HIP4086ABZT

Full Half-Bridge (H Bridge) Drivers Overview

The HIP4086ABZT is a three-phase N-channel MOSFET driver integrated circuit designed for PWM motor control applications. It features six independent drivers configured for a three-phase bridge topology, operating with a bias supply voltage range of 7V to 15V and a maximum bootstrap voltage of 95VDC. The device provides a peak output current of 500mA and supports programmable dead times ranging from 0.5μs to 4.5μs. It includes built-in charge pumps for indefinite high-side on-times and offers a programmable undervoltage lockout set point between 6.6V and 8.5V. The component is housed in a 24-pin SOIC package.

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the specific suffix 'ABZT' against the manufacturer's datasheet to confirm tape-and-reel packaging and temperature grade. Ensure the application requires the active charge pump version rather than the EMI-optimized HIP4086A variant. Cross-reference pinouts and electrical characteristics with official Renesas documentation prior to integration.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component when designing three-phase motor controllers requiring independent high-side and low-side drive capabilities. The built-in charge pumps are essential for applications demanding long duty cycles without frequent refresh pulses. Consider the HIP4086A variant if electromagnetic interference reduction is prioritized over continuous high-side conduction capability.

Full Half-Bridge (H Bridge) Drivers Part Context

The HIP4086 series belongs to Renesas' specialized gate driver family targeting industrial motor control. This specific part integrates logic inputs, dead-time generation, and bootstrap management into a single package. It simplifies the design of complex power stages by handling timing constraints and level shifting internally.
