HIP4086AB

Full Half-Bridge (H Bridge) Drivers Overview

The HIP4086AB is a three-phase N-channel MOSFET driver designed for PWM motor control applications. It features six drivers in a 24-pin SOIC package with a supply voltage range of 7V to 15V and output current capability of 500mA. The device includes programmable dead time from 0.5μs to 4.5μs, built-in charge pumps operating at 10MHz, and a bootstrap refresh pulse for high-side capacitor charging. Operating temperature ranges from -40°C to +125°C.

• Battery powered vehicles
• Battery powered tools

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the specific suffix 'ABZ' against the requested model 'HIP4086AB' as datasheets primarily reference HIP4086A or HIP4086. Confirm RoHS compliance status and moisture sensitivity level requirements before procurement. Ensure the selected variant matches the requirement for disabled or enabled charge pumps, as the 'A' suffix typically indicates disabled charge pumps for EMI-sensitive designs.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select the HIP4086 variant if indefinite high-side on times are required due to active built-in charge pumps. Choose the HIP4086A variant for applications demanding very quiet EMI performance where charge pump operation at 10MHz is undesirable. Consider the programmable dead time range suitable for motor drive frequencies up to 100kHz when evaluating switching speed requirements.

Full Half-Bridge (H Bridge) Drivers Part Context

The HIP4086/A series belongs to Renesas Intersil's portfolio of specialized gate drivers for motor control. These components are engineered specifically for three-phase N-channel MOSFET configurations. The family distinguishes between standard models with active charge pumps and 'A' variants with disabled pumps to address different electromagnetic interference constraints in industrial and automotive environments.
