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
• 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
• 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.
• Programmable bootstrap refresh time
• 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
• Switched reluctance motor drives
• Battery powered vehicles
• Battery powered tools
