DATASHEET

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

• 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)

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 and optional charge pump maintain the high-side

driver bias voltage.

• Programmable bootstrap refresh time

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.

• Drives 1000pF load with typical rise time of 20ns and fall

time of 10ns

• Programmable undervoltage set point

Applications

• Brushless Motors (BLDC)

• 3-phase AC motors

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.

• Switched reluctance motor drives

• Battery powered vehicles

• Battery powered tools

Another useful feature of the HIP4086/A is the programmable

undervoltage set point. The set point range varies from 6.6V to

8.5V.
