Product details
Overview
HIP4086APZ from Intersil is a 3-phase N-channel MOSFET driver IC designed for PWM motor control, supporting up to 80V bridge voltage, 500mA output current per channel, and programmable dead time from 0.5µs to 4.5µs. It drives six external N-MOSFETs in a 3-phase bridge configuration and features bootstrap refresh pulse, programmable undervoltage lockout (6.6–8.5V), and 20ns/10ns rise/fall times into 1000pF loads - used in brushless DC motor drives with 24–48V battery supplies.
For engineers reviewing the HIP4086APZ datasheet, HIP4086APZ pinout, HIP4086APZ application, or HIP4086APZ equivalent, key selection considerations include its PDIP-24 RoHS-compliant package, disabled internal charge pump (distinguishing it from HIP4086), bootstrap bias management for high-side gate drive, and shoot-through protection via RDEL-programmed dead time.
Technical Context
The HIP4086APZ implements independent phase control using three pairs of logic inputs (xLI/xHI) with configurable dead time set by an external resistor on RDEL. Its internal logic enforces shoot-through prevention unless RDEL is pulled below 100mV, enabling simultaneous high/low-side conduction for switched reluctance topologies.
It integrates a bootstrap refresh pulse generator triggered at power-up or UVLO recovery, activating all low-side outputs while holding off high-side outputs to fully charge boot capacitors. The undervoltage detector uses an externally adjustable threshold (via UVLO pin) and disables all outputs when VDD falls below the programmed level.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Bridge Voltage | 80V - supports high-voltage 3-phase motor bridges up to 48V battery systems with margin. |
| Output Current | 500mA sink/source - sufficient to drive standard N-MOSFET gates with <1000pF load at 20kHz–100kHz PWM frequencies. |
| Dead Time Range | 0.5µs to 4.5µs - user-programmable via RDEL resistor to prevent shoot-through across wide operating conditions. |
| Rise/Fall Time | 20ns / 10ns (1000pF) - enables fast switching with minimal overlap loss in BLDC and AC motor inverters. |
| UVLO Threshold | 6.6V to 8.5V - adjustable via external resistor on UVLO pin to match system supply stability requirements. |
| Operating Temp | −40°C to +125°C - qualified for industrial and automotive-grade motor control environments. |
| Package | 24-pin PDIP (RoHS-compliant) - through-hole mounting compatible with wave soldering; thermal resistance θJA = 70°C/W. |
Pinout & Package
Package: 24-lead Plastic Dual In-line Package (PDIP), RoHS-compliant, θJA = 70°C/W, θJC = 29°C/W. Designed for through-hole wave solder assembly only; not reflow-compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AHO, BHO, CHO | High-side gate drive outputs | Drive gates of high-side N-MOSFETs; referenced to floating xHS pins; require external bootstrap network. |
| ALO, BLO, CLO | Low-side gate drive outputs | Drive gates of low-side N-MOSFETs; referenced to VSS; capable of 1.25A peak turn-off current. |
| AHI, BHI, CHI | High-side logic inputs | Invert logic: low input → high output; overridden by xLI during dead time; accept 0–15V signals ≤ VDD. |
| ALI, BLI, CLI | Low-side logic inputs | Direct control of low-side outputs; override corresponding xHI during dead time; accept 0–15V signals ≤ VDD. |
| AHB, BHB, CHB | Bootstrap bias connections | Anode connection point for external bootstrap diodes; each requires dedicated diode + capacitor to sustain high-side bias. |
| AHS, BHS, CHS | High-side source references | Connect to sources of high-side MOSFETs; serve as return path for bootstrap capacitor negative terminals. |
| VDD | Positive supply | 7–15V main supply; powers internal logic and charge pump (disabled in HIP4086APZ); decouple to VSS. |
| VSS | Ground reference | Common ground for low-side FET sources and logic; must be low-impedance return path for gate drive currents. |
| RDEL | Dead time programming | Resistor-to-VDD sets dead time (0.5–4.5µs); grounding disables dead time and shoot-through protection. |
| UVLO | Undervoltage threshold adjust | Resistor-to-VSS programs UVLO trip point from 6.6V to 8.5V; open = ~6.6V, tied to VDD = ~6.2V. |
| RFSH | Refresh pulse timing | Capacitor-to-VSS extends startup bootstrap refresh pulse duration beyond default 1.5µs. |
