Product details
Overview
HIP4086AABZT from Renesas Electronics (formerly Intersil) is a 3-phase N-channel MOSFET gate driver IC designed for PWM-controlled brushless DC and AC motor drives. It delivers 1.25A peak turn-off current, supports 80V high-side operation with bootstrap bias up to 95V, and features user-programmable dead time from 0.5µs to 4.5µs - enabling robust shoot-through protection in battery-powered tools and vehicle traction inverters.
For engineers reviewing the HIP4086AABZT datasheet, HIP4086AABZT pinout, HIP4086AABZT application, or HIP4086AABZT equivalent, key selection considerations include its charge-pump-disabled architecture (vs. HIP4086), programmable undervoltage lockout (6.6–8.5V), bootstrap refresh pulse control, and 24-pin SOIC RoHS-compliant package with thermal resistance θJA = 51°C/W.
Technical Context
The HIP4086AABZT implements independent three-phase half-bridge drive logic with separate high-side (xHI/xHO) and low-side (xLI/xLO) inputs per phase, supporting both individual phase control and unified PWM modes. Its internal dead-time generator uses an external RDEL resistor to set delay timing, and its disable (DIS) and undervoltage (UVLO) inputs provide system-level fault response.
Unlike the HIP4086, the HIP4086AABZT permanently disables the internal 10MHz charge pump - eliminating EMI noise sources while requiring external bootstrap capacitor sizing to sustain high-side bias during 100% duty cycle operation. The bootstrap refresh pulse (configurable via RFSH capacitor) ensures boot capacitor precharge before startup by simultaneously activating all low-side outputs.

Pinout & Package
HIP4086AABZT is housed in a 24-lead SOIC package (M24.3) with exposed pad thermal enhancement. Pin functions are fully defined across all three phases (A/B/C) using x-prefix notation (e.g., xHI = AHI/BHI/CHI).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AHI, BHI, CHI (Pins 5, 2, 12) | High-side logic inputs | Invert logic: low input → high output (xHO); overrides xLI when dead time enabled |
| ALI, BLI, CLI (Pins 4, 3, 11) | Low-side logic inputs | Direct drive: high input → high output (xLO); disabled when DIS = high |
| AHO, BHO, CHO (Pins 17, 24, 14) | High-side gate drivers | Drive gates of high-side N-MOSFETs; referenced to floating xHS nodes |
| ALO, BLO, CLO (Pins 21, 22, 19) | Low-side gate drivers | Drive gates of low-side N-MOSFETs; referenced to VSS ground |
| AHS, BHS, CHS (Pins 18, 23, 15) | High-side source connections | Connect to sources of high-side power FETs and negative terminals of bootstrap capacitors |
| AHB, BHB, CHB (Pins 16, 1, 13) | High-side bias connections | Connect cathode of bootstrap diode and positive terminal of bootstrap capacitor per phase |
| RDEL (Pin 7) | Dead time programming | Resistor-to-VDD sets dead time; <100mV disables dead time and shoot-through protection |
| RFSH (Pin 9) | Bootstrap refresh timing | Capacitor-to-VSS extends startup refresh pulse duration (typ. 1.5µs unconnected) |
| UVLO (Pin 8) | Undervoltage threshold adjust | Resistor-to-VSS programs disable threshold between 6.6V and 8.5V |
| DIS (Pin 10) | Global disable input | Logic-high forces all six outputs low; overrides all other inputs including UVLO |
| VDD (Pin 20) | Positive supply | 7–15V operation; powers logic, level shifters, and drivers; requires local decoupling |
| VSS (Pin 6) | Ground reference | Common return for low-side FET sources and logic ground; must be low-impedance |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-phase N-channel gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HIP4086ABZT | Includes functional 10MHz charge pump; enables indefinite high-side on-time without external capacitor recharge | Better suited for continuous-duty industrial drives where 100% duty cycle is common | Select HIP4086ABZT if charge pump functionality is required; HIP4086AABZT is preferred for EMI-critical portable applications |
| IRS2330MTRPBF | Monolithic 3-phase driver with integrated bootstrap diodes; fixed 0.6µs dead time; no RDEL or RFSH programmability | Limited configurability but smaller footprint; lacks programmable UVLO and refresh pulse | Choose IRS2330MTRPBF for cost-sensitive, space-constrained designs where flexibility is secondary to integration |
Compared with HIP4086ABZT, HIP4086AABZT trades charge-pump-based high-side bias sustainability for lower EMI and simpler layout; versus IRS2330MTRPBF, it offers superior design adaptability through programmable dead time, UVLO, and bootstrap refresh - at the cost of external component count.

FAQ
What is the key functional difference between HIP4086AABZT and HIP4086ABZT?
The HIP4086AABZT permanently disables the internal 10MHz charge pump present in the HIP4086ABZT. This eliminates a significant EMI source but requires careful bootstrap capacitor sizing to maintain high-side bias during extended on-times. The HIP4086AABZT is optimized for noise-sensitive battery-powered applications, whereas HIP4086ABZT supports indefinite high-side conduction via active charge pumping.
How is dead time programmed on the HIP4086AABZT?
Dead time on the HIP4086AABZT is set using an external resistor connected between the RDEL pin (Pin 7) and VDD. A resistor value between 10kΩ and 100kΩ yields dead times from 0.5µs to 4.5µs. If RDEL is shorted to VSS (<100mV), dead time is disabled - allowing simultaneous high/low-side activation for switched reluctance motor control.
Does HIP4086AABZT support bootstrap capacitor precharge at startup?
Yes, the HIP4086AABZT includes a programmable bootstrap refresh pulse activated at power-up or after undervoltage recovery. When triggered, it turns on all three low-side outputs (ALO/BLO/CLO) while holding off high-side outputs (AHO/BHO/CHO) to charge the bootstrap capacitors from VDD. Pulse duration is set by a capacitor on the RFSH pin (Pin 9), defaulting to ~1.5µs when unconnected.
What is the maximum allowable voltage on the xHS pins of HIP4086AABZT?
The HIP4086AABZT specifies a maximum operating voltage of 80V on the xHS pins (AHS/BHS/CHS), with transient rating up to -6V. This allows safe operation with high-voltage motor buses up to 80V DC. Exceeding this limit risks permanent damage; external clamping (e.g., dual-series diodes to VSS) is recommended to suppress negative transients during high-side FET turn-off.
Can HIP4086AABZT drive both N-channel and P-channel high-side MOSFETs?
No, the HIP4086AABZT is designed exclusively for N-channel high-side MOSFETs operated in bootstrap configuration. Its xHO outputs are level-shifted high-side drivers referenced to the floating xHS node, not ground-referenced. Driving P-channel devices would require inversion, different biasing, and is outside the specified operating conditions and validation scope of the HIP4086AABZT.
