The HIP4086 is a Three Phase Bridge N-Channel MOSFET driver IC. The HIP4086 is specifically targeted for PWM motor control. It makes bridge based designs simple and flexible. Like the HIP4081, the HIP4086 has a flexible input protocol for driving every possible switch combination. Unlike the HIP4081, the user can override the shoot-through protection for switched reluctance applications. The HIP4086 has reduced drive current compared to the HIP4081 (0.5A vs 2.5A) and a much wider range of programmable dead times (0.25s to 4.5s) - like the HIP4082. The HIP4086 is suitable for applications requiring DC to 100kHz. Unlike the previous family members, the HIP4086 has a programmable undervoltage set point. Also refer to the HIP4083, three phase upper only MOSFET driver, for a lower current solution optimized for smaller motors.
