT
Figure 22 is an example of how the HIP4086 and HIP4086A
3-phase drivers can be applied to drive a 3-phase motor.
Depending on the application, the switching speed of the bridge
FETs can be reduced by adding series connected resistors
between the xHO outputs and the FET gates. Gate-Source
resistors are recommended on the low-side FETs to prevent
unexpected turn-on of the bridge should the bridge voltage be
applied before VDD. Gate-to-source resistors on the high-side
FETs are not usually required if low-side gate-to-source resistors
are used. If relatively small gate-to-source resistors are used on
the high-side FETs, be aware that they will load the charge pump
of the HIP4086 negating the ability of the charge pump to keep
the high-side driver biased during very long periods.
An important operating condition that is frequently overlooked by
designers is the negative transient on the xHS pins that occurs
when the high-side bridge FET turns off. The Absolute Maximum
transient allowed on the xHS pin is -6V but it is wise to minimize
the amplitude to lower levels. This transient is the result of the
parasitic inductance of the low-side drain-to-source conductor on
the PCB. Even the parasitic inductance of the low-side FET
contributes to this transient.

FIGURE 23. BRIDGE WITH PARASITIC INDUCTANCES

When the high-side bridge FET turns off, because of the inductive
characteristics of a motor load, the current that was flowing in
the high-side FET (blue) must rapidly commutate to flow through
the low-side FET (red). The amplitude of the negative transient
impressed on the xHS node is (di/dt x L) where L is the total
parasitic inductance of the low-side FET drain-source path and
di/ddt is the rate at which the high-side FET is turned off. With
the increasing power levels of new generation motor drives,
clamping this transient becomes more and more significant for
the proper operation of the HIP4086/A.
There are several ways of reducing the amplitude of this
transient. If the bridge FETs are turned off more slowly to reduce
di/dt, the amplitude will be reduced but at the expense of more
switching losses in the FETs. Careful PCB design will also reduce
the value of the parasitic inductance. However, these two
solutions by themselves may not be sufficient. Figure 23
illustrates a simple method for clamping the negative transient.
Two series connected, fast PN junction, 1A diodes are connected
between xHS and VSS as shown. It is important that the
components be placed as close as possible to the xHS and VSS
pins to minimize the parasitic inductance of this current path.
Two series connected diodes are required because they are in
parallel with the body diode of the low-side FET. If only one diode
is used for the clamp, it will conduct some of the negative load
current that is flowing in the low-side FET. In severe cases, a
small value resistor in series with the xHS pin as shown, will
further reduce the amplitude of the negative transient.
Please note that a similar transient with a positive polarity occurs
when the low-side FET turns off. This is less frequently a problem
because xHS node is floating up toward the bridge bias voltage.
The Absolute Max voltage rating for the xHS node does need to
be observed when the positive transient occurs.

HIP4086, HIP4086A
General PCB Layout Guidelines
The AC performance of the HIP4086/A depends significantly on
the design of the PC board. The following layout design
guidelines are recommended to achieve optimum performance:
• Place the driver as close as possible to the driven power FETs.
• Understand where the switching power currents flow. The high
amplitude di/dt currents of the driven power FET will induce
significant voltage transients on the associated traces.
• Keep power loops as short as possible by paralleling the
source and return traces.
• Use planes where practical; they are usually more effective
than parallel traces.
• Avoid paralleling high amplitude di/dt traces with low level
signal lines. High di/dt will induce currents and consequently,
noise voltages in the low level signal lines.
• When practical, minimize impedances in low level signal
circuits. The noise, magnetically induced on a 10kΩ resistor, is
10x larger than the noise on a 1kΩ resistor.
• Be aware of magnetic fields emanating from motors,
transformers and inductors. Gaps in these magnetic structures
are especially bad for emitting flux.
• It may be necessary to add resistance to dampen resonating
parasitic circuits especially on xHO and xLO. If an external gate
resistor is unacceptable, then the layout must be improved to
minimize lead inductance.
• Keep high dv/dt nodes away from low level circuits. Guard
banding can be used to shunt away dv/dt injected currents
from sensitive circuits. This is especially true for control circuits
that source the input signals to the HIP4086/A.
• Avoid having a signal ground plane under a high amplitude
dv/dt circuit. This will inject di/dt currents into the signal
ground paths.
• Do power dissipation and voltage drop calculations of the
power traces. Many PCB/CAD programs have built in tools for
calculation of trace resistance.
• Large power components (Power FETs, Electrolytic caps, power
resistors, etc.) will have internal parasitic inductance which
cannot be eliminated. This must be accounted for in the PCB
layout and circuit design.
• If you simulate your circuits, consider including parasitic
components especially parasitic lead inductance.
• If you must have traces close to magnetic devices, align the
traces so that they are parallel to the flux lines to minimize
coupling.
• The use of low inductance components such as chip resistors
and chip capacitors is highly recommended.
• Use decoupling capacitors to reduce the influence of parasitic
inductance in the VDD and GND leads. To be effective, these
caps must also have the shortest possible conduction paths. If
vias are used, connect several paralleled vias to reduce the
inductance of the vias.
