Product details
Overview
ADP3413JR-REEL from Analog Devices is a dual bootstrapped MOSFET driver optimized for synchronous buck converters, driving two N-channel MOSFETs with 20 ns propagation delay (high-side), 30 ns transition time, and integrated anticross-conduction protection. It enables single-PWM control of high-side (DRVH) and low-side (DRVL) switches in CPU core power supplies.
For engineers reviewing the ADP3413JR-REEL datasheet, ADP3413JR-REEL pinout, ADP3413JR-REEL application, or ADP3413JR-REEL equivalent, key selection criteria include bootstrap-enabled high-side drive capability (BST–SW up to 30 V), OD-controlled fast disable (<30 ns propagation), and SOIC-8 packaging compatible with multiphase desktop CPU supply designs.
Technical Context
The ADP3413JR-REEL implements adaptive overlap protection by monitoring SW node voltage (turn-on of DRVL delayed until SW ≤1 V) and enforcing a fixed 50 ns internal delay before DRVH turn-on after DRVL turn-off. Its high-side driver uses external bootstrap (BST/SW pins) to sustain gate drive during high dv/dt switching, while the low-side driver operates referenced to PGND and VCC.
Both drivers deliver <3.5 Ω sourcing and <2.5 Ω sinking output resistance at 7 V supply, enabling 3 nF load drive with sub-50 ns rise/fall times. The OD pin provides TTL-compatible, high-speed disable (15–30 ns propagation) that forces both DRVH and DRVL low, eliminating shoot-through risk during fault or standby conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.15 V to 7.5 V - Supports standard 5 V and 7 V bias rails without external regulation. |
| High-Side Propagation Delay | 65–86 ns - Enables precise timing control in high-frequency buck converters (>1 MHz). |
| Low-Side Propagation Delay | 17–35 ns - Ensures rapid response to PWM edges for tight duty-cycle control. |
| Bootstrap Voltage Range (BST–SW) | –0.3 V to +8 V - Accommodates typical bootstrap capacitor droop and transient undershoot. |
| Output Disable Propagation | 15–30 ns - Guarantees fast shutdown to prevent shoot-through during fault events. |
| Operating Temperature Range | 0°C to +70°C - Qualified for commercial-grade CPU core power applications. |
| Package | 8-Lead SOIC (R-8) - Standard surface-mount footprint with 155°C/W junction-to-ambient thermal resistance. |
Pinout & Package
ADP3413JR-REEL is housed in an 8-lead narrow-body SOIC package (JEDEC MS-012AA, R-8). Pin 1 is marked with a dot; top-view pin order is BST (1), IN (2), OD (3), VCC (4), DRVL (5), PGND (6), SW (7), DRVH (8).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BST | Floating bootstrap supply input | Holds charge for high-side gate drive; requires 100 nF–1 µF ceramic capacitor between BST and SW. |
| IN | PWM input signal | TTL-compatible control input; drives both DRVH (in-phase) and DRVL (180° out-of-phase). |
| OD | Output disable control | Active-low TTL input; forces DRVH and DRVL low within ≤30 ns to halt converter operation. |
| VCC | Main supply input | 4.15–7.5 V bias rail; requires local 1 µF ceramic bypass to PGND for noise suppression. |
| DRVL | Low-side MOSFET gate drive output | PGND-referenced output driving synchronous rectifier; sinks/sourcing current via VCC/PGND path. |
| PGND | Power ground reference | Must be connected directly to source of low-side MOSFET to minimize ground bounce and OCP accuracy error. |
| SW | Switching node monitor | Connects to buck node; used by overlap circuit to detect voltage decay before enabling DRVL. |
| DRVH | High-side MOSFET gate drive output | Bootstrap-referenced output driving upper N-MOSFET; turns on/off in phase with IN signal. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated anticross-conduction protection | Adaptive SW-node sensing + fixed 50 ns delay prevents simultaneous conduction of Q1/Q2, eliminating shoot-through losses. |
