Product details
Overview
HIP4086ABZT from Intersil (now Renesas) is a 3-phase N-channel MOSFET driver IC designed for PWM motor control, featuring independently programmable dead time (0.5–4.5 µs), 80 V high-side voltage capability, and 1.25 A peak turn-off current. It drives six external N-MOSFETs in a 3-phase bridge configuration and supports bootstrap gate drive with optional charge pump (enabled in HIP4086ABZT), making it suitable for brushless DC motor inverters in battery-powered tools and vehicles.
For engineers reviewing the HIP4086ABZT datasheet, HIP4086ABZT pinout, HIP4086ABZT application, or HIP4086ABZT equivalent, key selection considerations include its 24-pin SOIC package, programmable undervoltage lockout (6.6–8.5 V), bootstrap refresh pulse timing, and compatibility with 7–15 V bias supply and 1000 pF gate loads.
Technical Context
The HIP4086ABZT implements shoot-through protection via resistor-programmed dead time on all three half-bridges, with delay timers disabled only when RDEL voltage falls below 100 mV. Its internal charge pump-active in this variant-maintains high-side bias during indefinite on-times, eliminating boot capacitor discharge limitations typical of pure bootstrap-only drivers.
Each phase features independent logic-level inputs (xHI/xLI) with 0–15 V tolerance, level-shifted high-side outputs (xHO), and dedicated bias (xHB) and source (xHS) terminals. The device integrates a startup bootstrap refresh pulse triggered at power-up or UVLO recovery, turning on all low-side FETs while holding off high-side FETs to pre-charge boot capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 7 V to 15 V - defines minimum VDD required for reliable operation and maximum safe bias without overstressing internal regulators |
| High-Side Voltage Rating | Up to 80 V - enables direct interface with 24–48 V battery-based motor bridges without level-shifting or external HV isolation |
| Programmable Dead Time | 0.5 µs to 4.5 µs - adjustable via RDEL resistor to match switching frequency (≤100 kHz) and prevent cross-conduction in inductive loads |
| Rise/Fall Time (1000 pF) | 20 ns / 10 ns - ensures fast gate transitions for efficient switching and reduced conduction losses in high-frequency BLDC drives |
| Peak Turn-Off Current | 1.25 A - provides strong gate discharge capability to rapidly turn off high-Qg MOSFETs and minimize switching transition time |
| Undervoltage Lockout Range | 6.6 V to 8.5 V - programmable via UVLO pin resistor to prevent erratic operation during brown-out or weak-battery conditions |
| Bootstrap Refresh Pulse | Typically 1.5 µs - automatically activates at power-on to fully charge all three high-side boot capacitors before first high-side activation |
Pinout & Package
Package: 24-lead SOIC (RoHS-compliant, M24.3 drawing), rated for -40°C to +125°C ambient operation and 150°C junction temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AHO, BHO, CHO | High-side gate drive outputs | Level-shifted CMOS outputs driving gates of high-side N-MOSFETs; each referenced to its respective xHS node |
| ALO, BLO, CLO | Low-side gate drive outputs | Ground-referenced CMOS outputs driving gates of low-side N-MOSFETs; sink/source capable up to 1.25 A turn-off |
| AHI, BHI, CHI | High-side logic inputs | Inverters accepting 0–15 V logic; low input = high output; overridden by dead-time logic or DIS assertion |
| ALI, BLI, CLI | Low-side logic inputs | Direct-control inputs for low-side FETs; also used in PWM mode when tied to corresponding xHI pins |
| AHB, BHB, CHB | Bootstrap bias connections | Anode connections for external bootstrap diodes; each supplies charging path to respective boot capacitor |
| AHS, BHS, CHS | High-side source nodes | Return paths for high-side drivers; connect directly to sources of high-side power MOSFETs and negative terminals of boot caps |
| VDD | Positive supply input | Main 7–15 V bias rail; powers internal logic, charge pump (HIP4086ABZT), and level shifters; requires local 0.1 µF decoupling |
| VSS | Ground reference | Common return for low-side FET sources and internal circuitry; must be low-impedance connection to system ground plane |
| RDEL | Dead time programming | Resistor-to-VDD sets timing current; 10 kΩ–100 kΩ range yields 0.5–4.5 µs dead time; grounding disables dead time |
| UVLO | Undervoltage threshold adjust | Resistor-to-VSS programs disable threshold between 6.6 V and 8.5 V; open = ~6.6 V, tied to VDD = ~6.2 V |
| RFSH | Refresh pulse timing | Capacitor-to-VSS extends startup refresh pulse beyond default 1.5 µs; critical for large boot capacitors or high-VDD systems |
| DIS | Global disable input | Active-high override that forces all six outputs low regardless of input states; compatible with 0–15 V logic levels |
Key Features
| Feature | Design Value |
|---|---|
| Integrated charge pump | Enables true 100% duty cycle high-side drive by replenishing boot capacitor leakage; eliminates need for external charge pump circuitry |

FAQ
What is the function of the RDEL pin on the HIP4086ABZT?
The RDEL pin on the HIP4086ABZT sets the dead time between high-side and low-side driver turn-on via an external resistor to VDD. With RDEL connected through 10 kΩ–100 kΩ, dead time ranges from 0.5 µs to 4.5 µs. Grounding RDEL disables dead time entirely, allowing simultaneous high/low-side conduction - a feature used in switched reluctance motor control. The HIP4086ABZT datasheet specifies this behavior in Figure 4 and Table 1.
Does the HIP4086ABZT include an integrated charge pump?
Yes, the HIP4086ABZT includes an enabled internal charge pump, distinguishing it from the HIP4086A variants (e.g., HIP4086AABZ). This charge pump maintains high-side bias voltage during indefinite on-times, eliminating boot capacitor discharge limitations. It delivers ≥40 µA output current (per Figure 11) and operates at 10 MHz - a key differentiator confirmed in Table 1 and the Functional Description section of the HIP4086ABZT datasheet.
What is the maximum high-side voltage rating for the HIP4086ABZT?
The HIP4086ABZT supports a maximum high-side voltage (VxHS) of 80 V DC, as specified in the Absolute Maximum Ratings table on page 5 of the datasheet. This rating applies across the full operating temperature range (-40°C to +125°C ambient) and enables direct use in 24 V, 36 V, and 48 V battery-powered motor drives without external level-shifting or isolation components.
How does the bootstrap refresh pulse work in the HIP4086ABZT?
The HIP4086ABZT activates a bootstrap refresh pulse at power-up or after UVLO recovery, turning on all low-side drivers (ALO/BLO/CLO) while holding off high-side outputs (AHO/BHO/CHO) to charge all three boot capacitors from VDD through external bootstrap diodes. Duration is typically 1.5 µs but can be extended using an external capacitor on the RFSH pin, as detailed in Figure 18 and the Functional Description section.
What package type and RoHS status does the HIP4086ABZT use?
The HIP4086ABZT uses a 24-lead SOIC package (package drawing M24.3) and is RoHS-compliant, as indicated by the "Z" suffix in the part number and confirmed in the Ordering Information table on page 4 of the datasheet. It is rated for operation from -40°C to +125°C and features matte tin (e3) termination compatible with both SnPb and Pb-free soldering processes.
