Product details
Overview
HIP4086ABT from Intersil (now Renesas) is a 3-phase N-channel MOSFET gate driver IC designed for PWM motor control, featuring independent high- and low-side drive per phase, programmable dead time (0.5–4.5 µs), 80 V high-side floating voltage capability, and bootstrap refresh pulse functionality. It targets brushless DC and switched reluctance motor drives in battery-powered tools and vehicles.
For engineers reviewing the HIP4086ABT datasheet, HIP4086ABT pinout, HIP4086ABT application, or HIP4086ABT equivalent, key selection criteria include its charge-pump-disabled variant status, 24-pin SOIC package, undervoltage set point programmability (6.6–8.5 V), and compatibility with 1000 pF gate loads achieving 20 ns rise / 10 ns fall times.
Technical Context
The HIP4086ABT implements shoot-through protection via user-programmable RDEL resistor-controlled turn-on delay timers (disabled when RDEL < 100 mV), and integrates a startup bootstrap refresh pulse activated on VDD power-up or UVLO recovery to precharge all three high-side boot capacitors by enabling low-side FETs while holding off high-side outputs.
It features dual-input logic per phase (xHI/xLI), supports PWM-mode operation with internal dead time enforcement, and includes a dedicated DIS pin that overrides all inputs to force all six outputs low - critical for safe shutdown in motor control safety chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Driver Type | 3-phase N-channel MOSFET bridge driver with independent high/low-side outputs per phase |
| High-Side Voltage Range | Up to 80 V on xHS pins - enables direct drive of high-voltage motor bridges without level-shifting |
| Dead Time Range | 0.5 µs to 4.5 µs (programmed via RDEL resistor) - prevents shoot-through in PWM-controlled inverters |
| Rise/Fall Time | 20 ns / 10 ns into 1000 pF load - ensures fast switching for efficient motor control up to 100 kHz |
| Undervoltage Threshold | Programmable 6.6 V to 8.5 V (via UVLO pin resistor) - configurable brown-out protection for battery-fed systems |
| Bootstrap Refresh Pulse | Programmable duration (via RFSH capacitor) - guarantees full boot capacitor charge before first high-side activation |
| Charge Pump | Permanently disabled - eliminates 10 MHz EMI source, suited for noise-sensitive applications |
Pinout & Package
Package: 24-lead SOIC (RoHS-compliant, M24.3 drawing), rated for -40°C to +125°C ambient operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AHO, BHO, CHO | High-side gate drive outputs | Drive gates of high-side N-MOSFETs; referenced to respective xHS pins; tolerate up to 95 V bootstrap supply |
| ALO, BLO, CLO | Low-side gate drive outputs | Drive gates of low-side N-MOSFETs; referenced to VSS; sink 1.25 A peak during turn-off |
| AHI, BHI, CHI | High-side logic inputs | Invert logic: low input → high output; compatible with 0–15 V logic levels (≤ VDD) |
| ALI, BLI, CLI | Low-side logic inputs | Direct logic: high input → high output; compatible with 0–15 V logic levels (≤ VDD) |
| AHB, BHB, CHB | High-side bias connections | Connect external bootstrap diode anode and capacitor positive terminal; supply path for high-side driver bias |
| AHS, BHS, CHS | High-side source connections | Connect to sources of high-side power MOSFETs; serve as local ground reference for high-side drivers |
| VDD | Positive supply input | 7–15 V main supply; powers logic and low-side drivers; requires local 0.1 µF decoupling to VSS |
| VSS | Ground reference | Common return for low-side FET sources and logic ground; must be low-impedance connection |
| RDEL | Dead time programming input | Resistor-to-VDD sets dead time (0.5–4.5 µs); grounding disables dead time and shoot-through protection |
| UVLO | Undervoltage threshold programming | Resistor-to-VSS sets disable threshold between 6.6 V and 8.5 V; open = ~6.6 V typical |
| RFSH | Refresh pulse timing | Capacitor-to-VSS extends startup bootstrap refresh pulse beyond default 1.5 µs |
