Product details
Overview
HIP4082IBZ from Intersil is a medium-frequency, 80V-rated H-bridge N-channel MOSFET driver IC in 16-lead SOIC (N) package, delivering 1.25A peak gate drive current with user-programmable dead time (0.1–4.5µs), shoot-through protection, and non-latching level-shifted high-side control - designed for PWM motor control and UPS systems.
For engineers reviewing the HIP4082IBZ datasheet, HIP4082IBZ pinout, HIP4082IBZ application, or HIP4082IBZ equivalent, key selection criteria include bootstrap-compatible 80V high-side operation, independent half-bridge control logic, undervoltage lockout thresholds (6.5–8.5V), 15ns typical rise/fall times into 1000pF, and Pb-free RoHS-compliant packaging.
Technical Context
The HIP4082IBZ implements dual independent high-side drivers with non-latching level-shift translation-no internal charge pump-and two low-side drivers, all controlled via TTL/CMOS-compatible inputs (0–15V logic). Its flexible input protocol supports both independent and bistate bridge modes, with DIS pin overriding all inputs to force outputs low while refreshing bootstrap capacitors.
Dead time is set externally via a single resistor on the DEL pin, enabling precise timing control (0.1–4.5µs) across temperature and supply voltage variations. Undervoltage protection operates separately on VDD (6.5–8.5V trip) and high-side bias rails (4.5–7.5V referenced to AHS/BHS), ensuring safe turn-off during brownout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Supply Voltage | 80V on AHS/BHS pins - enables direct interface with medium-power motor and UPS bus voltages without external level-shifting. |
| Peak Output Current | 1.25A source/sink - sufficient to rapidly charge/discharge 1000pF gate capacitance with 15ns typical edge speeds. |
| Programmable Dead Time | 0.1–4.5µs via DEL pin resistor - prevents shoot-through in high-frequency switching up to 200kHz. |
| Logic Input Range | 0–15V compatible - allows direct connection to microcontrollers, PWM controllers, or isolated gate drivers without level-shifting. |
| Undervoltage Lockout | VDDUV− = 6.5V min, VHBUV = 4.5V min - ensures reliable disable before gate drive capability degrades at low bias. |
| Rise/Fall Time | Typically 15ns into 1000pF - supports fast switching transitions critical for efficiency in PWM motor drives. |
| Operating Temp Range | −55°C to +125°C - qualified for industrial and automotive under-hood environments. |
Pinout & Package
Package: 16-lead SOIC (N), 3.90mm × 9.90mm body, 1.27mm pitch, Pb-free (RoHS compliant), JEDEC MS-012-AC / M16.15 footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BHB | B-side high-side bootstrap supply | Connects external bootstrap diode cathode and capacitor positive terminal - supplies floating bias for BHO driver. |
| BHI | B high-side input | Controls BHO output; overridden by BLI or DIS to prevent shoot-through per truth table logic. |
| BLI | B low-side input | Controls BLO output; when BHI unasserted, also controls BHO with programmable dead time. |
| ALI | A low-side input | Controls ALO output; when AHI unasserted, also controls AHO with same dead time as BLI path. |
| DEL | Dead-time programming | Resistor-to-VSS sets timing current defining minimum off-time between complementary A/B outputs. |
| VSS | Ground reference | Chip substrate and low-side driver return - must be low-impedance path for gate drive return currents. |
| DIS | Global disable | Active-high input forcing all four outputs low; refreshes bootstrap capacitors when pulled low. |
| AHI | A high-side input | Controls AHO output; overridden by ALI or DIS - ensures only one high-side switch enabled per half-bridge. |
| AHO | A high-side output | Drives gate of external N-channel MOSFET connected to AHS - requires bootstrap circuit for high-side operation. |
| BLO | B low-side output | Direct low-side gate driver - sinks/source up to 1.25A to switch N-MOSFET with minimal propagation delay (25–70ns). |
| ALO | A low-side output | Direct low-side gate driver - matches BLO specs; used in full-bridge or dual half-bridge topologies. |
| VDD | Logic & low-side supply | +8.5V to +15V input powering internal logic, level shifters, and low-side drivers - decoupling required. |
| AHB | A-side high-side bootstrap supply | Connects external bootstrap diode cathode and capacitor positive terminal - supplies floating bias for AHO driver. |
