Product details
Overview
ADP3414JRZ-REEL-AD from Analog Devices is a dual bootstrapped N-channel MOSFET driver optimized for synchronous buck converters, featuring 3.5 Ω high-side sourcing resistance, 2.5 Ω low-side sinking resistance, and integrated overlap protection to prevent shoot-through. It drives both upper and lower FETs using a single PWM input and supports VCC from 4.15 V to 7.5 V - used in Intel/AMD CPU core power supplies.
For engineers reviewing the ADP3414JRZ-REEL-AD datasheet, ADP3414JRZ-REEL-AD pinout, ADP3414JRZ-REEL-AD application, or ADP3414JRZ-REEL-AD equivalent, key selection criteria include bootstrap-compatible high-side drive capability, nonoverlap timing control at SW node, propagation delay ≤86 ns (DRVH), and SOIC-8 packaging with NC pin awareness.
Technical Context
The ADP3414JRZ-REEL-AD implements adaptive overlap protection by monitoring SW node voltage (requiring <1 V before DRVL turn-on) and applying fixed 50 ns internal delay for DRVH turn-on after DRVL turn-off. Its high-side driver operates referenced to SW, not PGND, enabling floating gate drive up to +25 V on SW and +30 V on BST.
It accepts TTL-level IN input (VIH ≥ 2.3 V, VIL ≤ 0.8 V), delivers 20–30 ns transition times into 3 nF loads, and maintains output resistance specs across VCC = 5 V and 7 V - confirming robust gate drive performance under typical CPU VRM supply conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.15 V to 7.5 V - compatible with standard 5 V or 7 V bias rails in multiphase CPU VRMs |
| High-Side Sourcing Resistance | 2.0 Ω (typ.) at VBST–VSW = 7 V - ensures fast turn-on of high Rg N-channel MOSFETs |
| Low-Side Sinking Resistance | 1.0 Ω (typ.) at VCC = 7 V - enables sub-25 ns fall time into 3 nF load |
| Propagation Delay (DRVH) | 65–86 ns (tpdhDRVH) - defines maximum timing uncertainty in high-side switching path |
| Overlap Protection Threshold | SW voltage must fall to ≤1 V before DRVL activation - prevents shoot-through across wide temperature/voltage ranges |
| Package | 8-Lead SOIC (R-8), 5.0 mm × 4.0 mm - industry-standard footprint with exposed thermal pad not present |
Pinout & Package
ADP3414JRZ-REEL-AD is housed in an 8-lead narrow-body SOIC package (JEDEC MS-012AA, R-8). Pin 3 is NC (no connection); all other pins are electrically active and thermally isolated per layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BST (Pin 1) | Floating bootstrap supply rail | Charged via external diode/capacitor to generate gate drive voltage above SW node; supports up to +30 V BST-to-PGND |
| IN (Pin 2) | PWM input signal | TTL-compatible control input; determines phase relationship: DRVH follows IN, DRVL is inverted |
| NC (Pin 3) | No connection | Must remain unconnected; no internal bond wire or circuitry attached |
| VCC (Pin 4) | Logic and low-side driver supply | Bypassed with 1 µF ceramic capacitor to PGND; powers internal logic and DRVL stage |
| DRVL (Pin 5) | Low-side MOSFET gate driver output | Sinks/sourcing current to drive synchronous rectifier FET; referenced to PGND |
| PGND (Pin 6) | Power ground return | Direct connection point for lower FET source and VCC bypass capacitor ground |
| SW (Pin 7) | Switching node monitor/return | Connects to buck converter switch node; serves as floating reference for DRVH and overlap detection |
| DRVH (Pin 8) | High-side MOSFET gate driver output | Output referenced to SW, not PGND; requires bootstrap circuit for operation above VCC |
Key Features
| Feature | Design Value |
|---|---|
| All-in-one synchronous buck driver | Single IC replaces discrete high/low-side drivers and timing logic - reduces BOM count and layout complexity |
| Bootstrapped high-side drive | Enables use of cost-effective N-channel MOSFETs on high side without isolated supply or charge pump |
| Anticross-conduction protection | Hardware-enforced dead-time via SW voltage sensing and fixed 50 ns delay - eliminates need for external timing components |
| Pulse-by-pulse disable control | IN pin can be pulled low to immediately disable both outputs - supports cycle-by-cycle current limiting schemes |
| 3000 pF load drive capability | Validated 20–47 ns transition times into 3 nF capacitive load - sufficient for modern low-RDS(on) MOSFETs |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel MOSFET driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5109BMM/NOPB | Higher VBST rating (65 V), but no SW-sensed overlap protection - relies on fixed dead-time | Preferred for industrial DC/DC where SW node voltage exceeds 25 V; less suitable for CPU VRMs demanding adaptive timing | Select LM5109BMM/NOPB when operating above 25 V SW or requiring extended BST voltage range |
| MP6610DQKT-LF-Z | Integrated bootstrap diode, 5 V–16 V VCC range, but only 100 mA peak drive current vs. ADP3414's 2 A capability | Better suited for low-power portable applications (<10 A); insufficient gate drive strength for CPU core phases | Choose MP6610DQKT-LF-Z for space-constrained battery-powered systems needing integrated diode |
Compared with LM5109BMM/NOPB and MP6610DQKT-LF-Z, the ADP3414JRZ-REEL-AD uniquely combines SW-node adaptive overlap protection, 2 A peak drive capability, and SOIC-8 compatibility - making it the preferred choice for high-current, tightly timed CPU core power stages where shoot-through prevention is critical.

FAQ
What is the maximum allowable voltage on the BST pin of the ADP3414JRZ-REEL-AD?
The absolute maximum rating for the BST pin is +30 V relative to PGND. This allows the ADP3414JRZ-REEL-AD to operate with high input voltages common in CPU VRMs - for example, when VIN = 12 V and the bootstrap capacitor charges to ~19 V, staying safely within limit. Exceeding +30 V risks permanent damage.
Does the ADP3414JRZ-REEL-AD require an external bootstrap diode?
Yes, the ADP3414JRZ-REEL-AD requires an external Schottky diode (e.g., MBR052LTI) between VCC and BST to charge the bootstrap capacitor during low-side conduction. The IC contains no integrated diode; omission causes failure of high-side drive after initial startup.
Can the ADP3414JRZ-REEL-AD drive both MOSFETs in a half-bridge configuration?
No - the ADP3414JRZ-REEL-AD is designed exclusively for synchronous buck topologies where DRVH drives the high-side switch and DRVL drives the low-side synchronous rectifier. It lacks the floating high-side supply and level-shifting architecture required for true half-bridge (e.g., motor drive) applications.
What is the purpose of the NC pin (Pin 3) on the ADP3414JRZ-REEL-AD?
Pin 3 is designated NC (No Connection) in the ADP3414JRZ-REEL-AD datasheet and must remain unconnected on the PCB. It has no internal bond wire or circuit function; routing traces or placing vias to this pin may cause parasitic coupling or mechanical stress without electrical benefit.
How does the overlap protection circuit in the ADP3414JRZ-REEL-AD respond to rapid load transients?
The ADP3414JRZ-REEL-AD overlap protection uses real-time SW node voltage monitoring - not fixed timers - so it dynamically adapts to load-induced dV/dt changes. During fast load steps, the circuit still enforces ≤1 V SW threshold before enabling DRVL, ensuring robust shoot-through prevention independent of slew rate.
