Product details
Overview
HIP4080AIBZ from Renesas Electronics is a high-frequency, 80V/2.5A peak full-bridge N-channel FET driver IC in 20-lead SOIC package. It integrates input comparator, user-programmable dead-time control (via HDEL/LDEL pins), charge-pump and bootstrap biasing for high-side gate drive, and features 55ns typical propagation delay, 10ns rise/fall times at 1MHz, and undervoltage lockout. It drives voice coil motors, switching power amplifiers, and medium-voltage brush motors.
For engineers reviewing the HIP4080AIBZ datasheet, HIP4080AIBZ pinout, HIP4080AIBZ application, or HIP4080AIBZ equivalent, key selection considerations include its 80V high-side capability, adjustable dead time, bootstrap voltage clamping at ~12.8V, DIS/ HEN logic-level enable/disable control, and compatibility with 5V–15V input logic levels.
Technical Context
The HIP4080AIBZ implements a dual half-bridge architecture with independent high- and low-side gate drivers per leg (A and B), using charge-pump and bootstrap circuits to sustain upper FET bias up to 80V bus voltage. Its internal comparator enables hysteresis or PWM operation, while HEN forces freewheeling in bottom FETs and disables top FETs.
Dead time is precisely controlled via external resistors on HDEL (high-side turn-on delay) and LDEL (low-side turn-on delay) pins, each referenced to ~5.1V, preventing shoot-through. Propagation delays are asymmetric-upper turn-on (THPLH) is slower than lower turn-on (TLPLH)-to accommodate bootstrap recharge timing constraints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Bus Voltage | 80V DC - supports medium-voltage motor and power supply designs without level-shifter ICs |
| Peak Output Current | ±2.5A - drives 1000pF loads at 1MHz with 10ns rise/fall times in free air at +50°C |
| Propagation Delay | ~55ns typical - maximizes control-loop crossover frequency in closed-loop motor or amplifier systems |
| Dead Time Control | User-programmable via HDEL/LDEL resistors - enables near-zero dead time adjustment to minimize distortion |
| Bootstrap Clamp Voltage | ~12.8V - internal regulation protects high-side gate oxide and ensures stable AHB/BHB bias under varying load |
| Logic Input Range | 5V–15V compatible - interfaces directly with microcontrollers, DSPs, or analog comparators without level translation |
| UVLO Threshold | 8.8V rising / 8.3V falling - prevents erratic operation during brown-out conditions in industrial power systems |
Pinout & Package
Package: 20-lead SOIC (M20.3), RoHS-compliant, -40°C to +85°C operating range.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (BHB) | B-leg high-side bootstrap supply | Connects to cathode of bootstrap diode and positive terminal of bootstrap capacitor; supplies ~30µA charge-pump current |
| 2 (HEN) | High-side enable override | Low logic forces AHO/BHO low regardless of IN+/IN-, enabling safe freewheeling mode |
| 3 (DIS) | Global disable input | High logic pulls all four outputs (ALO/AHO/BLO/BHO) low - overrides all other controls |
| 4 (VSS) | Chip ground reference | Common return for logic, comparator, and low-side driver sections |
| 5 (OUT) | Comparator output | Open-drain output usable for feedback, hysteresis loop closure, or external monitoring |
| 6 (IN+), 7 (IN-) | Differential comparator inputs | Define bridge state (e.g., IN+ > IN- → ALO/BHO low, BLO/AHO high); support hysteresis/PWM modes |
| 8 (HDEL), 9 (LDEL) | Dead-time programming inputs | Resistor-to-VSS sets timing current; ~5.1V internal reference enables precise, temperature-stable delay tuning |
| 10 (AHB) | A-leg high-side bootstrap supply | Same function as BHB but for A-leg; independent bootstrap path prevents cross-leg coupling |
| 11 (AHO), 20 (BHO) | A/B high-side gate outputs | Drive gates of external N-channel high-side MOSFETs; level-shifted to floating AHS/BHS potentials |
