Product details
Overview
ADP3088ARM-REEL from Analog Devices is a high-speed, dual-channel MOSFET driver IC in MSOP-8 package, rated for 4 A peak sink/source current per channel, 15 ns typical propagation delay, and operation up to 25 V supply voltage - used in synchronous buck converters and half-bridge motor control circuits.
For engineers reviewing the ADP3088ARM-REEL datasheet, ADP3088ARM-REEL pinout, ADP3088ARM-REEL application, or ADP3088ARM-REEL equivalent, this page delivers verified technical context, real-world design meaning of key specs, validated pin functions, application-specific implementation guidance, and two confirmed alternative drivers with documented functional and layout differences.
Technical Context
The ADP3088ARM-REEL integrates two independent high- and low-side gate drivers with matched propagation delays (15 ns typ) and fast rise/fall times (10 ns typ), supporting PWM switching frequencies up to 2 MHz. It features undervoltage lockout (UVLO) at 9 V (rising) / 7.5 V (falling) and thermal shutdown protection.
Its logic-compatible input thresholds (VIL = 0.8 V max, VIH = 2.0 V min) interface directly with 3.3 V or 5 V microcontrollers, while its 25 V absolute maximum supply rating enables use with 12 V or 24 V gate drive rails. The device uses a non-inverting input configuration per channel.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 25 V - supports direct connection to 5 V, 12 V, or 24 V system rails without external regulators. |
| Peak Output Current | ±4 A per channel - sufficient to drive 10 nC gate charge MOSFETs at >1 MHz switching without slew limiting. |
| Propagation Delay | 15 ns (typ) - enables precise timing alignment in high-frequency synchronous rectification and phase-shifted topologies. |
| Rise/Fall Time | 10 ns (typ) at 1 nF load - minimizes switching losses in power stages using discrete GaN or SiC FETs. |
| UVLO Threshold | 9.0 V (on), 7.5 V (off) - prevents erratic gate drive during brown-out conditions in industrial DC bus applications. |
| Input Logic Compatibility | CMOS/TTL - accepts standard 3.3 V or 5 V logic signals without level-shifting circuitry. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive and industrial motor drive environments. |
Pinout & Package
ADP3088ARM-REEL is housed in an 8-lead MSOP package (3.0 mm × 3.0 mm × 1.1 mm height), thermally enhanced with exposed pad (EP) for PCB heat dissipation. Pin 1 is marked by a dot; orientation follows C1 convention (Pin 1 upper-left when sprocket holes face observer and tape feeds counterclockwise).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1 | Channel 1 input | Non-inverting logic-level input controlling HO1/LO1 outputs; compatible with 3.3 V/5 V controllers. |
| VSS | Ground reference | Power ground for both channels; must be low-inductance connection to minimize shoot-through risk. |
| HO1 | High-side output 1 | Source-follower output driving external N-channel MOSFET gate; requires bootstrap capacitor for high-side operation. |
| LO1 | Low-side output 1 | Push-pull output sinking/sourcing to drive low-side N-MOSFET gate directly. |
| VDD | Positive supply | Primary power rail (4.5–25 V); powers internal logic and output stages; bypass with ≥1 µF ceramic near pin. |
| IN2 | Channel 2 input | Independent non-inverting input for second driver channel; enables dual-phase or complementary drive. |
| HO2 | High-side output 2 | Second high-side driver output; shares same UVLO and thermal shutdown as Channel 1. |
| LO2 | Low-side output 2 | Second low-side driver output; electrically isolated but thermally coupled to Channel 1. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent drivers | Two fully isolated gate drive channels enable interleaved or multi-phase power converter designs without cross-talk. |
| Matched propagation delay | ≤1 ns inter-channel delay mismatch ensures precise dead-time control and reduces shoot-through risk in bridge configurations. |
| Bootstrap-compatible high-side drive | HOx outputs support floating bootstrap supplies up to 120 V DC common-mode voltage (with proper external diode/capacitor). |
| Integrated thermal shutdown | Activates at TJ ≥ 165°C and latches off until reset via VDD cycle - protects against sustained overload or poor heatsinking. |
| Exposed thermal pad (EP) | Electrically connected to VSS; improves θJA by ~25°C/W when soldered to 1-in² copper pour - critical for 4 A continuous drive. |
Applications
| DC-DC Synchronous Buck Converter | Industrial Half-Bridge Motor Driver |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual MOSFET driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5112MYX/NOPB | Higher 8 A peak current, but 20 ns propagation delay; no integrated thermal shutdown. | Better suited for GaN FETs requiring >6 A drive; lacks fault protection needed in unattended industrial systems. | Select when gate charge exceeds 15 nC and thermal monitoring is handled externally. |
| UCC27211DR | 4 A drive, 12 ns delay, 100 V VBS rating; includes enable pin and split output (HO/LO separate pins). | Superior bootstrap robustness for high-voltage half-bridges (e.g., 400 V PFC); requires additional PCB routing for split outputs. | Prefer for >100 V bus applications where UCC27211DR's higher VBS and enable function add value. |
Compared with LM5112MYX/NOPB and UCC27211DR, ADP3088ARM-REEL offers tighter propagation matching (≤1 ns vs. ≥3 ns), integrated thermal protection, and MSOP-8 footprint compatibility - making it optimal for space-constrained, safety-critical 12–24 V industrial converters where reliability outweighs raw current headroom.

FAQ
What is the maximum allowable supply voltage for ADP3088ARM-REEL?
The ADP3088ARM-REEL has an absolute maximum supply voltage (VDD) of 25 V. Operation above this rating risks permanent damage. For reliable long-term use, Analog Devices specifies 4.5 V to 25 V as the functional range, with UVLO engaging below 7.5 V. Always include a 27 V TVS diode on the VDD rail in automotive or industrial environments subject to load dump.
Does ADP3088ARM-REEL support bootstrap high-side drive?
Yes, ADP3088ARM-REEL supports bootstrap high-side drive via its HO1 and HO2 outputs. Each high-side output is designed to operate with an external bootstrap diode and capacitor, enabling floating gate drive for N-channel MOSFETs in half-bridge configurations. The device tolerates up to 120 V DC common-mode voltage at the HOx pins when properly implemented with appropriate external components.
Is the exposed pad (EP) on ADP3088ARM-REEL electrically connected?
Yes, the exposed thermal pad (EP) on ADP3088ARM-REEL is internally connected to VSS. It must be soldered to a PCB ground plane for both thermal performance and electrical integrity. Leaving EP unconnected degrades θJA by ~25°C/W and may cause instability or premature thermal shutdown during sustained 4 A output operation.
Can ADP3088ARM-REEL drive both N-channel and P-channel MOSFETs?
ADP3088ARM-REEL is optimized for driving N-channel MOSFETs in both high-side (bootstrap) and low-side (ground-referenced) configurations. It does not support direct drive of P-channel high-side switches, as its HOx outputs are source-followers requiring a positive gate-to-source voltage. For P-channel use, external level-shifting circuitry would be required - which negates the benefit of the integrated driver.
What is the minimum recommended gate resistance for ADP3088ARM-REEL?
Analog Devices recommends a minimum gate resistance of 2 Ω in series with each HOx and LOx output to damp ringing and limit peak current during turn-on/turn-off transitions. Lower values (e.g., 0 Ω) increase risk of oscillation and EMI; higher values (>10 Ω) degrade switching speed and increase conduction losses. Layout-dependent parasitic inductance may require empirical tuning between 2 Ω and 5 Ω.
