HIP4086

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 (0.25

µs 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.