| 12 (AHS), 19 (BHS) | A/B high-side source connections | Return nodes for A/B high-side MOSFET sources; connect to negative side of respective bootstrap capacitors |
| 13 (ALO), 18 (BLO) | A/B low-side gate outputs | Drive gates of N-channel low-side MOSFETs referenced to VSS; no level shift required |
| 14 (ALS), 17 (BLS) | A/B low-side source connections | Return nodes for A/B low-side MOSFET sources; tied to VSS in standard configurations |
| 15 (VCC), 16 (VDD) | Positive supply rails | VCC powers gate drivers; VDD powers logic/comparator; must be tied together and decoupled to VSS |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar full-bridge gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRS2007PBF | Integrated bootstrap diode; fixed 500ns dead time; 600V max high-side voltage; no HEN pin | Targeted at higher-voltage (>200V) induction heating and PFC, not optimized for <100kHz precision motor control | Choose IRS2007PBF only when 600V rating and integrated bootstrap are mandatory; HIP4080AIBZ offers superior timing control and flexibility |
| LM5109BMAX | Single half-bridge driver; 100V max; no comparator or HDEL/LDEL; requires external PWM generation | Suited for simpler, lower-cost half-bridge designs (e.g., fan controllers), not full-bridge or hysteresis-mode systems | Select LM5109BMAX for cost-sensitive half-bridge applications; HIP4080AIBZ is required for full-bridge, comparator-based, or dead-time–tuned designs |
Compared with IRS2007PBF and LM5109BMAX, the HIP4080AIBZ uniquely combines full-bridge integration, user-adjustable dead time, embedded comparator, and 80V/2.5A performance-making it the only option for high-fidelity, medium-voltage hysteresis or PWM-driven full-bridge systems requiring precise timing control.

FAQ
What is the maximum bus voltage supported by the HIP4080AIBZ?
The HIP4080AIBZ supports a maximum high-side voltage of 80V DC at AHS/BHS pins over the full operating temperature range (-40°C to +85°C). This rating applies under steady-state conditions; transient spikes up to -6V are allowed. The 80V limit enables use in medium-voltage industrial motor drives and power supplies without requiring external level-shifting circuitry.
How does the HIP4080AIBZ implement dead-time control?
The HIP4080AIBZ uses two dedicated pins-HDEL (Pin 8) and LDEL (Pin 9)-to set independent turn-on delays for high-side and low-side drivers. Connecting resistors from each pin to VSS establishes timing currents referenced to ~5.1V, allowing precise, temperature-stable dead-time adjustment. This prevents shoot-through by ensuring one FET fully turns off before the complementary FET begins turning on.
Can the HIP4080AIBZ drive both high-side and low-side N-channel MOSFETs in a full-bridge configuration?
Yes, the HIP4080AIBZ is explicitly designed to drive four external N-channel MOSFETs in a full-bridge topology. It provides level-shifted high-side gate drive via AHB/BHB and AHS/BHS pins with integrated charge-pump and bootstrap regulation (~12.8V clamp), while low-side drivers (ALO/BLO) operate referenced to VSS. This eliminates the need for P-channel devices or isolated supplies.
What is the purpose of the HEN pin on the HIP4080AIBZ?
The HEN (High-side Enable) pin (Pin 2) is a hardware override that forces AHO and BHO outputs low when driven low, regardless of IN+/IN- comparator state. This places the high-side FETs in cutoff and allows current to freewheel through the low-side FETs-enabling safe, controlled braking or coasting in motor applications without disrupting low-side control.
Does the HIP4080AIBZ include protection features?
Yes, the HIP4080AIBZ includes undervoltage lockout (UVLO) with 8.8V rising and 8.3V falling thresholds, preventing erratic operation during power-up/down. It also features internal bootstrap voltage clamping (~12.8V), short-circuit protected gate drivers, and logic-level DIS/ HEN pins for fast fault shutdown (<100ns propagation delay), enhancing system reliability in industrial environments.
