Renesas HIP4082IBZTR5676

Overview

HIP4082IBZTR5676 from Intersil is an 80V, 1.25A peak current H-bridge N-channel MOSFET driver IC in 16-lead SOIC (N) package, designed for PWM motor control and UPS systems. It features independently programmable dead time (0.1–4.5μs), non-latching level-shifted high-side drive, and shoot-through protection. Its bootstrap supply supports up to 95VDC, enabling use in medium-power DC motor and full-bridge power supply applications.

For engineers reviewing the HIP4082IBZTR5676 datasheet, HIP4082IBZTR5676 pinout, HIP4082IBZTR5676 application, or HIP4082IBZTR5676 equivalent, key selection considerations include its 80V high-side voltage rating, 15ns typical rise/fall times into 1000pF, 50kHz–200kHz switching frequency support, and compatibility with 5V–15V logic input levels across –55°C to +125°C operation.

Technical Context

The HIP4082IBZTR5676 implements dual independent half-bridge drivers with non-latching level-shift translation for AHB/BHB high-side outputs, eliminating need for internal charge pump. Its DEL pin sets dead time via external resistor, enabling precise control of turn-on delay between complementary low- and high-side gate outputs to prevent shoot-through.

It integrates undervoltage protection on both VDD (6.5–8.5V trip) and high-side bias rails (4.5–7.5V referenced to AHS/BHS), plus DIS input that overrides all controls to force all outputs low while refreshing bootstrap capacitors. Input logic thresholds are compatible with 5V–15V CMOS/TTL signals without level-shifting.

FAQ

What is the maximum allowable voltage on the AHS and BHS pins of the HIP4082IBZTR5676?

The HIP4082IBZTR5676 supports up to 80V on AHS and BHS pins at 25°C, derating to 70V over the full –55°C to +125°C operating range. This rating defines the maximum floating voltage between high-side source and system ground, enabling safe operation with 48V–72V bus voltages in full-bridge topologies. Exceeding these limits risks permanent damage to the level-shift circuitry.

How does the DEL pin configure dead time in the HIP4082IBZTR5676?

The DEL pin on the HIP4082IBZTR5676 sinks a current proportional to (VDD – 2V)/R_DEL, which sets the turn-on delay for all four gate outputs. With R_DEL = 100kΩ, dead time is typically 4.5μs; with R_DEL = 10kΩ, it reduces to 0.5μs. This hardware-based delay guarantees shoot-through immunity regardless of input timing skew, making the HIP4082IBZTR5676 inherently robust in noisy or asynchronous control environments.

Does the HIP4082IBZTR5676 include an internal charge pump?

No, the HIP4082IBZTR5676 does not contain an internal charge pump. Instead, it uses non-latching level-shift translation for high-side drive, requiring external bootstrap diodes and capacitors connected to AHB/BHB and AHS/BHS pins. This architecture reduces quiescent current and simplifies thermal design but mandates proper bootstrap component selection-especially for high-duty-cycle or low-frequency PWM applications where capacitor recharge must be ensured.

What logic voltage levels are compatible with HIP4082IBZTR5676 inputs (ALI, BLI, AHI, BHI, DIS)?

The HIP4082IBZTR5676 accepts logic input voltages from 0V to VDD (max +15V), with guaranteed recognition of low-level signals ≤1.0V and high-level signals ≥2.5V across –55°C to +125°C. This 5V–15V compatibility allows direct interfacing with microcontrollers, DSPs, and analog comparators without level-shifting circuitry-reducing BOM count and layout area while maintaining noise margin in electrically harsh motor drive environments.

What protection features are integrated into the HIP4082IBZTR5676?

The HIP4082IBZTR5676 integrates shoot-through prevention via hardware-enforced dead time and input priority logic, plus dual undervoltage lockout (UVLO) on VDD (6.5–8.5V trip) and high-side bias rails (4.5–7.5V referenced to AHS/BHS). These protections operate independently and autonomously-no external components or firmware required-to prevent destructive cross-conduction or erratic switching during power-up, brown-out, or bootstrap capacitor depletion events.
