Product details
Overview
HIP4082IPZ from Intersil is a medium-frequency, 80V-rated H-bridge N-channel MOSFET driver IC in a 16-lead PDIP 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 HIP4082IPZ datasheet, HIP4082IPZ pinout, HIP4082IPZ application, or HIP4082IPZ equivalent, key selection considerations include bootstrap-based high-side operation up to 80V, logic-level input compatibility (5–15V), disable-driven bootstrap refresh, and thermal performance in through-hole wave-soldered industrial power stages.
Technical Context
The HIP4082IPZ implements dual independent half-bridge drivers with non-latching level-shift translation for AHB/BHB high-side control, eliminating internal charge pumps while supporting bootstrap supplies up to 95VDC. Its architecture enforces shoot-through prevention via input priority logic (e.g., ALI overrides AHI) and hardware-enforced dead time set by external DEL resistor.
It features undervoltage lockout on both VDD (6.5–8.5V hysteresis) and high-side bias rails (4.5–7.5V referenced to AHS/BHS), plus DIS pin override that forces all outputs low and actively refreshes bootstrap capacitors - critical for reliable restart in motor control and battery-powered vehicle inverters.
Key Specifications

| 12 (VDD) | Positive Supply | +8.5V to +15V supply for logic and low-side drivers; requires local decoupling to VSS. |

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 |
|---|---|---|---|
| HIP4081IPZ | Higher 2.0A peak drive current; narrower dead time range (0.2–2.0µs); includes internal charge pump. | Better suited for higher-power, lower-voltage (<60V) bridges with faster FETs requiring stronger gate drive. | Select HIP4081IPZ when driving low-Rds(on) MOSFETs below 60V where charge-pump stability outweighs dead time flexibility. |
| IR2184SPBF | Fixed 0.6µs dead time; 600V high-side rating; integrated bootstrap diode; 2.5A peak current. | Targeted at higher-voltage AC-DC and PFC stages; lacks programmable dead time and DIS-driven bootstrap refresh. | Choose IR2184SPBF for 100–400V half-bridge applications where integrated diode simplifies layout but programmability is not required. |
Compared with HIP4081IPZ and IR2184SPBF, the HIP4082IPZ offers uniquely wide dead time tuning (0.1–4.5µs) and DIS-triggered bootstrap refresh - making it optimal for 48–80V motor and UPS designs demanding robustness across variable load and temperature conditions.

FAQ
What is the maximum bootstrap supply voltage supported by the HIP4082IPZ?
The HIP4082IPZ supports a maximum bootstrap supply voltage of 95VDC on pins AHB and BHB. This rating allows safe operation with high-side source voltages up to 80V (AHS/BHS), accommodating transient overvoltage margins. The device does not contain an internal charge pump, so external bootstrap diodes and capacitors must be selected to withstand this voltage and provide sufficient hold-up time during PWM duty cycles. Always verify bootstrap capacitor voltage rating and ESR per application requirements.
How does the DIS pin function in the HIP4082IPZ, and what design benefit does it provide?
The DIS pin on the HIP4082IPZ is an active-high disable input that overrides all other control inputs to force ALO, BLO, AHO, and BHO low. Critically, when DIS is pulled low, it also triggers a refresh pulse that recharges the bootstrap capacitors - preventing gate drive collapse during extended off-states. This feature is essential in motor control and UPS applications where intermittent operation or fault recovery requires guaranteed high-side gate voltage restoration without external circuitry. The HIP4082IPZ uses this mechanism to maintain reliability across wide temperature and load variations.
Can the HIP4082IPZ drive both high-side and low-side N-channel MOSFETs in a full-bridge configuration?
Yes, the HIP4082IPZ is explicitly designed to independently drive four N-channel MOSFETs in full-bridge or dual half-bridge topologies. It provides two level-shifted high-side drivers (AHO and BHO) with non-latching translation referenced to AHS and BHS, plus two ground-referenced low-side drivers (ALO and BLO). Each high-side output supports bootstrap operation up to 80V, and all outputs deliver 1.25A peak current. The HIP4082IPZ truth table and input priority logic ensure safe commutation without shoot-through, making it ideal for bidirectional motor control and inverter applications.
What is the purpose of the DEL pin on the HIP4082IPZ, and how is dead time calculated?
The DEL pin on the HIP4082IPZ sets the user-programmable dead time between high-side and low-side driver turn-on via an external resistor to VSS. The timing current flowing through this resistor determines the delay - approximately 0.1µs to 4.5µs depending on resistance value and VDD. For example, with RDEL = 100kΩ and VDD = 12V, typical dead time is 4.5µs. This hardware-enforced blanking interval prevents shoot-through by ensuring one FET is fully off before the complementary FET turns on. The HIP4082IPZ guarantees this timing without software intervention or additional components.
Is the HIP4082IPZ compatible with 3.3V logic microcontrollers?
The HIP4082IPZ is not directly compatible with 3.3V logic because its input high-level threshold (VIH) is specified as minimum 2.5V at full operating conditions, but the recommended operating range starts at 5V logic levels. While some units may respond to 3.3V inputs under controlled lab conditions, the datasheet specifies reliable operation only with 5V–15V logic signals. To interface with 3.3V microcontrollers, a level-shifter or buffer (e.g., 74LVC1G17) is required to translate signals into the HIP4082IPZ's valid input range. Using 3.3V directly risks marginal switching and undefined behavior across temperature and process variation.