| DIS | Global disable input | Active-high override: forces all six outputs low regardless of other inputs; critical for fail-safe shutdown |
Key Features
| Feature | Design Value |
|---|---|
| Independent 6-channel drive | Enables flexible commutation schemes (e.g., 120° or 180° BLDC, SRM) without external logic |
| Programmable dead time | Adjustable via single resistor (RDEL) - eliminates need for external timing components or microcontroller compensation |
| Bootstrap refresh pulse | Guarantees reliable high-side turn-on at power-up - prevents boot capacitor undercharge failure in motor start sequences |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-phase gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HIP4086ABZ | Same pinout and function, but includes enabled internal charge pump (not disabled) | Suitable where indefinite high-side on-time is required (e.g., 100% duty cycle phases) | Select HIP4086ABZ only if charge pump functionality is needed; HIP4086ABT avoids EMI from 10 MHz pump clock |
| IRS2330MTRPBF | Monolithic 3-phase driver with built-in bootstrap diodes; no external RDEL/UVLO programming; fixed 500 ns dead time | Limited configurability but smaller footprint; lacks programmable refresh and UVLO | Choose IRS2330MTRPBF for cost-sensitive, space-constrained designs where fixed timing suffices and EMI tolerance permits integrated diodes |
Compared with HIP4086ABZ, HIP4086ABT trades charge-pump-enabled 100% duty-cycle support for lower EMI and simpler biasing; versus IRS2330MTRPBF, it offers superior design flexibility via resistor-programmable dead time, UVLO, and refresh pulse - at the cost of two external components per phase.

FAQ
What is the key functional difference between HIP4086ABT and HIP4086ABZ?
The HIP4086ABT has its internal charge pump permanently disabled - reducing EMI and simplifying biasing - whereas the HIP4086ABZ includes an active charge pump to sustain high-side bias during indefinite on-times. Both share identical pinout, dead time programming, and bootstrap refresh functionality. The HIP4086ABT is selected when EMI performance is prioritized over 100% duty cycle capability.
How does the HIP4086ABT implement shoot-through protection?
The HIP4086ABT uses resistor-programmed turn-on delay timers (via RDEL pin) to enforce dead time between high- and low-side driver activation. When RDEL voltage exceeds 100 mV, delays are active; grounding RDEL disables protection entirely. This allows designers to choose between guaranteed shoot-through immunity or intentional overlap for switched reluctance motor control - a feature confirmed in the HIP4086ABT datasheet truth table and functional description.
Can HIP4086ABT drive 1000 pF gate loads at 100 kHz switching frequency?
Yes. The HIP4086ABT delivers 20 ns rise and 10 ns fall times into 1000 pF loads per channel, and its AC specifications confirm stable operation up to 100 kHz - matching typical BLDC and AC induction motor drive frequencies. Its 1.25 A peak turn-off current and low propagation delays (<158 ns max upper turn-on) ensure reliable high-frequency switching without gate waveform distortion.
What is the purpose of the RFSH pin on HIP4086ABT?
The RFSH pin on HIP4086ABT accepts an external capacitor to extend the duration of the bootstrap refresh pulse at power-up. By default, the pulse lasts ~1.5 µs; adding capacitance increases this time linearly, ensuring full charging of all three high-side boot capacitors before normal operation begins - critical for reliable first-cycle high-side activation in motor start sequences.
Does HIP4086ABT support programmable undervoltage lockout?
Yes. The HIP4086ABT's UVLO pin accepts a resistor-to-VSS to set the VDD undervoltage disable threshold anywhere from 6.6 V to 8.5 V. With UVLO open, the threshold is typically 6.6 V; tying UVLO to VDD lowers it to ~6.2 V. This programmability allows precise matching to battery pack voltage profiles - a confirmed specification in the HIP4086ABT DC electrical table and functional description.
