HIP4086ABT

Full Half-Bridge (H Bridge) Drivers Overview

The HIP4086ABT is a three-phase N-channel MOSFET driver designed for PWM motor control applications. It features independently driven high-side and low-side outputs with a peak turn-off current of 1.25A. The device supports a bootstrap supply voltage up to 95VDC and operates with a bias supply between 7V and 15V. It includes user-programmable dead time ranging from 0.5µs to 4.5µs and programmable undervoltage lockout thresholds. The component utilizes a 20-lead SOIC package.

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the specific suffix 'BT' against official Renesas/Intersil documentation, as standard datasheets primarily reference the 'APZ' or 'ABZ' variants. Confirm lead-free status and RoHS compliance through the manufacturer's legacy product database. Ensure the source document explicitly defines the 'BT' designation to avoid functional mismatches during procurement.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component for low-frequency motor drive applications up to 100kHz. The integrated charge pumps support long on-times, distinguishing it from the HIP4086A variant which disables them for EMI reduction. Verify that the required dead time range and undervoltage set points align with the specific motor control requirements.

Full Half-Bridge (H Bridge) Drivers Part Context

This part belongs to the HIP4086 series of three-phase gate drivers manufactured by Intersil, now part of Renesas Electronics. The series is engineered for robust performance in motor control systems requiring precise timing and high-side driving capabilities. The HIP4086ABT represents a specific packaging or revision within this established family of analog power management ICs.

Full Half-Bridge (H Bridge) Drivers FAQ

What is the primary difference between the HIP4086 and HIP4086A?

The HIP4086 includes built-in charge pumps to allow indefinitely long on-times for high-side drivers, whereas the HIP4086A has these charge pumps disabled to reduce EMI noise.

Can the shoot-through protection be disabled?

Yes, the device allows users to override the shoot-through protection, which is specifically useful for switched reluctance motor applications.
