Product details
Overview
HIP4080AIBT from Intersil (now Renesas) 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 HEN/DIS logic override. Designed for precise PWM and hysteresis-mode motor control, it delivers 10ns typical rise/fall times into 1000pF at 1MHz and supports voice coil motors, switching power amplifiers, and medium-voltage brush motor drives.
For engineers reviewing the HIP4080AIBT datasheet, HIP4080AIBT pinout, HIP4080AIBT application, or HIP4080AIBT equivalent, key selection considerations include its 55ns typical propagation delay, adjustable near-zero dead time, 80V high-side bus capability, bootstrap supply clamping at ~12.8V, and compatibility with 5V–15V logic inputs - all critical for high-fidelity load control in noise-sensitive or thermally constrained systems.
Technical Context
The HIP4080AIBT implements dual independent half-bridge drivers with level-shifted high-side outputs (AHO/BHO) and low-side outputs (ALO/BLO), each controlled by a shared comparator (IN+/IN-) and configurable turn-on delays (HDEL/LDEL). Its internal charge pump sustains AHB/BHB bias at up to 95VDC while clamping output to ~12.8V, enabling robust 80V bus operation without external high-voltage bias supplies.
Logic-level flexibility is achieved through 5V–15V-compatible DIS and HEN inputs, both with 35mV hysteresis and sub-1V low-level thresholds. The device supports four-quadrant switching via dead-time programming and includes undervoltage lockout (UV+ = 8.8V typ, UV− = 8.3V typ) with 0.4V hysteresis to prevent erratic gate drive during brownout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max High-Side Bus Voltage | 80V DC - enables direct interface with medium-voltage power stages without external level-shifting circuitry |
| Peak Output Current | ±2.5A - sufficient to drive large gate capacitances (e.g., 1000pF) at 1MHz with <25ns rise/fall times |
| Propagation Delay | 55ns typical - maximizes control-loop bandwidth and enables stable operation up to 1MHz switching frequency |
| Dead-Time Adjustment | User-programmable via external resistors on HDEL/LDEL - allows fine-tuning to eliminate shoot-through while minimizing distortion |
| Bootstrap Supply Clamp | ~12.8V - ensures consistent high-side gate overdrive across temperature and load, reducing MOSFET RDS(on) variation |
| Logic Input Range | 0V to VDD (≤15V) - supports direct interfacing with microcontrollers, DSPs, or analog comparators without level-shifting |
| Undervoltage Lockout | 8.8V rising / 8.3V falling threshold - prevents partial gate drive and MOSFET linear-mode operation during supply ramp-up/down |

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 |
|---|---|---|---|
| HIP4081AIBZ | Independent 4-channel control (no shared comparator); higher pin count (28-pin SOIC); no HEN pin | Required for applications needing individual FET timing control (e.g., synchronous rectification, phase-shifted topologies) | Select HIP4081AIBZ only when independent AHO/AHE/BHO/BHE timing is mandatory; HIP4080AIBT is preferred for cost-sensitive, comparator-driven PWM systems. |
| IRS2007PBF | Lower max bus voltage (600V half-bridge, not full-bridge); integrated bootstrap diodes; no HDEL/LDEL pins | Suitable for high-voltage half-bridge inverters (e.g., BLDC), but lacks full-bridge integration and dead-time tuning | Choose IRS2007PBF for 600V half-bridge IGBT/MOSFET drives; HIP4080AIBT remains optimal for 80V full-bridge precision motor and amplifier control. |
Compared with HIP4081AIBZ and IRS2007PBF, the HIP4080AIBT uniquely combines comparator-based full-bridge control, user-adjustable dead time, and 80V bus capability in a compact 20-pin SOIC - making it the most integrated solution for medium-voltage, high-frequency PWM motor and amplifier applications requiring minimal external components.

FAQ
What is the maximum switching frequency supported by the HIP4080AIBT?
The HIP4080AIBT supports switching frequencies up to 1MHz, verified by its ability to drive a 1000pF load with 10ns typical rise/fall times at +50°C ambient. This capability is enabled by low 55ns propagation delay and high peak output current (±2.5A), making HIP4080AIBT suitable for high-bandwidth applications like voice coil motor control and Class-D amplifiers where timing fidelity is critical.
How does the HIP4080AIBT prevent shoot-through in full-bridge operation?
The HIP4080AIBT prevents shoot-through using two independent, resistor-programmable delay paths: HDEL sets turn-on delay for high-side outputs (AHO/BHO), while LDEL sets turn-on delay for low-side outputs (ALO/BLO). This allows precise, asymmetric dead-time adjustment per half-bridge leg - confirmed in datasheet Figure 32 - ensuring one side fully turns off before the other turns on, even with MOSFET parameter mismatches.
Can the HIP4080AIBT drive high-side MOSFETs with a 75V DC bus?
Yes, the HIP4080AIBT supports high-side operation up to 80V DC bus voltage, as specified in Absolute Maximum Ratings (voltage on AHS/BHS: −6.0V transient to 80V at 25°C–125°C). Its internal charge pump and bootstrap clamp (~12.8V) maintain reliable gate overdrive across this range, and HIP4080AIBT has been validated in full-bridge power supplies and motor drives operating continuously at 75V bus.
What is the function of the HEN pin on the HIP4080AIBT?
The HEN (High-side Enable) pin on the HIP4080AIBT is a logic-level input that, when pulled low, forces both high-side outputs (AHO and BHO) into a low state regardless of IN+/IN- comparator activity. This provides hardware-level fail-safe control for high-side shutdown - essential in safety-critical motor drives - while leaving low-side outputs (ALO/BLO) unaffected unless DIS is also asserted.
Does the HIP4080AIBT require external bootstrap diodes and capacitors?
Yes, the HIP4080AIBT requires external bootstrap diodes and capacitors on both AHB and BHB pins, as explicitly stated in Pin Descriptions (Pages 7–8 of FN3658 Rev.8.00). Each bootstrap network consists of a fast-recovery diode (cathode to AHB/BHB) and a capacitor (positive terminal to AHB/BHB, negative terminal to AHS/BHS), enabling self-biasing of the high-side drivers without auxiliary supplies.
