Product details
Overview
HIP4080AIB 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 HIP4080AIB datasheet, HIP4080AIB pinout, HIP4080AIB application, or HIP4080AIB equivalent, this page delivers verified technical context, validated pin functions, confirmed operating parameters (80V high-side voltage, 1MHz max switching, 2.5A peak output), and real-world motor/power supply use cases - all extracted from FN3658 Rev.8.00 and official Renesas documentation.
Technical Context
The HIP4080AIB implements a dual half-bridge gate driver architecture with independent high- and low-side outputs (AHO/AHS/ALO/ALS and BHO/BHS/BLO/BLS), supported by internal charge-pump and bootstrap supplies clamped to ~12.8V. Its comparator-based input stage (IN+/IN-/OUT) enables hysteresis or PWM operation, while HEN and DIS pins provide hierarchical control override.
Dead time is precisely set via external resistors on HDEL (high-side turn-on delay) and LDEL (low-side turn-on delay), each referenced to ~5.1V, preventing shoot-through. Propagation delays are asymmetric: upper turn-on (THPLH) is 70–110ns, lower turn-on (TLPLH) is 40–70ns, enabling fine-tuned timing for four-quadrant motor control and zero-dead-time optimization.

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 |
|---|---|---|---|
| HIP4081AIB | Independent 4-FET control (no shared IN+/IN- logic); separate A/B enable inputs; identical 80V/2.5A rating and SOIC-20 package. | Required for applications needing asynchronous, non-complementary switching (e.g., stepper microstepping, bidirectional buck-boost). | Select HIP4081AIB when full per-FET gate control is needed; HIP4080AIB remains optimal for standard complementary full-bridge PWM. |
| IR2104PbF | Half-bridge only (2-channel), 600V high-side capability, no integrated comparator or HDEL/LDEL; smaller 8-pin SOIC package. | Suitable for single-leg drive or cascaded full-bridge designs; lacks hysteresis mode and direct dead-time programming. | Choose IR2104PbF for cost-sensitive, lower-voltage (<60V) half-bridge needs; HIP4080AIB provides integrated full-bridge functionality with timing control. |
Compared with HIP4081AIB, HIP4080AIB offers simpler comparator-based control ideal for symmetrical PWM, while IR2104PbF requires external logic and lacks dead-time tuning - making HIP4080AIB the only option with built-in hysteresis mode, 80V rating, and user-adjustable dead time in a single full-bridge IC.

FAQ
What is the maximum bus voltage supported by the HIP4080AIB?
The HIP4080AIB supports a maximum high-side bus voltage of 80V DC at 25°C to 125°C ambient, with transient rating down to -6.0V. This is specified in the Absolute Maximum Ratings table of FN3658 Rev.8.00 and enables direct use in medium-voltage motor drives and power supplies without external level-shifting circuitry. The HIP4080AIB maintains reliable operation up to this voltage when bootstrap and charge-pump supplies are properly implemented.
How does the HIP4080AIB implement dead-time control?
The HIP4080AIB implements dead-time control via two dedicated pins: HDEL (Pin 8) and LDEL (Pin 9). Each accepts an external resistor to VSS, setting a timing current that defines the turn-on delay for high-side (HDEL) or low-side (LDEL) drivers independently. With ~5.1V internal reference voltage, this provides predictable, temperature-stable dead time - critical for preventing shoot-through in full-bridge topologies. The HIP4080AIB datasheet confirms this behavior in Pin Descriptions and Figure 32 (Minimum Dead-Time vs DEL Resistance).
Can the HIP4080AIB drive both high-side and low-side N-channel MOSFETs in a full-bridge configuration?
Yes, the HIP4080AIB is explicitly designed to drive four external N-channel MOSFETs in a full-bridge configuration - two high-side (AHS/BHS) and two low-side (ALS/BLS). It achieves high-side drive using integrated charge-pump and bootstrap circuitry, clamping the floating supply to ~12.8V. This eliminates the need for P-channel devices or isolated gate supplies. The HIP4080AIB datasheet states "Drives N-Channel FET Full Bridge Including High Side Chop Capability" in its Features section and details bootstrap connections in Pin Descriptions (Pins 1, 10, 12, 19).
What is the purpose of the HEN pin on the HIP4080AIB?
The HEN (High-side Enable) pin (Pin 2) on the HIP4080AIB provides hardware-level override of high-side gate outputs (AHO/BHO). When pulled low, HEN forces AHO and BHO into low-output state regardless of IN+/IN- comparator inputs - enabling controlled freewheeling through the bottom two external MOSFETs while keeping upper devices off. This is essential for regenerative braking and safe current decay in motor control. The HIP4080AIB datasheet specifies HEN's logic range (0–15V) and functional behavior in Pin Descriptions and Truth Table.
Does the HIP4080AIB include undervoltage lockout protection?
Yes, the HIP4080AIB includes integrated undervoltage lockout (UVLO) with rising threshold UV+ = 8.1–9.4V and falling threshold UV− = 7.6–8.9V, providing 0.25–0.65V hysteresis. This protection disables gate drive outputs when VDD/VCC drops below operational minimum, preventing erratic switching and potential shoot-through. The UVLO behavior is fully characterized in the Electrical Specifications table (Page 4) and Typical Performance Curve (Figure 31) of FN3658 Rev.8.00, confirming its operation across -40°C to +125°C junction temperature.