| Single-PWM dual-drive architecture | One IN signal generates complementary DRVH/DRVL outputs - reduces controller complexity and PCB routing. |
| Fast output disable with propagation control | OD pin asserts within 15–30 ns to force both outputs low, enabling system-level fault response and power sequencing. |
| High-current gate drive capability | ≤3.5 Ω sourcing / ≤2.5 Ω sinking resistance supports 3 nF loads with <50 ns transitions - suitable for low-RDS(on) MOSFETs. |
| Robust bootstrap interface | BST–SW rating up to +8 V and SW node tolerance to –5 V to +25 V enable reliable high-side operation across wide input ranges. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual MOSFET driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IR2110SPBF | Higher voltage rating (600 V high-side), but no integrated overlap protection; requires external logic for shoot-through prevention. | Targeted at half-bridge motor drives and isolated DC-DC, not optimized for low-voltage CPU buck topologies. | Choose when >100 V bus operation or isolation is needed; avoid for sub-12 V synchronous buck due to lack of SW-sense ODP. |
| LM5113MMX/NOPB | Separate high/low inputs, no built-in anticross-conduction; faster propagation (15 ns typ), but requires external timing control. | Designed for high-frequency GaN/SiC applications; lacks bootstrap voltage monitoring and SW node interface. | Select for >1 MHz GaN-based converters where external dead-time control is preferred; not drop-in for ADP3413JR-REEL CPU supply designs. |
Compared with IR2110SPBF and LM5113MMX/NOPB, the ADP3413JR-REEL uniquely integrates SW-node–based overlap protection and single-PWM operation-reducing external component count and simplifying timing validation in sub-12 V synchronous buck CPU supplies.

FAQ
What is the maximum allowable voltage on the BST pin relative to SW for ADP3413JR-REEL?
The BST pin supports a voltage range of –0.3 V to +8 V relative to SW, as specified in the Absolute Maximum Ratings table. This allows safe operation with typical bootstrap capacitor droop and transient undershoot during high-frequency switching. Exceeding +8 V BST–SW may cause permanent damage to the ADP3413JR-REEL internal high-side driver circuitry.
Does ADP3413JR-REEL require external components for bootstrap operation?
Yes, ADP3413JR-REEL requires an external Schottky diode and bootstrap capacitor (CBST) connected between BST and SW pins. A minimum 100 nF ceramic capacitor rated ≥50 V is recommended; the diode must withstand ≥40 V and exhibit low forward voltage to maximize gate drive margin. These components are mandatory for high-side operation of the ADP3413JR-REEL.
How does the overlap protection circuit in ADP3413JR-REEL prevent shoot-through?
The ADP3413JR-REEL uses dual-method overlap protection: (1) SW node voltage sensing delays DRVL turn-on until SW falls to ≤1 V after DRVH turn-off, and (2) a fixed 50 ns internal delay prevents DRVH turn-on until DRVL has fully turned off. This ensures neither MOSFET conducts simultaneously, eliminating shoot-through current in the ADP3413JR-REEL-driven buck stage.
Can ADP3413JR-REEL drive 3 nF gate loads with sub-50 ns transition times?
Yes, ADP3413JR-REEL is characterized to drive 3 nF loads with trDRVH = 36–47 ns, tfDRVH = 20–30 ns, trDRVL = 27–35 ns, and tfDRVL = 19–26 ns at VCC = 7 V. These values are guaranteed across temperature and supply variations, confirming robust performance for low-RDS(on) MOSFETs commonly used with ADP3413JR-REEL in CPU power stages.
What is the function of the OD pin on ADP3413JR-REEL, and what logic level disables the outputs?
The OD (Output Disable) pin on ADP3413JR-REEL is an active-low TTL-compatible control input. When pulled below 0.8 V (VIL), it forces both DRVH and DRVL outputs low within 15–30 ns, halting buck converter operation. This feature enables fast fault response, power sequencing, and standby mode control in systems using ADP3413JR-REEL.
