Product details
Overview
ADP3418JR-REEL from Analog Devices is a dual bootstrapped 12 V MOSFET driver with output disable, designed to drive high-side and low-side N-channel MOSFETs in synchronous buck converters. It delivers 1.8 Ω sourcing and 1.0 Ω sinking output resistance, supports 3000 pF load drive with 20 ns propagation delay (low-side), and implements adaptive overlap protection per Intel® VRM 10 for shoot-through prevention in multiphase CPU supplies.
For engineers reviewing the ADP3418JR-REEL datasheet, ADP3418JR-REEL pinout, ADP3418JR-REEL application, or ADP3418JR-REEL equivalent, key selection criteria include bootstrapped high-side drive capability, OD-controlled floating output shutdown, nonoverlap timing control referenced to SW node voltage, and SOIC-8 packaging compatible with desktop VRM 10-compliant power stages.
Technical Context
The ADP3418JR-REEL integrates independent high-side and low-side drivers sharing a single PWM input: DRVH operates in-phase with IN and uses BST/SW bootstrap biasing, while DRVL operates 180° out-of-phase and references VCC/PGND. Its overlap protection circuit monitors SW node voltage to enforce ≥1 V threshold before low-side turn-on and applies fixed 50 ns delay before high-side turn-on after low-side turn-off.
It features integrated output disable (OD) logic that forces both DRVH and DRVL low simultaneously, enabling controlled output capacitor discharge during system shutdown. The driver operates across 4.15 V to 13.2 V VCC, supports BST voltages up to VCC + 15 V, and is rated for 0°C to 85°C ambient operation in an 8-lead SOIC package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.15 V to 13.2 V - Enables direct use with 5 V, 12 V, or mixed-supply systems without external regulation. |
| High-Side Output Resistance | 1.8 Ω sourcing / 1.0 Ω sinking - Ensures fast gate charging/discharging of high-Qg N-channel MOSFETs in buck topologies. |
| Low-Side Propagation Delay | 10–20 ns (tpdlDRVL) - Guarantees tight timing control for high-frequency switching up to 500 kHz. |
| SW Node Voltage Threshold | ~1 V detection level - Triggers low-side turn-on only after high-side fully commutates, preventing shoot-through. |
| Output Disable Response | 15–40 ns tpdhOD/tpdlOD - Provides rapid, synchronized shutdown of both outputs during fault or power-down sequences. |
| Thermal Resistance (θJA) | 90°C/W on 4-layer board - Supports sustained operation at full load in compact VRM layouts with adequate copper area. |
Pinout & Package
ADP3418JR-REEL is housed in an 8-lead SOIC package (JEDEC MS-012AA, RN-8), with 1.27 mm lead pitch and standard gull-wing leads. Thermal performance is optimized for 4-layer PCBs (θJA = 90°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BST (Pin 1) | Bootstrap supply input | Accepts external capacitor (100 nF–1 µF) to generate floating bias for high-side driver; rated up to VCC + 15 V. |
| IN (Pin 2) | PWM logic input | Single TTL/CMOS-compatible signal controlling both drivers; 0.8 V low / 3.5 V high thresholds ensure noise immunity. |
| OD (Pin 3) | Output disable control | Active-low signal forcing DRVH and DRVL low simultaneously; enables VRM 10-compliant output float during shutdown. |
| VCC (Pin 4) | Main supply input | Power source for low-side driver and internal logic; requires local 4.7 µF ceramic bypass to PGND. |
| DRVL (Pin 5) | Low-side gate drive output | Drives ground-referenced N-MOSFET; 180° out-of-phase with IN; sinks 2.5 A peak (calculated from Rds(on) and VCC). |
| PGND (Pin 6) | Power ground return | Direct connection point to low-side MOSFET source; critical for minimizing ground bounce in high-di/dt paths. |
| SW (Pin 7) | Switching node monitor | Connects to buck converter phase node; used by overlap circuit to detect voltage decay to ~1 V before enabling DRVL. |
| DRVH (Pin 8) | High-side gate drive output | Drives floating N-MOSFET source; in-phase with IN; referenced to SW; supports 12 V gate drive swing under bootstrap operation. |
Key Features
| Feature | Design Value |
|---|---|
| All-in-one synchronous buck driver | Eliminates need for separate high-side and low-side drivers or external logic, reducing BOM count and layout complexity. |
