Product details
Overview
ADP3415LRM-REEL-AD from ON Semiconductor is a dual N-channel MOSFET driver optimized for synchronous buck converters, featuring bootstrapped high-side drive (DRVH), low-side drive (DRVL), programmable transition delay via DLY pin, anticross-conduction protection, and undervoltage lockout. It delivers 1.5 Ω typical high-side output resistance (DRVH–BST), <100 µA shutdown quiescent current, and operates across 0°C to 100°C in a 10-lead MSOP package - used in mobile CPU core power supplies requiring precise gate timing and shoot-through prevention.
For engineers reviewing the ADP3415LRM-REEL-AD datasheet, ADP3415LRM-REEL-AD pinout, ADP3415LRM-REEL-AD application, or ADP3415LRM-REEL-AD equivalent, key selection criteria include bootstrapped high-side drive capability, zero-crossing adaptive overlap control, DRVLSD-controlled synchronous rectifier disable, thermal shutdown at 165°C, and compatibility with 20 A notebook PC CPU regulators.
Technical Context
The ADP3415LRM-REEL-AD implements adaptive overlap protection by monitoring SW node voltage (1.6 V zero-crossing threshold) to sequence DRVL turn-on after DRVH turn-off, while using an external resistor on DLY to program fixed delay for DRVH turn-on after DRVL turn-off. Its high-side driver operates from a floating BST–SW rail, supporting up to +30 V BST-to-GND and +25 V SW-to-GND absolute ratings.
It integrates undervoltage lockout (4.15 V typical threshold, 50 mV hysteresis), thermal shutdown (165°C trip, 10°C hysteresis), and independent shutdown (SD) and low-side disable (DRVLSD) inputs with TTL-compatible logic thresholds (VIH = 2.0 V, VIL = 0.8 V). Propagation delays are tightly specified: tpdhDRVH = 10–40 ns, tpdlDRVL = 10–25 ns, and SW timeout tSWTO = 130–300 ns.

Key Features
| Feature | Design Value |
|---|---|
| Adaptive Overlap Protection Circuitry | Monitors SW node voltage to enforce non-overlapping FET conduction, eliminating shoot-through regardless of temperature or FET Qg variation |
| Programmable Transition Delay (DLY pin) | External resistor sets precise delay between DRVL turn-off and DRVH turn-on, enabling optimization for specific high-side FET gate charge and body diode recovery |
| Zero-Crossing Synchronous Drive Control | Triggers DRVL turn-on only after SW falls below 1.6 V, ensuring high-side FET is fully off before low-side activation |
| Synchronous Override Control (DRVLSD) | Allows system state logic to disable DRVL independently, enabling discontinuous conduction mode for improved light-load efficiency |
| Undervoltage Lockout with Hysteresis | Holds all outputs low until VCC reaches 4.15 V (±250 mV), then maintains operation down to 4.1 V to prevent erratic switching during brownout |

FAQ
What is the function of the DLY pin on the ADP3415LRM-REEL-AD?
The DLY pin on the ADP3415LRM-REEL-AD programs a fixed delay between DRVL turn-off and DRVH turn-on using an external resistor to ground. This delay - adjustable from 100 ns to 200 ns - prevents overlap during high-side FET turn-on by accommodating variations in external MOSFET gate charge and body diode recovery time. The ADP3415LRM-REEL-AD datasheet specifies RDLY ≥ 120 kΩ for nominal delay, and the feature is absent in many competing drivers lacking programmable dead-time control.
How does the ADP3415LRM-REEL-AD implement anticross-conduction protection?
The ADP3415LRM-REEL-AD implements anticross-conduction protection through two mechanisms: (1) adaptive zero-crossing detection that monitors the SW node and delays DRVL turn-on until voltage falls to 1.6 V, and (2) a programmable DLY pin delay for DRVH turn-on after DRVL turn-off. These features ensure neither N-FET conducts simultaneously, eliminating shoot-through current even under temperature, voltage, or FET parameter variation. The ADP3415LRM-REEL-AD also includes a 300 ns SW timeout (tSWTO) to force DRVL activation if SW fails to collapse.
What is the maximum allowable voltage on the BST pin of the ADP3415LRM-REEL-AD?
The BST pin of the ADP3415LRM-REEL-AD has an absolute maximum rating of –0.3 V to +30 V relative to GND, and –0.3 V to +7 V relative to SW. This allows safe operation with high-input-voltage buck converters where BST swings to VDCIN + VCC during high-side conduction. The ADP3415LRM-REEL-AD's BST rail must be charged via an external Schottky diode and capacitor; exceeding +30 V risks permanent damage, and design margins should maintain at least 10% derating below this limit.
Can the ADP3415LRM-REEL-AD drive both high-side and low-side N-channel MOSFETs in a synchronous buck converter?
Yes, the ADP3415LRM-REEL-AD is explicitly designed to drive two N-channel MOSFETs in a nonisolated synchronous buck topology: DRVH drives the high-side switch using a bootstrapped BST–SW supply, while DRVL drives the low-side synchronous rectifier referenced to VCC and GND. Its output resistances (1.5 Ω DRVH–BST, 1.0 Ω DRVL–GND), 20 ns transition times, and adaptive overlap control make the ADP3415LRM-REEL-AD suitable for 20 A CPU core regulators where N-FET efficiency outweighs P-FET simplicity.
What thermal protection features does the ADP3415LRM-REEL-AD include?
The ADP3415LRM-REEL-AD includes thermal shutdown that disables both DRVH and DRVL outputs when junction temperature exceeds 165°C, with 10°C hysteresis to prevent oscillation. This protection is independent of UVLO and shutdown pin behavior, activating only under sustained overtemperature conditions such as inadequate heatsinking or excessive ambient temperature. The ADP3415LRM-REEL-AD resumes normal operation automatically once TJ drops below 155°C, and its MSOP package includes thermal pad recommendations for PCB copper pour to maximize heat dissipation.
