Product details
Overview
HIP4086AABZ from Intersil (now Renesas) is a 3-phase N-channel MOSFET gate driver IC designed for PWM motor control systems. It delivers 1.25A peak turn-off current, supports 80V high-side bias voltage, and features user-programmable dead time (0.5µs–4.5µs) for shoot-through protection in brushless DC motor inverters operating up to 100kHz.
For engineers reviewing the HIP4086AABZ datasheet, HIP4086AABZ pinout, HIP4086AABZ application, or HIP4086AABZ equivalent, key selection considerations include its charge-pump-disabled architecture for low-EMI operation, bootstrap refresh pulse timing control, and programmable undervoltage lockout (6.6V–8.5V) - all critical for battery-powered motor drives requiring clean switching and robust startup behavior.
Technical Context
The HIP4086AABZ implements independent 6-channel drive logic for three half-bridge phases, with separate high-side (xHI/xHO) and low-side (xLI/xLO) input control paths. Its internal dead-time generator uses an external RDEL resistor to set delay (0.5–4.5µs), and a dedicated RFSH capacitor configures the bootstrap refresh pulse duration (typ. 1.5µs).
Unlike the HIP4086, the HIP4086AABZ permanently disables the internal 10MHz charge pump - eliminating a major EMI source while retaining full bootstrap-based high-side biasing. Undervoltage detection is programmable via UVLO pin resistor networks, enabling system-level brown-out response tuning across 6.6V–8.5V thresholds.

| 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 input | Resistor to VDD sets dead time (10kΩ–100kΩ); grounding disables dead time and shoot-through protection |

| UVLO (Pin 8) | Undervoltage threshold adjust | Resistor to VSS programs disable threshold from 6.6V (open) to 8.5V (100kΩ) |
| DIS (Pin 10) | Global disable input | Logic-high forces all six outputs low - overrides all other inputs for safe shutdown |
| VDD (Pin 20) | Positive supply | 7V–15V operation; powers logic and driver stages; requires local 0.1µF decoupling to VSS |
| VSS (Pin 6) | Ground reference | Common return for low-side FET sources and driver circuitry - must be low-impedance PCB plane |

FAQ
What is the key functional difference between HIP4086AABZ and HIP4086ABZ?
The HIP4086AABZ permanently disables the internal 10MHz charge pump present in the HIP4086ABZ. This eliminates a significant EMI source, making HIP4086AABZ ideal for battery-powered tools and medical devices where electromagnetic compatibility is critical. The HIP4086ABZ retains the charge pump to support indefinite high-side on-time, but at the cost of higher noise and quiescent current. Both share identical pinout, dead-time programming, and bootstrap architecture.
How does the HIP4086AABZ ensure reliable high-side startup?
The HIP4086AABZ uses a programmable bootstrap refresh pulse activated at power-up when VDD rises above the UVLO threshold. During this pulse, all three low-side outputs (ALO/BLO/CLO) are forced high while high-side outputs (AHO/BHO/CHO) remain off - allowing VDD to fully charge each phase's bootstrap capacitor through its external diode. The pulse duration is set by an external capacitor on the RFSH pin (typically 1.5µs open-circuit), ensuring robust startup even with large gate capacitances.
Can HIP4086AABZ drive 1000pF gate loads with specified timing?
Yes - the HIP4086AABZ is characterized to drive 1000pF loads with a typical rise time of 20ns and fall time of 10ns at VDD = 12V. This performance is achieved using 1.25A peak turn-off current and optimized internal driver stages. Layout best practices (short gate traces, local decoupling, ground plane) are required to maintain these values in production systems, especially at switching frequencies up to 100kHz.
What is the purpose of the RDEL pin, and how is dead time configured?
The RDEL pin sets the dead time between high-side and low-side driver turn-on using an external resistor to VDD. With RDEL = 10kΩ, dead time is 0.5µs; with RDEL = 100kΩ, it increases to 4.5µs. If RDEL is shorted to VSS (<100mV), dead time is disabled and outputs follow inputs directly - useful for switched reluctance control. This resistor-based configuration allows precise shoot-through margin tuning without firmware changes.
Does HIP4086AABZ support programmable undervoltage lockout, and how is it implemented?
Yes - the UVLO pin enables programmable undervoltage lockout from 6.6V to 8.5V. A resistor network between UVLO and VSS sets the threshold: open circuit yields ~6.6V, while a 100kΩ resistor raises it to ~8.5V. This allows system designers to match the disable point to battery pack voltage sag profiles or industrial bus tolerances, preventing erratic operation during brown-out conditions without external supervision circuits.
