80V, 500mA, 3-Phase MOSFET Driver
The HIP4086 and HIP4086A (referred to as the HIP4086/A)
are 3-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.
Features
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.
• 1.25A peak turn-off current
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.
• Independently drives 6 N-channel MOSFETs in 3-phase
bridge configuration
• Bootstrap supply maximum voltage up to 95VDC with bias
supply from 7V to 15V
• User programmable dead time (0.5µs to 4.5µs)
• Bootstrap and optional charge pump maintain the high-side
driver bias voltage.
• Programmable bootstrap refresh time
• Drives 1000pF load with typical rise time of 20ns and fall
time of 10ns
• Programmable undervoltage set point
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.
Applications
Another useful feature of the HIP4086/A is the programmable
undervoltage set point. The set point range varies from 6.6V to
8.5V.
