80V, 0.5A Three Phase Driver
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 (0.25µs to 4.5µs) - 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.