| DIS | Global disable input | Active-high signal forces all six outputs low; overrides all other inputs; accepts 0–15V logic levels. |
Key Features
| Feature | Design Value |
|---|---|
| Independent 3-phase gate drive | Drives six discrete N-MOSFETs in full-bridge topology with per-phase input control and dead-time coordination. |
| Programmable bootstrap refresh | External capacitor on RFSH extends initial low-side-only pulse to ensure full boot capacitor charging before operation. |
| Adjustable undervoltage lockout | Resistor-programmable UVLO threshold (6.6–8.5V) prevents erratic operation during brown-out or cold-start conditions. |
| Shoot-through protection | Hardware-enforced dead time eliminates cross-conduction risk without requiring precise external timing control. |
| High-noise immunity inputs | Logic inputs tolerate 0–15V swing (≤ VDD) with 35mV hysteresis, enabling robust interfacing with microcontrollers and gate drivers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-phase N-MOSFET gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HIP4086AABZ | Same functional spec but in 24-lead SOIC RoHS package; identical charge pump disable and pinout. | Preferred for surface-mount production; lower θJA (51°C/W) improves thermal performance in dense layouts. | Select HIP4086AABZ for SMT assembly; HIP4086APZ for through-hole prototyping or legacy wave-solder lines. |
| IRS2330JPbF | 600V-rated 3-phase driver with integrated bootstrap diodes; no RDEL-programmable dead time (fixed 0.6µs). | Suitable for higher-voltage AC induction drives; lacks refresh pulse and UVLO adjustability. | Choose IRS2330JPbF only if >100V bridge operation is required; HIP4086APZ offers superior configurability for <80V BLDC systems. |
Compared with HIP4086AABZ, HIP4086APZ trades thermal efficiency for through-hole manufacturability; compared with IRS2330JPbF, it delivers finer dead-time tuning and startup reliability at lower voltage ratings - making it optimal for cost-sensitive, thermally moderate 24–48V motor control designs.

FAQ
What is the key functional difference between HIP4086APZ and HIP4086?
The HIP4086APZ has its internal charge pump permanently disabled, unlike the HIP4086 which includes an active charge pump. This makes HIP4086APZ suitable for low-EMI applications where 10MHz charge pump noise must be avoided. However, HIP4086APZ relies solely on bootstrap capacitors for high-side bias, limiting maximum duty cycle without external refresh circuitry - a trade-off explicitly documented in the FN4220 datasheet.
Does HIP4086APZ support 100% duty cycle high-side drive?
No - HIP4086APZ does not support indefinite 100% duty cycle high-side conduction because its internal charge pump is disabled. Without the charge pump, the bootstrap capacitor discharges over time during sustained high-side on-time. Designers must limit continuous high-side on-time or implement external refresh mechanisms; the datasheet specifies that HIP4086 (not HIP4086APZ) enables indefinite high-side on-time via its active charge pump.
How is dead time programmed on HIP4086APZ?
Dead time on HIP4086APZ is programmed using an external resistor connected between RDEL (Pin 7) and VDD. Values from 10kΩ to 100kΩ yield dead times from 0.5µs to 4.5µs. If RDEL is shorted to VSS (<100mV), dead time is disabled and high/low-side outputs can be driven simultaneously - a feature used in switched reluctance motor control per the FN4220 datasheet truth table.
What is the purpose of the RFSH pin on HIP4086APZ?
The RFSH (Pin 9) on HIP4086APZ controls the duration of the bootstrap refresh pulse activated at power-up or after UVLO recovery. An external capacitor from RFSH to VSS extends the default 1.5µs pulse, ensuring full charging of all three bootstrap capacitors before normal operation begins - critical for reliable high-side turn-on in motor start-up sequences.
Can HIP4086APZ drive both N-channel and P-channel MOSFETs?
No - HIP4086APZ is designed exclusively for driving N-channel MOSFETs in a 3-phase bridge configuration. Its architecture assumes high-side N-MOSFETs driven via bootstrap networks and low-side N-MOSFETs referenced to VSS. It does not support P-channel high-side configurations or integrated driver-FET modules; this limitation is inherent to its gate drive topology and pin definitions in the FN4220 datasheet.