| AHS | A high-side source reference | Connects to source of A high-side MOSFET - serves as local ground reference for AHO driver and bootstrap capacitor negative terminal. |
| BHS | B high-side source reference | Connects to source of B high-side MOSFET - serves as local ground reference for BHO driver and bootstrap capacitor negative terminal. |
Key Features
| Feature | Design Value |
|---|---|
| Independent half-bridge control | Each half-bridge (A and B) accepts separate high/low inputs, enabling asymmetric PWM or phase-shifted operation without external logic. |
| Bootstrap-compatible high-side drive | Supports up to 95V bootstrap supply voltage - allows use with 80V bus designs while maintaining >15V gate overdrive margin. |
| Shoot-through prevention logic | Hardware-enforced interlock: ALI overrides AHI, BLI overrides BHI, and DIS overrides all - eliminates risk of cross-conduction in PCB layout. |
| Wide logic voltage compatibility | Inputs accept 0–15V signals - interfaces directly with 3.3V, 5V, or 12V controllers without level translators or pull-ups. |
| Refreshable bootstrap on disable | When DIS is pulled low, ALO/BLO pulse briefly to recharge bootstrap capacitors - maintains high-side gate voltage during idle periods. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar H-bridge gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HIP4081IBZ | Higher 2.0A peak drive current; narrower dead-time range (0.2–2.0µs); includes internal charge pump. | Better suited for higher gate charge MOSFETs or faster switching (>200kHz); less flexibility in dead-time tuning. | Select HIP4081IBZ when driving >2000pF loads or requiring tighter dead-time control at high frequency. |
| IRS2007PBF | Integrated bootstrap diodes; 600V high-side rating; fixed 0.6µs dead time; 1.5A peak current. | Targeted for high-voltage PFC and audio amplifiers; not optimized for <80V motor control due to higher VTH and fixed timing. | Choose IRS2007PBF for 400V+ applications or where integrated bootstrap simplifies layout - not drop-in for HIP4082IBZ. |
Compared with HIP4082IBZ, HIP4081IBZ offers higher drive strength but reduced dead-time adjustability, while IRS2007PBF trades programmability for high-voltage integration - making HIP4082IBZ optimal for cost-sensitive, medium-voltage motor control where timing flexibility and bootstrap simplicity are prioritized.

FAQ
What is the maximum operating voltage on the AHS and BHS pins of the HIP4082IBZ?
The HIP4082IBZ supports a maximum continuous voltage of 70V on AHS and BHS pins at −55°C to +150°C, and up to 80V at 25°C to +150°C. Transient ratings allow −6V to 80V, making it suitable for 48V and 72V battery-fed motor and UPS applications. These ratings are defined in the Absolute Maximum Ratings table on page 5 of the FN3676 datasheet.
Does the HIP4082IBZ include an internal charge pump?
No, the HIP4082IBZ does not contain an internal charge pump. It relies on external bootstrap circuits (diode + capacitor) connected to AHB and BHB pins for high-side gate drive. This design reduces complexity and cost compared to charge-pump-based drivers like the HIP4081, while maintaining robust level-shifted operation up to 80V.
How is dead time programmed on the HIP4082IBZ?
Dead time on the HIP4082IBZ is programmed using a single resistor connected between the DEL pin and VSS. With RDEL = 100kΩ, typical dead time is 4.5µs; with RDEL = 10kΩ, it reduces to 0.5µs. The relationship is monotonic and specified across temperature - Figure 16 in the FN3676 datasheet provides exact curves for 9V, 12V, and 15V VDD.
What happens to the bootstrap capacitors when the DIS pin is asserted low on the HIP4082IBZ?
When the DIS pin is pulled low, the HIP4082IBZ forces ALO and BLO outputs to pulse briefly (375–950ns), actively discharging and then recharging the bootstrap capacitors connected to AHB and BHB. This "refresh" function ensures high-side gate drive remains available after extended disable periods - a key feature distinguishing HIP4082IBZ from simpler drivers lacking this capability.
Is the HIP4082IBZ pin-compatible with the HIP4082IPZ DIP package version?
Yes, the HIP4082IBZ (SOIC) and HIP4082IPZ (PDIP) share identical pin numbering, pin functions, and electrical specifications - differing only in package type and thermal characteristics (θJA = 115°C/W vs. 90°C/W). Layout adaptation is required due to SOIC's smaller footprint and lead pitch, but no schematic or logic changes are needed for migration between these variants.