| Bootstrapped high-side drive | Enables use of efficient N-channel MOSFETs on high-side without requiring isolated supplies or charge pumps. |
| Anticross-conduction protection | Adaptive SW-node sensing + fixed 50 ns delay prevents simultaneous conduction, eliminating shoot-through losses and thermal stress. |
| Output disable control | Hardware-level OD pin ensures deterministic, glitch-free shutdown of both outputs-critical for VRM 10 compliance and safe power sequencing. |
| 3000 pF load drive capability | Supports modern low-RDS(on) MOSFETs with gate charges up to ~20 nC at 500 kHz switching frequency. |
Applications
| Multiphase Desktop CPU Supply | Single-Supply Synchronous Buck Converter |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5109BMM/NOPB | Single high-side/low-side driver with independent INH/INL inputs; no integrated SW-sense overlap logic; 5 V–14 V VCC range. | Lacks adaptive SW-threshold overlap protection; requires external timing components for shoot-through prevention. | Choose when separate control of high/low sides is needed and SW-sensing is implemented externally. |
| MP6610DQKT-LF-Z | Monolithic 2A dual driver with integrated bootstrap diode; 4.5 V–16 V VCC; no OD pin; fixed 120 ns dead time. | Missing output disable functionality and SW-node adaptive timing; uses internal bootstrap diode instead of external. | Prefer for cost-sensitive, space-constrained designs where OD and precise VRM 10 timing are not required. |
Compared with LM5109BMM/NOPB and MP6610DQKT-LF-Z, the ADP3418JR-REEL uniquely combines SW-sensed adaptive overlap protection, hardware OD control for VRM 10 compliance, and SOIC-8 manufacturability-making it the only option among the three qualified for Intel desktop CPU power stages requiring guaranteed 1 V SW threshold enforcement and synchronized shutdown.

FAQ
What is the maximum allowable BST voltage for the ADP3418JR-REEL?
The ADP3418JR-REEL supports a BST voltage up to VCC + 15 V, with absolute maximum rating of –0.3 V to VCC + 15 V. This allows reliable operation with 12 V VCC and up to 27 V on BST, accommodating typical bootstrap voltage swings in 12 V input buck converters. Exceeding this limit risks permanent damage to the high-side driver stage.
Does the ADP3418JR-REEL require an external bootstrap diode?
Yes, the ADP3418JR-REEL requires an external bootstrap diode connected between VCC and BST pins. The datasheet specifies a minimum 15 V diode rating and recommends small-signal types like 1N4148WS. Unlike some newer drivers, ADP3418JR-REEL does not integrate the bootstrap diode, giving designers flexibility in selecting diode speed and voltage rating.
How does the overlap protection circuit in the ADP3418JR-REEL prevent shoot-through?
The ADP3418JR-REEL uses dual-method overlap protection: (1) SW node voltage sensing delays DRVL turn-on until SW falls below ~1 V after DRVH turn-off; and (2) a fixed 50 ns delay inserted before DRVH turn-on after DRVL turn-off. This combination ensures neither MOSFET conducts simultaneously, eliminating shoot-through current regardless of temperature, supply, or MOSFET parameter variation.
What is the purpose of the OD pin on the ADP3418JR-REEL?
The OD (Output Disable) pin on the ADP3418JR-REEL is an active-low control that forces both DRVH and DRVL outputs low simultaneously, disconnecting both MOSFET gates and allowing the output to float. This feature directly supports Intel® VRM 10 specification requirements for controlled output capacitor discharge during system shutdown or fault conditions.
Can the ADP3418JR-REEL drive MOSFETs with gate charges exceeding 20 nC?
The ADP3418JR-REEL is characterized to drive 3000 pF loads with specified timing, correlating to ~20 nC for typical 12 V gate drive. While higher gate charge MOSFETs may function, propagation delays and transition times will increase beyond datasheet limits, potentially compromising overlap timing margins and efficiency. For >20 nC, verify timing margins using actual gate charge and load capacitance in simulation or bench testing.
